	Nature of Operations
	AmeriGas Partners, L.P. (“AmeriGas Partners”) is a publicly traded limited partnership that conducts a national propane distribution business through its principal operating subsidiary AmeriGas Propane, L.P. (“AmeriGas OLP”) and prior to its merger with AmeriGas OLP on July 1, 2013 (the “Merger”), AmeriGas OLP’s principal operating subsidiary Heritage Operating, L.P. (“HOLP”). AmeriGas OLP after the Merger, and AmeriGas OLP and HOLP prior to the Merger, are referred to herein as the “Operating Partnership.” AmeriGas Partners and AmeriGas OLP are Delaware limited partnerships. AmeriGas Partners, the Operating Partnership and its subsidiaries are collectively referred to herein as the “Partnership” or “we.”
	The Operating Partnership is engaged in the distribution of propane and related equipment and supplies. The Operating Partnership 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 March 31, 2014, AmeriGas Propane, Inc. (the “General Partner”), an indirect wholly owned subsidiary of UGI Corporation (“UGI”), held a 1% general partner interest in AmeriGas Partners and a 1.01% general partner interest in AmeriGas OLP. The General Partner and its wholly owned subsidiary Petrolane Incorporated (“Petrolane,” a predecessor company of the Partnership) also owned 23,756,882 AmeriGas Partners Common Units (“Common Units”). The remaining Common Units outstanding at March 31, 2014, comprise 69,109,914 publicly held Common Units of which 12,867,362 Common Units are held by a subsidiary of Energy Transfer Partners, L.P. (“ETP”) as a result of the January 12, 2012, acquisition of substantially all of ETP’s propane operations (the “Heritage Acquisition”). The Common Units represent limited partner interests in AmeriGas Partners. AmeriGas Partners holds a 98.99% limited partner interest in AmeriGas OLP. In January 2014, ETP sold 9,200,000 of the Common Units it held in an underwritten public offering, pursuant to its registration rights in its unitholder agreement. AmeriGas Partners did not receive any proceeds from the sale of the Common Units by ETP.
	AmeriGas Partners and the Operating Partnership have no employees. Employees of the General Partner conduct, direct and manage our operations. Prior to the Merger, the General Partner provided management and administrative services to Heritage Operating GP, LLC (“HOLP GP”), the general partner of HOLP, under a management services agreement. The General Partner is reimbursed monthly for all direct and indirect expenses it incurs on our behalf (see Note 5).

	Significant Accounting Policies
	The condensed consolidated financial statements include the accounts of AmeriGas Partners, its majority-owned subsidiary AmeriGas OLP, and its 100%-owned finance subsidiaries AmeriGas Finance Corp., AP Eagle Finance Corp. and AmeriGas Finance, LLC. The accounts of AmeriGas Partners’ majority-owned subsidiary AmeriGas OLP are included based upon the determination that, given the Partnership’s structure, AmeriGas Partners will absorb a majority of AmeriGas OLP’s expected losses, will receive a majority of AmeriGas OLP’s expected residual returns, and is AmeriGas OLP’s primary beneficiary. AmeriGas OLP includes the accounts of its wholly owned subsidiaries. We eliminate all significant intercompany accounts and transactions when we consolidate. We account for the General Partner’s 1.01% interest in AmeriGas OLP as noncontrolling interest in the condensed consolidated financial statements.
	AmeriGas Finance Corp., AP Eagle Finance Corp. and AmeriGas Finance LLC are 100%-owned finance subsidiaries of AmeriGas Partners. Their sole purpose is to serve as issuers or co-obligors for debt securities issued or guaranteed by AmeriGas Partners. The 6.75% and 7.00% Senior Notes were co-issued by AmeriGas Finance Corp. and AmeriGas Finance LLC and are fully and unconditionally guaranteed on a senior unsecured basis by AmeriGas Partners.
	The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“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, 2013, condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).
	These financial statements should be read in conjunction with the financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2013 (“Partnership’s 2013 Annual Financial Statements and Notes”). 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.
	Allocation of Net Income Attributable to AmeriGas Partners. Net income 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 incentive distribution rights (“IDRs”) under the Fourth Amended and Restated Agreement of Limited Partnership of AmeriGas Partners, as amended (“Partnership Agreement”).
	Net Income Per Unit. Income per limited partner unit is computed in accordance with GAAP regarding the application of the two-class method for determining income per unit for master limited partnerships (“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						Six Months Ended
		March 31,						March 31,
		2014			2013			2014			2013
	Net income attributable to AmeriGas Partners, L.P.	$	240,103		$	213,208		$	375,001		$	309,873
	Adjust for theoretical distributions of net income attributable to AmeriGas Partners, L.P. to the general partner in accordance with the two-class method for MLPs	(81,389		)	(68,099		)	(110,727		)	(78,523		)
	Common Unitholders’ interest in net income attributable to AmeriGas Partners, L.P. under the two-class method for MLPs	$	158,714		$	145,109		$	264,274		$	231,350
	Weighted average Common Units outstanding—basic (thousands)	92,883			92,830			92,867			92,827
	Potentially dilutive Common Units (thousands)	51			65			73			74
	Weighted average Common Units outstanding—diluted (thousands)	92,934			92,895			92,940			92,901
	Theoretical distributions of net income attributable to AmeriGas Partners, L.P. in accordance with the two-class method for the three months ended March 31, 2014 and 2013, resulted in an increased allocation of net income attributable to AmeriGas Partners, L.P. to the General Partner in the computation of income per limited partner unit which had the effect of decreasing earnings per limited partner unit by $0.79 and $0.66, respectively. Theoretical distributions of net income attributable to AmeriGas Partners, L.P. in accordance with the two-class method for the six months ended March 31, 2014 and 2013, resulted in an increased allocation of net income attributable to AmeriGas Partners, L.P. to the General Partner in the computation of income per limited partner unit which had the effect of decreasing earnings per limited partner unit by $1.04 and $0.72, respectively.
	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.
	Comprehensive Income. Comprehensive income comprises net income and other comprehensive income. Other comprehensive income principally results from gains and losses on derivative instruments qualifying as cash flow hedges, net of reclassifications to net income. For information regarding the amounts and line items on the Condensed Consolidated Statements of Operations associated with reclassification from accumulated other comprehensive income (“AOCI”), see Note 8.
	Reclassifications. Certain prior period amounts have been reclassified to conform to current period presentation.
	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.

	Accounting Changes
	Adoption of New Accounting Standards
	Disclosures about Reclassifications Out of Accumulated Other Comprehensive Income. During the three months ended December 31, 2013, the Partnership adopted new accounting guidance regarding disclosures for items reclassified out of AOCI. The disclosures required by the new accounting guidance are included in the notes to the condensed consolidated financial statements. The new disclosures are applied prospectively. As this guidance only affects disclosure requirements, the adoption of this guidance did not impact our results of operations, cash flows or financial position.
	Disclosures about Offsetting Assets and Liabilities. During the three months ended December 31, 2013, the Partnership adopted new accounting guidance requiring entities to disclose both gross and net information about recognized derivative instruments that are offset on the balance sheet as a result of an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset on the balance sheet. The new disclosures are applied retroactively for all periods presented. The required disclosures are included in Note 7 to the condensed consolidated financial statements. As this guidance only affects disclosure requirements, the adoption of this guidance did not impact our results of operations, cash flows or financial position.

	Pursuant to the Partnership Agreement and, prior to the Merger, a management services agreement among HOLP GP, HOLP and the General Partner, the General Partner is entitled to reimbursement for all direct and indirect expenses incurred or payments it makes on our behalf. These costs, which totaled $155,414 and $150,705 for the three months ended March 31, 2014 and 2013, respectively, and $299,950 and $290,502 for six months ended March 31, 2014 and 2013, 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 $7,463 and $6,864, during the three months ended March 31, 2014 and 2013, respectively, and $10,957 and $10,756 during the six months ended March 31, 2014 and 2013, 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 related to these items totaled $1,084 and $1,062 for the three months ended March 31, 2014 and 2013, respectively, and $2,215 and $2,626 for the six months ended March 31, 2014 and 2013, respectively.
	From time to time, AmeriGas OLP purchases propane on an as needed basis from UGI Energy Services, Inc. (“Energy Services”). In addition, the Partnership sells propane to Energy Services and certain other affiliates of UGI. Such amounts were not material during the periods presented.

	Federal Trade Commission Investigation of Propane Grill Cylinder Filling Practices. On or about November 4, 2011, the General Partner received notice that the Federal Trade Commission (“FTC”) had initiated an antitrust and consumer protection investigation into certain practices of the Partnership which relate to the filling of portable propane cylinders. On February 2, 2012, the Partnership received a Civil Investigative Demand from the FTC that requested documents and information concerning, among other things, (i) the Partnership’s decision, in 2008, to reduce the volume of propane in cylinders it sells to consumers from 17 pounds to 15 pounds, and (ii) cross-filling, related service arrangements and communications regarding the foregoing with competitors. The Partnership responded to that subpoena and cooperated with subsequent requests for information. On March 27, 2014, the FTC issued an administrative complaint against the Partnership and UGI alleging that the General Partner and one of its competitors colluded in 2008 to persuade its joint customer, Walmart Stores, Inc., to accept the cylinder fill reduction from 17 pounds to 15 pounds.  The complaint does not seek monetary remedies.  The Partnership and UGI filed their Answer to the complaint on April 18, 2014 and believe that they have good defenses to the FTC’s claims.  We are unable to reasonably estimate the impact, if any, arising from this claim.
	In addition to the matter 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 consolidated financial position, results of operations or cash flows.

	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. For commodity option contracts not traded on an exchange, we use a Black Scholes option pricing model that considers time value and volatility of the underlying commodity.
	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. At March 31, 2014, the carrying amount and estimated fair value of our long-term debt (including current maturities) were $2,296,039 and $2,482,558, respectively. At March 31, 2013, the carrying amount and estimated fair value of our long-term debt (including current maturities) were $2,320,381 and $2,504,903, respectively. We estimate the fair value of long-term debt by using current market prices and by discounting future cash flows using rates available for similar type debt (Level 2).
	We have financial instruments such as short-term investments and trade accounts receivable which could expose us to concentrations of credit risk. We limit our credit risk from short-term investments by investing only in investment-grade commercial paper and U.S. Government securities. The credit risk from trade accounts receivable is limited because we have a large customer base which extends across many different U.S. markets.
	Disclosures about Offsetting Derivative Assets and Liabilities
	Derivative assets and liabilities are presented net by counterparty on our Condensed Consolidated Balance Sheets if the right of offset exists. Our derivative financial instruments principally comprise propane over-the-counter swap and option contracts. 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, contracts may be 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. Any cash collateral paid by us to our derivative counterparties is reflected in the table below to offset derivative liabilities. Any cash collateral received by us from our counterparties is reflected in the table below to offset derivative assets. Certain other accounts receivable and accounts payable balances recognized on our Condensed Consolidated Balance Sheets with our derivative counterparties are not included in the tables below but would reduce our net exposure to such counterparties because they are subject to master netting or similar arrangements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Disclosures About Derivative Instruments and Hedging Activities	'
	Disclosures about Derivative Instruments and Hedging Activities
	The Partnership is exposed to certain market risks related to its ongoing business operations. Management uses derivative financial and commodity instruments, among other things, to manage these risks. The primary risk currently managed by derivative instruments is commodity price risk for propane. 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. Because a substantial portion of our derivative instruments generally qualify as hedges under GAAP, we expect that changes in the fair value of derivative instruments used to manage commodity or interest rate market risk would be substantially offset by gains or losses on the associated anticipated transactions.
	Commodity Price Risk
	In order to manage market risk associated with the Partnership’s fixed-price programs, which permit customers to lock in the prices they pay for propane principally during the months of October through March, the Partnership uses over-the-counter derivative commodity instruments, principally price swap and option contracts. At March 31, 2014 and 2013, there were 110.0 million gallons and 121.3 million gallons, respectively, of propane hedged with over-the-counter price swap and option contracts. At March 31, 2014, the maximum period over which we are hedging propane market price risk is 18 months with a weighted average of 7 months. In addition, the Partnership from time to time enters into price swap and option agreements to reduce short-term commodity price volatility which are generally not designated as hedges for accounting purposes.
	During the periods presented in the financial statements, we accounted for a significant portion of our commodity price risk contracts as cash flow hedges. Changes in the fair values of contracts qualifying for cash flow hedge accounting are recorded in AOCI and noncontrolling interest, to the extent effective in offsetting changes in the underlying commodity price risk, until earnings are affected by the hedged item. At March 31, 2014, the amount of net gains associated with commodity price risk hedges expected to be reclassified into earnings during the next twelve months based upon current fair values is $11,448.
	Derivative Financial 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 consist of 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. We have concentrations of credit risk associated with derivative financial instruments held by certain derivative financial instrument counterparties. Although we have concentrations of credit risk, the maximum amount of loss due to credit risk that we would incur if these counterparties comprising the concentration failed to perform according to the terms of their contracts was not material at March 31, 2014, based upon the fair values of such derivative instruments. 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 March 31, 2014, if the credit-risk-related contingent features were triggered, the amount of collateral required to be posted would not be material.
	The following table provides information regarding the fair values and balance sheet locations of our derivative assets and liabilities existing as of March 31, 2014 and 2013:

Although many of these contracts have the requisite elements of a derivative instrument, these contracts qualify for normal purchase and normal sales exception 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.

Accounting Changes and Error Corrections	'
	Error in Accounting for Certain Customer Credits
	During the three months ended March 31, 2013, the Partnership identified an error in its accounting for certain customer credits. The Partnership determined that the recording of propane revenues did not appropriately consider the effects of certain customer credits which were recorded when issued in a subsequent period. As a result, the Partnership changed its accounting for customer credits to record an estimate of such credits at the time propane revenues are recorded. Such estimate considers the Partnership’s history of providing credits, propane revenue activity and other factors. During the three months ended March 31, 2013, 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 or six months ended March 31, 2013, or any prior period financial statement and recorded the cumulative effect of the error in accounting for customer credits as of January 1, 2013, which decreased accounts receivable and propane revenues by $7,038 and decreased net income attributable to AmeriGas Partners, L.P. for the three and six months ended March 31, 2013, by $6,967.

Allocation of Net Income Attributable to AmeriGas Partners	'
	Allocation of Net Income Attributable to AmeriGas Partners. Net income 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 incentive distribution rights (“IDRs”) under the Fourth Amended and Restated Agreement of Limited Partnership of AmeriGas Partners, as amended (“Partnership Agreement”).
Net Income Per Unit	'
	Net Income Per Unit. Income per limited partner unit is computed in accordance with GAAP regarding the application of the two-class method for determining income per unit for master limited partnerships (“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:

	Theoretical distributions of net income attributable to AmeriGas Partners, L.P. in accordance with the two-class method for the three months ended March 31, 2014 and 2013, resulted in an increased allocation of net income attributable to AmeriGas Partners, L.P. to the General Partner in the computation of income per limited partner unit which had the effect of decreasing earnings per limited partner unit by $0.79 and $0.66, respectively. Theoretical distributions of net income attributable to AmeriGas Partners, L.P. in accordance with the two-class method for the six months ended March 31, 2014 and 2013, resulted in an increased allocation of net income attributable to AmeriGas Partners, L.P. to the General Partner in the computation of income per limited partner unit which had the effect of decreasing earnings per limited partner unit by $1.04 and $0.72, respectively.
	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.
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.
