Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Note 1 — Nature of Operations AmeriGas Partners is a publicly traded limited partnership that conducts a national propane distribution business through its principal operating subsidiary, AmeriGas OLP. AmeriGas Partners and AmeriGas OLP are Delaware limited partnerships. AmeriGas Partners, AmeriGas OLP and all of their subsidiaries are collectively referred to herein as the Partnership. AmeriGas OLP is engaged in the distribution of propane and related equipment and supplies. AmeriGas OLP comprises the largest retail propane distribution business in the United States serving residential, commercial, industrial, motor fuel and agricultural customers in all 50 states. At June 30, 2019 , the General Partner, an indirect wholly owned subsidiary of UGI, held a 1% general partner interest in AmeriGas Partners and a 1.01% general partner interest in AmeriGas OLP. The General Partner also owns AmeriGas Partners Common Units. The remaining Common Units outstanding represents publicly held Common Units. AmeriGas Partners holds a 98.99% limited partner interest in AmeriGas OLP. AmeriGas Partners and AmeriGas OLP have no employees. Employees of the General Partner conduct, direct and manage our operations. The General Partner is reimbursed monthly for all direct and indirect expenses it incurs on our behalf (see Note 9 ). On April 1, 2019, we entered into the Merger Agreement, pursuant to which Merger Sub will merge with and into the Partnership, with the Partnership surviving as an indirect, wholly owned subsidiary of UGI. If the Merger Agreement is consummated, UGI will obtain full ownership of AmeriGas Partners by acquiring all of the outstanding Common Units not already held by the General Partner. Consummation of the Merger Agreement is subject to customary conditions as well as the approval of a majority of the outstanding Common Units including the Common Units held by the General Partner. Upon completion of the Proposed Merger, Common Units will no longer be publicly traded. Subject to the satisfaction or waiver of certain conditions, including the approval of the Merger Agreement by AmeriGas Partners’ unitholders at the Special Meeting to be held on August 21, 2019, the Proposed Merger is expected to close in the fourth quarter of Fiscal 2019. See Note 10 for further information on the Proposed Merger.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 — Summary of Significant Accounting Policies The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the SEC. They include all adjustments which we consider necessary for a fair statement of the results for the interim periods presented. Such adjustments consist only of normal recurring items unless otherwise disclosed. The September 30, 2018 , Condensed Consolidated Balance Sheet was derived from audited financial statements but does not include all footnote disclosures from the annual financial statements. These financial statements should be read in conjunction with the Partnership’s 2018 Annual Report. Weather significantly impacts demand for propane and profitability because many customers use propane for heating purposes. Due to the seasonal nature of the Partnership’s propane business, the results of operations for interim periods are not necessarily indicative of the results to be expected for a full year. Principles of Consolidation. The consolidated financial statements include the accounts of AmeriGas Partners, its majority-owned subsidiary AmeriGas OLP, and its 100% -owned finance subsidiaries AmeriGas Finance Corp., AmeriGas Eagle Finance Corp., AP Eagle Finance Corp., and AmeriGas Finance LLC. AmeriGas Partners and AmeriGas OLP are under the common control of the General Partner. The General Partner of AmeriGas OLP, which is also the General Partner of AmeriGas Partners, makes all decisions for AmeriGas OLP; limited partners of AmeriGas OLP do not have the ability to remove the General Partner or participate in the decision-making for AmeriGas OLP. The accounts of AmeriGas OLP are included based upon the determination that AmeriGas Partners has a controlling financial interest in and is the primary beneficiary of AmeriGas OLP. We eliminate intercompany accounts and transactions when we consolidate. Revenue Recognition. Effective October 1, 2018, the Partnership adopted ASU No. 2014-09, “Revenue from Contracts with Customers,” which, as amended, is included in ASC 606. This new accounting guidance supersedes previous revenue recognition requirements in ASC 605. ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Partnership adopted this new accounting guidance using the modified retrospective transition method to those contracts which were not completed as of October 1, 2018. Periods prior to October 1, 2018, have not been restated and continue to be reported in accordance with ASC 605. Upon adoption, there were no cumulative effect adjustments made to the October 1, 2018, partners’ capital balances. The adoption of ASC 606 did not, and is not expected to, have a material impact on the amount or timing of our revenue recognition and on our consolidated net income, cash flows or financial position. Certain revenues are not within the scope of ASC 606 such as revenue from leases, financial instruments, other revenues that are not from contracts with customers, and other contractual rights or obligations and we account for such revenues in accordance with other GAAP. Revenue-related taxes collected on behalf of customers and remitted to taxing authorities, principally sales and use taxes, are not included in revenues. The Partnership has elected to use the practical expedient to expense the costs to obtain contracts when incurred as such amounts are generally not material. See Note 4 for additional disclosures regarding the Partnership’s revenue from contracts with customers. Allocation of Net Income (Loss) . Net income (loss) attributable to AmeriGas Partners, L.P. for partners’ capital and statement of operations presentation purposes is allocated to the General Partner and the limited partners in accordance with their respective ownership percentages after giving effect to amounts distributed to the General Partner in excess of its 1% general partner interest in AmeriGas Partners based on its IDRs under the Partnership Agreement. Income (Loss) Per Unit. Income (loss) per limited partner unit is computed in accordance with GAAP regarding the application of the two-class method for determining income (loss) per unit for MLPs when IDRs are present. The two-class method requires that income per limited partner unit be calculated as if all earnings for the period were distributed and requires a separate calculation for each quarter and year-to-date period. In periods when our net income attributable to AmeriGas Partners exceeds our Available Cash, as defined in the Partnership Agreement, and is above certain levels, the calculation according to the two-class method results in an increased allocation of undistributed earnings to the General Partner. Generally, in periods when our Available Cash in respect of the quarter or year-to-date periods exceeds our net income (loss) attributable to AmeriGas Partners, the calculation according to the two-class method results in an allocation of earnings to the General Partner greater than its relative ownership interest in the Partnership (or in the case of a net loss attributable to AmeriGas Partners, an allocation of such net loss to the Common Unitholders greater than their relative ownership interest in the Partnership). The following table sets forth reconciliations of the numerators and denominators of the basic and diluted income per limited partner unit computations: Three Months Ended Nine Months Ended 2019 2018 2019 2018 Net (loss) income attributable to AmeriGas Partners, L.P. $ (48,957 ) $ (74,396 ) $ 214,663 $ 221,849 Adjust for general partner share and theoretical distributions of net (loss) income attributable to AmeriGas Partners, L.P. to the general partner in accordance with the two-class method for MLPs (10,844 ) (10,587 ) (36,170 ) (36,215 ) Common Unitholders’ interest in net (loss) income attributable to AmeriGas Partners, L.P. under the two-class method for MLPs $ (59,801 ) $ (84,983 ) $ 178,493 $ 185,634 Weighted average Common Units outstanding — basic (thousands) 93,098 93,042 93,077 93,031 Potentially dilutive Common Units (thousands) — — 44 51 Weighted average Common Units outstanding — diluted (thousands) 93,098 93,042 93,121 93,082 There was no dilutive effect based upon the computation of income (loss) per limited partner unit in accordance with the two-class method for the three and nine months ended June 30, 2019 and 2018 . Potentially dilutive Common Units included in the diluted limited partner units outstanding computation reflect the effects of restricted Common Unit awards granted under the General Partner’s incentive compensation plans. Derivative Instruments. Derivative instruments are reported on the Condensed Consolidated Balance Sheets at their fair values, unless the NPNS exception is elected. The accounting for changes in fair value depends upon the purpose of the derivative instrument and whether it qualifies and is designated as a hedge for accounting purposes. We do not currently have derivative instruments that are designated and qualify as cash flow hedges. Changes in the fair values of our commodity derivative instruments are reflected in “Cost of sales — propane” on the Condensed Consolidated Statements of Operations. Cash flows from commodity derivative instruments are included in cash flows from operating activities on the Condensed Consolidated Statements of Cash Flows. For a more detailed description of the derivative instruments we use, our accounting for derivatives, our objectives for using them and other information, see Note 8 . Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and costs. These estimates are based on management’s knowledge of current events, historical experience and various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may be different from these estimates and assumptions. Correction of Prior Period Errors. During the three and nine months ended June 30, 2019, the Partnership determined that it had not properly recorded expenses associated with certain vehicle lease arrangements. The Partnership evaluated the impact of the error on prior periods and determined that the effect was not material to the financial statements for the three and nine months ended June 30, 2019, or any prior period financial statements, and recorded the cumulative effect of the error in accounting for certain vehicle lease arrangements as of April 1, 2019. The correction of the error increased “Operating and administrative expenses” for the three months ended June 30, 2019, by $5,025 substantially all of which relates to periods prior to Fiscal 2019.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Accounting Changes	Note 3 — Accounting Changes New Accounting Standards Adopted Effective October 1, 2018 Revenue Recognition. Effective October 1, 2018, the Partnership adopted new accounting guidance regarding revenue recognition. See Notes 2 and 4 for a detailed description of the impact of the new guidance and related disclosures. Cloud Computing Implementation Costs. In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The new guidance requires a customer in a cloud computing arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. These deferred implementation costs are expensed over the fixed, noncancelable term of the service arrangement plus any reasonably certain renewal periods. The new guidance also requires the entity to present the expense related to the capitalized implementation costs in the same income statement line as the hosting service fees; to classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments for hosting service fees; and to present the capitalized implementation costs in the balance sheet in the same line item in which prepaid hosting service fees are presented. The new guidance can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We adopted this ASU effective October 1, 2018, and applied the guidance prospectively to all implementation costs associated with cloud computing arrangements that are service contracts incurred beginning October 1, 2018. The adoption of the new guidance did not have a material impact on our results of operations for the three and nine months ended June 30, 2019 .

In August 2018, the FASB issued ASU No. 2018-13, “Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The amendments in this ASU are effective for annual periods beginning October 1, 2020 (Fiscal 2021). The guidance regarding removing and modifying disclosures will be adopted on a retrospective basis and the guidance regarding new disclosures will be adopted on a prospective basis. Early adoption is permitted. The Partnership expects to adopt the new guidance in the fourth quarter of Fiscal 2019. The adoption of the new guidance is not expected to have a material impact on the Partnership’s financial statements. Derivatives and Hedging. In August 2017, the FASB issued ASU No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This ASU amends and simplifies existing guidance to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The amendments in this ASU are effective for the Partnership for interim and annual periods beginning October 1, 2019 (Fiscal 2020). Early adoption is permitted. For cash flow and net investment hedges as of the adoption date, the guidance requires a modified retrospective approach. The amended presentation and disclosure guidance is required prospectively. The Partnership expects to adopt the new guidance in the first quarter of Fiscal 2020. The adoption of the new guidance is not expected to have a material impact on the Partnership’s financial statements. Credit Losses. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments. ” This ASU requires entities to estimate lifetime expected credit losses for financial instruments not measured at fair value through net income, including trade and other receivables, net investments in leases, financial receivables, debt securities, and other financial instruments, which may result in earlier recognition of credit losses. Further, the new current expected credit loss model may affect how entities estimate their allowance for loss for receivables that are current with respect to their payment terms. ASU 2016-13 is effective for the Partnership for interim and annual periods beginning October 1, 2020 (Fiscal 2021). Early adoption is permitted. The Partnership is in the process of assessing the impact on its financial statements from the adoption of the new guidance and determining the period in which the new guidance will be adopted. Leases. In February 2016, the FASB issued ASU No. 2016-02, "Leases." This ASU, as subsequently updated, amends existing guidance to require entities that lease assets to recognize the assets and liabilities for the rights and obligations created by those leases on the balance sheet. The new guidance also requires additional disclosures about the amount, timing and uncertainty of cash flows from leases. The amendments in this ASU are effective for the Partnership for interim and annual periods beginning October 1, 2019 (Fiscal 2020). Early adoption is permitted. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements unless an entity chooses the transition option in ASU 2018-11, “Leases: Targeted Improvements” which, among other things, provides entities with a transition option to recognize the cumulative-effect adjustment from the modified retrospective application to the opening balance of retained earnings in the period of adoption. We will adopt ASU No. 2016-02, as updated, effective October 1, 2019 and expect to elect the transition option which would allow the Partnership to maintain historical presentation for periods before October 1, 2019. The Partnership has completed a preliminary assessment for evaluating the impact of the guidance and anticipates that its adoption will result in a significant amount of right-of-use assets and lease liabilities for leases in effect at the adoption date. The Partnership has begun implementation activities including accumulating contracts and lease data in formats compatible with a new lease management system that will assist with the initial adoption and future reporting required by the standard.

Revenue From Contracts With Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Note 4 — Revenue from Contracts with Customers We recognize revenue when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. The Partnership generally has the right to consideration from a customer in an amount that corresponds directly with the value to the customer for our performance completed to date. As such, we elected to recognize revenue in the amount to which we have a right to invoice. We do not have a significant financing component in our contracts because we receive payment shortly before, at, or shortly after the transfer of control of the good or service. Because the period between the time the performance obligation is satisfied and payment received is one year or less , the Partnership has elected to apply the significant financing component practical expedient and no amount of consideration has been allocated as a financing component. The Partnership records revenue principally from the sale of propane to retail and wholesale customers. The primary performance obligation associated with the sale of propane is the delivery of propane to (1) the customer’s point of delivery for retail customers and (2) the customer’s specified location where propane is picked up by wholesale customers, at which point control of the propane is transferred to the customer, the performance obligation is satisfied, and the associated revenue is recognized. For contracts with retail customers that consume propane from a metered tank, the Partnership recognizes revenue as the propane is consumed, at which point we have the right to invoice, and generally invoice monthly based on consumption. Contracts with customers comprise different types of contracts with varying length terms, fixed or variable prices, and fixed or variable quantities. Contracts with our residential customers, which comprise a substantial number of our customer contracts, are generally one year or less. Customer contracts for the sale of propane include fixed-price, fixed-quantity contracts under which propane is provided to a customer at a fixed price and a fixed volume, and contracts that provide for the sale of propane at market prices at date of delivery with no fixed volumes. The Partnership offers contracts that permit customers to lock in a fixed price for their volumes for a fee and also provide customers with the option to pre-buy a fixed amount of propane at a fixed price. Amounts received under pre-buy arrangements are recorded as a contract liability when received and recorded as revenue when propane is delivered and control is transferred to the customer. Fees associated with fixed-price contracts are recorded as contract liabilities and recorded ratably over the contract period. The Partnership also distributes propane to customers in portable cylinders. Under certain contracts, filled cylinders are delivered, and control is transferred, to a reseller. In such instances, the reseller is our customer and we record revenue upon delivery to the reseller. Under other contracts, filled cylinders are delivered to a reseller, but the Partnership retains control of the cylinders. In such instances, we record revenue at the time the reseller transfers control of the cylinder to the customer. Certain retail propane customers receive credits which we account for as variable consideration. We estimate these credits based upon past practices and historical customer experience and we reduce our revenues recognized for these credits. Other revenues from contracts with customers are generated primarily from certain fees the Partnership charges associated with the delivery of propane including hazmat safety compliance, inspection, metering, installation, fuel recovery and certain other services. Revenues from fees are typically recorded when the propane is delivered to the customer or the associated service is completed. Other revenues from contracts with customers are also generated from the Partnership’s parts and service business. The performance obligations of this business include installation and repair services. The performance obligations under these contracts are satisfied, and revenue is recognized, as control of the product is transferred or the services are rendered. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers or cash receipts. Contract assets represent the Partnership’s right to consideration after the performance obligations have been satisfied when such right is conditioned on something other than the passage of time. Contract assets were not material at June 30, 2019 . Substantially all of the Partnership’s receivables are unconditional rights to consideration and are included in “Accounts receivable” on the Condensed Consolidated Balance Sheets. Amounts billed are generally due within the following month. Contract liabilities arise when payment from a customer is received before the performance obligations have been satisfied and represent the Partnership’s obligations to transfer goods or services to a customer for which the Partnership has received consideration from the customer. The balances of contract liabilities were $54,836 and $93,393 at June 30, 2019 and October 1, 2018, respectively, and are included in “Customer deposits and advances” and “Other current liabilities” on the Condensed Consolidated Balance Sheets. Revenue recognized for the nine months ended June 30, 2019 , from the amount included in contract liabilities at October 1, 2018 was $74,154 . Revenue Disaggregation The following table presents our disaggregated revenues for the three and nine months ended June 30, 2019 : Three Months Ended June 30, 2019 Nine Months Ended June 30, 2019 Revenues from contracts with customers: Propane: Retail $ 405,817 $ 2,002,361 Wholesale 8,785 55,034 Other 48,235 165,945 Total revenues from contracts with customers 462,837 2,223,340 Other revenues (a) 15,897 47,198 Total revenues $ 478,734 $ 2,270,538 (a) Primarily represents revenues from tank rentals that are not within the scope of ASC 606 and accounted for in accordance with other GAAP.

Amortization expense of intangible assets was $30,085 and $29,568 for the nine months ended June 30, 2019 and 2018 , respectively. No amortization expense is included in cost of sales on the Condensed Consolidated Statements of Operations. The estimated aggregate amortization expense of intangible assets for the remainder of Fiscal 2019 and the next four fiscal years is as follows: remainder of Fiscal 2019 — $10,059 ; Fiscal 2020 — $39,152 ; Fiscal 2021 — $35,914 ; Fiscal 2022 — $32,963 ; Fiscal 2023 — $31,627 . In April 2018, a plan to discontinue the use of indefinite-lived tradenames and trademarks, primarily those associated with the Partnership’s January 2012 acquisition of Heritage Propane, was presented to the Partnership’s senior management. After considering the merits of the plan, the Partnership’s senior management approved a plan to discontinue the use of these tradenames and trademarks over a period of approximately three years . As a result, during the three months ended June 30, 2018, the Partnership determined that these tradenames and trademarks no longer had indefinite lives and, in accordance with GAAP associated with intangible assets, adjusted the carrying amounts of these tradenames and trademarks to their estimated fair values of approximately $7,944 . During the three months ended June 30, 2018, the Partnership recorded a non-cash impairment charge of $75,000 , which amount is reflected in “Impairment of tradenames and trademarks” on the Condensed Consolidated Statements of Operations, and is amortizing the remaining fair value of these tradenames and trademarks of $7,944 over their estimated period of benefit of three years .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 6 — Commitments and Contingencies Contingencies Saranac Lake Environmental Matter. In 2008, the NYDEC notified AmeriGas OLP that the NYDEC had placed property purportedly owned by AmeriGas OLP in Saranac Lake, New York on the New York State Registry of Inactive Hazardous Waste Disposal Sites. A site characterization study performed by the NYDEC disclosed contamination related to a former MGP. AmeriGas OLP responded to the NYDEC in 2009 to dispute the contention it was a PRP as it did not operate the MGP and appeared to only own a portion of the site. In 2017, the NYDEC communicated to AmeriGas OLP that the NYDEC had previously issued three RODs related to remediation of the site totaling approximately $27,700 and requested additional information regarding AmeriGas OLP’s purported ownership. AmeriGas renewed its challenge to designation as a PRP and identified potential defenses. The NYDEC subsequently identified a third party PRP with respect to the site. The NYDEC commenced implementation of the remediation plan in the spring of 2018. Based on our evaluation of the available information, the Partnership accrued an undiscounted environmental remediation liability of $7,545 related to the site during the third quarter of Fiscal 2017. Our share of the actual remediation costs could be significantly more or less than the accrued amount. Purported Class Action Lawsuits. Between May and October of 2014, purported class action lawsuits were filed in multiple jurisdictions against the Partnership/UGI and a competitor by certain of their direct and indirect customers. The class action lawsuits allege, among other things, that the Partnership and its competitor colluded, beginning in 2008, to reduce the fill level of portable propane cylinders from 17 pounds to 15 pounds and combined to persuade their common customer, Walmart Stores, Inc., to accept that fill reduction, resulting in increased cylinder costs to retailers and end-user customers in violation of federal and certain state antitrust laws. The claims seek treble damages, injunctive relief, attorneys’ fees and costs on behalf of the putative classes. On October 16, 2014, the United States Judicial Panel on Multidistrict Litigation transferred all of these purported class action cases to the Western Missouri District Court. As the result of rulings on a series of procedural filings, including petitions filed with the Eighth Circuit and the U.S. Supreme Court, both the federal and state law claims of the direct customer plaintiffs and the state law claims of the indirect customer plaintiffs were remanded to the Western Missouri District Court. The decision of the Western Missouri District Court to dismiss the federal antitrust claims of the indirect customer plaintiffs was upheld by the Eighth Circuit. On April 15, 2019, the Western Missouri District Court ruled that it has jurisdiction over the indirect purchasers’ state law claims and that the indirect customer plaintiffs have standing to pursue those claims. Although we cannot predict the final results of these pending claims and legal actions, we believe, after consultation with counsel, that the final outcome of these matters will not have a material effect on our financial statements. Proposed Merger Lawsuits. In connection with the Proposed Merger (see Note 10), on June 5, 2019, a single AmeriGas Partners unitholder filed a class action complaint in the United States District Court for the District of Delaware. On July 9, 2019, a second AmeriGas Partners unitholder filed a complaint in the United States District Court for the Eastern District of Pennsylvania. The complaints generally allege that the May 6, 2019 registration statement filed with the SEC in connection with the Proposed Merger included materially incomplete and/or misleading information in violation of the federal securities laws. The complaints request, among other things, that the respective courts enjoin the parties from proceeding with the Proposed Merger or rescind the Proposed Merger if it does close. Both plaintiffs seek an award of attorneys’ fees and costs. AmeriGas Partners has not yet answered or responded to the complaints. Although we cannot predict the final results of these pending claims and legal actions, we believe, after consultation with counsel, that the final outcome of these matters will not have a material effect on our financial statements. In addition to the matters described above, there are other pending claims and legal actions arising in the normal course of our businesses. Although we cannot predict the final results of these pending claims and legal actions, we believe, after consultation with counsel, that the final outcome of these matters will not have a material effect on our financial statements.

Fair Value Measurements	Note 7 — Fair Value Measurements Recurring Fair Value Measurements - Derivative Instruments The following table presents, on a gross basis, our derivative assets and liabilities, including both current and noncurrent portions, that are measured at fair value on a recurring basis within the fair value hierarchy: Asset (Liability) Level 1 Level 2 Level 3 Total June 30, 2019: Assets: Commodity contracts $ — $ 7,428 $ — $ 7,428 Liabilities: Commodity contracts $ — $ (19,995 ) $ — $ (19,995 ) September 30, 2018: Assets: Commodity contracts $ — $ 52,529 $ — $ 52,529 Liabilities: Commodity contracts $ — $ (251 ) $ — $ (251 ) June 30, 2018: Assets: Commodity contracts $ — $ 30,086 $ — $ 30,086 Liabilities: Commodity contracts $ — $ (420 ) $ — $ (420 ) The fair values of our non-exchange traded commodity derivative contracts included in Level 2 are based upon indicative price quotations available through brokers, industry price publications or recent market transactions and related market indicators. Other Financial Instruments The carrying amounts of other financial instruments included in current assets and current liabilities (except for current maturities of long-term debt) approximate their fair values because of their short-term nature. We estimate the fair value of long-term debt by using current market rates and by discounting future cash flows using rates available for similar type debt (Level 2). The carrying amount and estimated fair value of our long-term debt (including current maturities but excluding unamortized debt issuance costs) at June 30, 2019 , September 30, 2018 and June 30, 2018 were as follows: June 30, 2019 September 30, 2018 June 30, 2018 Carrying amount $ 2,593,504 $ 2,597,131 $ 2,602,827 Estimated fair value $ 2,724,645 $ 2,562,206 $ 2,519,411 Financial instruments other than derivative instruments, such as short-term investments and trade accounts receivable, could expose us to concentrations of credit risk. We limit credit risk from short-term investments by investing only in investment-grade commercial paper, money market mutual funds, securities guaranteed by the U.S. Government or its agencies and FDIC insured bank deposits. The credit risk arising from concentrations of trade accounts receivable is limited because we have a large customer base that extends across many different U.S. markets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Note 8 — Derivative Instruments and Hedging Activities The Partnership is exposed to certain market risks associated with its ongoing business operations. Management uses derivative financial and commodity instruments, among other things, to manage these risks. The primary risk managed by derivative instruments is commodity price risk. Although we use derivative financial and commodity instruments to reduce market risk associated with forecasted transactions, we do not use derivative financial and commodity instruments for speculative or trading purposes. The use of derivative instruments is controlled by our risk management and credit policies which govern, among other things, the derivative instruments the Partnership can use, counterparty credit limits and contract authorization limits. Although our commodity derivative instruments extend over a number of years, a significant portion of our commodity derivative instruments economically hedge commodity price risk during the next twelve months. Commodity Price Risk In order to manage market risk associated with the Partnership’s fixed-price programs, the Partnership uses over-the-counter derivative commodity instruments, principally price swap contracts, to reduce propane price volatility associated with a portion of forecasted propane purchases. In addition, the Partnership from time to time enters into price swap agreements to reduce the effects of short term commodity price volatility. At June 30, 2019 , September 30, 2018 and June 30, 2018 , total volumes associated with propane commodity derivatives totaled 399.5 million gallons, 244.8 million gallons and 226.6 million gallons, respectively. At June 30, 2019 , the maximum period over which we are economically hedging propane market price risk is 27 months . Derivative Instruments Credit Risk The Partnership is exposed to credit loss in the event of nonperformance by counterparties to derivative financial and commodity instruments. Our counterparties principally comprise major energy companies and major U.S. financial institutions. We maintain credit policies with regard to our counterparties that we believe reduce overall credit risk. These policies include evaluating and monitoring our counterparties’ financial condition, including their credit ratings, and entering into agreements with counterparties that govern credit limits. Certain of these agreements call for the posting of collateral by the counterparty or by the Partnership in the forms of letters of credit, parental guarantees or cash. Although we have concentrations of credit risk associated with derivative instruments held by certain derivative instrument counterparties, the maximum amount of loss due to credit risk that, based upon the gross fair values of the derivative instruments, we would incur if these counterparties that make up the concentration failed to perform according to the terms of their contracts was not material at June 30, 2019 . Certain of our derivative contracts have credit-risk-related contingent features that may require the posting of additional collateral in the event of a downgrade in the Partnership’s debt rating. At June 30, 2019 , if the credit-risk-related contingent features were triggered, the amount of collateral required to be posted would not be material. Offsetting Derivative Assets and Liabilities Derivative assets and liabilities are presented net by counterparty on the Consolidated Balance Sheets if the right of offset exists. Our derivative instruments comprise over-the-counter transactions. Over-the-counter contracts are bilateral contracts that are transacted directly with a third party. Certain over-the-counter contracts contain contractual rights of offset through master netting arrangements and contract default provisions. In addition, the contracts are subject to conditional rights of offset through counterparty nonperformance, insolvency, or other conditions. In general, most of our over-the-counter transactions are subject to collateral requirements. Types of collateral generally include cash or letters of credit. Cash collateral paid by us to our over-the-counter derivative counterparties, if any, is reflected in the table below to offset derivative liabilities. Cash collateral received by us from our over-the-counter derivative counterparties, if any, is reflected in the table below to offset derivative assets. Certain other accounts receivable and accounts payable balances recognized on the Consolidated Balance Sheets with our derivative counterparties are not included in the table below but could reduce our net exposure to such counterparties because such balances are subject to master netting or similar arrangements. Fair Value of Derivative Instruments The following table presents our derivative assets and liabilities by type, as well as the effects of offsetting: June 30, September 30, June 30, Derivative assets not designated as hedging instruments: Commodity contracts $ 7,428 $ 52,529 $ 30,086 Total derivative assets — gross 7,428 52,529 30,086 Gross amounts offset in the balance sheet (2,497 ) (251 ) (420 ) Cash collateral received — (7,270 ) — Total derivative assets — net $ 4,931 $ 45,008 $ 29,666 Derivative liabilities not designated as hedging instruments: Commodity contracts $ (19,995 ) $ (251 ) $ (420 ) Total derivative liabilities — gross (19,995 ) (251 ) (420 ) Gross amounts offset in the balance sheet 2,497 251 420 Cash collateral pledged 2,320 — — Total derivative liabilities — net (a) $ (15,178 ) $ — $ — (a) Derivative liabilities with maturities greater than one year are recorded in “ Other noncurrent liabilities ” on the Condensed Consolidated Balance Sheets.

These contracts include, among others, binding purchase orders, contracts that provide for the purchase and delivery of propane and service contracts that require the counterparty to provide commodity storage or transportation service to meet our normal sales commitments. Although certain of these contracts have the requisite elements of a derivative instrument, these contracts qualify for NPNS accounting under GAAP because they provide for the delivery of products or services in quantities that are expected to be used in the normal course of operating our business and the price in the contract is based on an underlying that is directly associated with the price of the product or service being purchased or sold.

Related Party Transactions [Abstract]
Related Party Transactions	Note 9 — Related Party Transactions Pursuant to the Partnership Agreement and a management services agreement, the General Partner is entitled to reimbursement for all direct and indirect expenses incurred or payments it makes on behalf of the Partnership. These costs, which totaled $137,069 and $134,986 for the three months ended June 30, 2019 and 2018 , respectively, and $446,034 and $439,386 for the nine months ended June 30, 2019 and 2018 , respectively, include employee compensation and benefit expenses of employees of the General Partner and general and administrative expenses. UGI provides certain financial and administrative services to the General Partner. UGI bills the General Partner monthly for all direct and indirect corporate expenses incurred in connection with providing these services and the General Partner is reimbursed by the Partnership for these expenses. The allocation of indirect UGI corporate expenses to the Partnership utilizes a weighted, three-component formula based on the relative percentage of the Partnership’s revenues, operating expenses and net assets employed to the total of such items for all UGI operating subsidiaries for which general and administrative services are provided. The General Partner believes that this allocation method is reasonable and equitable to the Partnership. Such corporate expenses totaled $3,493 and $4,979 for the three months ended June 30, 2019 and 2018 , respectively, and $12,473 and $12,997 for the nine months ended June 30, 2019 and 2018 , respectively. In addition, UGI and certain of its subsidiaries provide office space, stop loss medical coverage and automobile liability insurance to the Partnership. The costs incurred related to these items during the three and nine months ended June 30, 2019 and 2018 , were not material. From time to time, AmeriGas OLP purchases propane on an as needed basis from Energy Services. The price of the purchases is generally based on market price at the time of purchase. Purchases of propane by AmeriGas OLP from Energy Services during the three and nine months ended June 30, 2019 and 2018 were not material. In addition, the AmeriGas OLP sells propane to affiliates of UGI. Sales of propane to affiliates of UGI during three and nine months ended June 30, 2019 and 2018 were no t material. UGI Standby Commitment to Purchase AmeriGas Partners Class B Common Units On November 7, 2017, AmeriGas Partners entered into a Standby Equity Commitment Agreement with the General Partner and UGI. Under the terms of the Standby Equity Commitment Agreement, upon the request of AmeriGas Partners from time to time, in each instance only with prior approval by the General Partner Audit Committee, which would be made in its sole and absolute discretion, UGI committed to make up to $225,000 of capital contributions to the Partnership through July 1, 2019. Under the terms of the Commitment Agreement, the last date on which AmeriGas Partners could have requested a capital contribution, without the consent of UGI, was May 17, 2019. AmeriGas Partners did not request, and UGI did not make, any capital contributions under the Commitment Agreement and the agreement has now terminated in accordance with its terms.

Proposed Merger	Note 10 — Proposed Merger On April 1, 2019, we entered into the Merger Agreement, pursuant to which Merger Sub will merge with and into the Partnership, with the Partnership surviving as an indirect, wholly owned subsidiary of UGI. Under the terms of the Merger Agreement, at the effective time of the Proposed Merger, each outstanding Common Unit other than Common Units owned by UGI and its subsidiaries, including the General Partner, will be converted into the right to receive, at the election of each holder of such Common Units, one of the following forms of merger consideration: (i) 0.6378 shares of UGI common stock; (ii) $7.63 in cash, without interest, and 0.500 shares of UGI common stock; or (iii) $35.325 in cash, without interest. The merger consideration is subject to proration designed to ensure that the total number of shares of UGI common stock issuable as merger consideration will equal approximately 34.6 million shares, and the amount of cash consideration paid will equal approximately $530,000 . Also, at the effective time of the Proposed Merger, the General Partner’s 1% economic general partner interest in AmeriGas Partners, which includes its incentive distribution rights, will convert into (i) 10,615,711 Common Units, which will remain outstanding as partnership interests in AmeriGas Partners, and (ii) a non-economic general partner interest in AmeriGas Partners. Pursuant to the Merger Agreement, until such time as the Proposed Merger becomes effective, the General Partner will continue to declare and cause to be paid regular quarterly cash distributions on outstanding Common Units in accordance with the Partnership Agreement in an amount that will not be less than $0.95 per Common Unit. In addition, the Merger Agreement requires that the record date for the quarterly cash distribution related to the quarter immediately prior to the quarter in which the closing of the Proposed Merger occurs be designated so that such record date precedes the closing of the Proposed Merger so as to permit the payment of such quarterly distribution to the holders of the Common Units; provided that the AmeriGas Partners’ unitholders are not intended to receive, for any quarter, distributions both in respect of Common Units and also dividends in respect of shares of UGI common stock that they receive in exchange for such Common Units in the transaction. Completion of the Proposed Merger is subject to certain customary conditions, including, among others: (i) approval of the Merger Agreement by holders of a majority of the outstanding Common Units; (ii) there being no law or injunction prohibiting consummation of the transactions contemplated under the Merger Agreement; (iii) the effectiveness of a registration statement on Form S-4 relating to the issuance of shares of UGI common stock pursuant to the Merger Agreement; (iv) approval for listing on the New York Stock Exchange of the shares of UGI common stock issuable pursuant to the Merger Agreement; (v) subject to specified materiality standards, the accuracy of certain representations and warranties of the other party; and (vi) compliance by the respective parties in all material respects with their respective covenants. UGI’s registration statement on Form S-4 relating to the Proposed Merger became effective July 12, 2019. Pursuant to a Support Agreement, the General Partner has agreed to vote all Partnership Common Units that it or its affiliates beneficially own as of the record date of the Special Meeting in favor of the Merger Agreement and the Proposed Merger. The Merger Agreement provides for certain termination rights for both UGI and the Partnership which, under certain circumstances, would require the Partnership to pay UGI a termination fee of $20,000 and/or reimburse UGI for expenses in an amount not to exceed $5,000 or require UGI to reimburse the Partnership for expenses not to exceed $5,000 .

The General Partner of AmeriGas OLP, which is also the General Partner of AmeriGas Partners, makes all decisions for AmeriGas OLP; limited partners of AmeriGas OLP do not have the ability to remove the General Partner or participate in the decision-making for AmeriGas OLP. The accounts of AmeriGas OLP are included based upon the determination that AmeriGas Partners has a controlling financial interest in and is the primary beneficiary of AmeriGas OLP. We eliminate intercompany accounts and transactions when we consolidate.
Revenue Recognition	Revenue Recognition. Effective October 1, 2018, the Partnership adopted ASU No. 2014-09, “Revenue from Contracts with Customers,” which, as amended, is included in ASC 606. This new accounting guidance supersedes previous revenue recognition requirements in ASC 605. ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The Partnership adopted this new accounting guidance using the modified retrospective transition method to those contracts which were not completed as of October 1, 2018. Periods prior to October 1, 2018, have not been restated and continue to be reported in accordance with ASC 605. Upon adoption, there were no cumulative effect adjustments made to the October 1, 2018, partners’ capital balances. The adoption of ASC 606 did not, and is not expected to, have a material impact on the amount or timing of our revenue recognition and on our consolidated net income, cash flows or financial position. Certain revenues are not within the scope of ASC 606 such as revenue from leases, financial instruments, other revenues that are not from contracts with customers, and other contractual rights or obligations and we account for such revenues in accordance with other GAAP. Revenue-related taxes collected on behalf of customers and remitted to taxing authorities, principally sales and use taxes, are not included in revenues. The Partnership has elected to use the practical expedient to expense the costs to obtain contracts when incurred as such amounts are generally not material.
Allocation of Net Income (Loss)	Allocation of Net Income (Loss) . Net income (loss) attributable to AmeriGas Partners, L.P. for partners’ capital and statement of operations presentation purposes is allocated to the General Partner and the limited partners in accordance with their respective ownership percentages after giving effect to amounts distributed to the General Partner in excess of its 1% general partner interest in AmeriGas Partners based on its IDRs under the Partnership Agreement.
Income (Loss) Per Unit	Income (Loss) Per Unit. Income (loss) per limited partner unit is computed in accordance with GAAP regarding the application of the two-class method for determining income (loss) per unit for MLPs when IDRs are present. The two-class method requires that income per limited partner unit be calculated as if all earnings for the period were distributed and requires a separate calculation for each quarter and year-to-date period. In periods when our net income attributable to AmeriGas Partners exceeds our Available Cash, as defined in the Partnership Agreement, and is above certain levels, the calculation according to the two-class method results in an increased allocation of undistributed earnings to the General Partner. Generally, in periods when our Available Cash in respect of the quarter or year-to-date periods exceeds our net income (loss) attributable to AmeriGas Partners, the calculation according to the two-class method results in an allocation of earnings to the General Partner greater than its relative ownership interest in the Partnership (or in the case of a net loss attributable to AmeriGas Partners, an allocation of such net loss to the Common Unitholders greater than their relative ownership interest in the Partnership).
Derivative Instruments	Derivative Instruments. Derivative instruments are reported on the Condensed Consolidated Balance Sheets at their fair values, unless the NPNS exception is elected. The accounting for changes in fair value depends upon the purpose of the derivative instrument and whether it qualifies and is designated as a hedge for accounting purposes. We do not currently have derivative instruments that are designated and qualify as cash flow hedges. Changes in the fair values of our commodity derivative instruments are reflected in “Cost of sales — propane” on the Condensed Consolidated Statements of Operations. Cash flows from commodity derivative instruments are included in cash flows from operating activities on the Condensed Consolidated Statements of Cash Flows.
Use of Estimates	Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and costs. These estimates are based on management’s knowledge of current events, historical experience and various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may be different from these estimates and assumptions.
Reclassifications	Reclassifications.
New Accounting Standards Adopted Effective October 1, 2018 and Accounting Standards Not Yet Adopted	New Accounting Standards Adopted Effective October 1, 2018 Revenue Recognition. Effective October 1, 2018, the Partnership adopted new accounting guidance regarding revenue recognition. See Notes 2 and 4 for a detailed description of the impact of the new guidance and related disclosures. Cloud Computing Implementation Costs. In August 2018, the FASB issued ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” The new guidance requires a customer in a cloud computing arrangement that is a service contract to capitalize certain implementation costs as if the arrangement was an internal-use software project. These deferred implementation costs are expensed over the fixed, noncancelable term of the service arrangement plus any reasonably certain renewal periods. The new guidance also requires the entity to present the expense related to the capitalized implementation costs in the same income statement line as the hosting service fees; to classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments for hosting service fees; and to present the capitalized implementation costs in the balance sheet in the same line item in which prepaid hosting service fees are presented. The new guidance can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We adopted this ASU effective October 1, 2018, and applied the guidance prospectively to all implementation costs associated with cloud computing arrangements that are service contracts incurred beginning October 1, 2018. The adoption of the new guidance did not have a material impact on our results of operations for the three and nine months ended June 30, 2019 . Accounting Standards Not Yet Adopted Fair Value Measurements Disclosures. In August 2018, the FASB issued ASU No. 2018-13, “Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The amendments in this ASU are effective for annual periods beginning October 1, 2020 (Fiscal 2021). The guidance regarding removing and modifying disclosures will be adopted on a retrospective basis and the guidance regarding new disclosures will be adopted on a prospective basis. Early adoption is permitted. The Partnership expects to adopt the new guidance in the fourth quarter of Fiscal 2019. The adoption of the new guidance is not expected to have a material impact on the Partnership’s financial statements. Derivatives and Hedging. In August 2017, the FASB issued ASU No. 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” This ASU amends and simplifies existing guidance to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The amendments in this ASU are effective for the Partnership for interim and annual periods beginning October 1, 2019 (Fiscal 2020). Early adoption is permitted. For cash flow and net investment hedges as of the adoption date, the guidance requires a modified retrospective approach. The amended presentation and disclosure guidance is required prospectively. The Partnership expects to adopt the new guidance in the first quarter of Fiscal 2020. The adoption of the new guidance is not expected to have a material impact on the Partnership’s financial statements. Credit Losses. In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments. ” This ASU requires entities to estimate lifetime expected credit losses for financial instruments not measured at fair value through net income, including trade and other receivables, net investments in leases, financial receivables, debt securities, and other financial instruments, which may result in earlier recognition of credit losses. Further, the new current expected credit loss model may affect how entities estimate their allowance for loss for receivables that are current with respect to their payment terms. ASU 2016-13 is effective for the Partnership for interim and annual periods beginning October 1, 2020 (Fiscal 2021). Early adoption is permitted. The Partnership is in the process of assessing the impact on its financial statements from the adoption of the new guidance and determining the period in which the new guidance will be adopted. Leases. In February 2016, the FASB issued ASU No. 2016-02, "Leases." This ASU, as subsequently updated, amends existing guidance to require entities that lease assets to recognize the assets and liabilities for the rights and obligations created by those leases on the balance sheet. The new guidance also requires additional disclosures about the amount, timing and uncertainty of cash flows from leases. The amendments in this ASU are effective for the Partnership for interim and annual periods beginning October 1, 2019 (Fiscal 2020). Early adoption is permitted. Lessees must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements unless an entity chooses the transition option in ASU 2018-11, “Leases: Targeted Improvements” which, among other things, provides entities with a transition option to recognize the cumulative-effect adjustment from the modified retrospective application to the opening balance of retained earnings in the period of adoption. We will adopt ASU No. 2016-02, as updated, effective October 1, 2019 and expect to elect the transition option which would allow the Partnership to maintain historical presentation for periods before October 1, 2019. The Partnership has completed a preliminary assessment for evaluating the impact of the guidance and anticipates that its adoption will result in a significant amount of right-of-use assets and lease liabilities for leases in effect at the adoption date. The Partnership has begun implementation activities including accumulating contracts and lease data in formats compatible with a new lease management system that will assist with the initial adoption and future reporting required by the standard.
