Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements include the accounts of PHI, Inc. and its subsidiaries (“PHI” or the “Company” or “we” or “our”). In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting of only normal, recurring adjustments, necessary to present fairly the financial results for the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 and the accompanying notes. Our financial results, particularly as they relate to our Oil and Gas segment, are influenced by seasonal fluctuations as discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. For this and other reasons, the results of operations for interim periods are not necessarily indicative of the operating results that may be expected for a full fiscal year.

Investments, Debt and Equity Securities [Abstract]
Investments	2. INVESTMENTS We classify all of our short-term investments as available-for-sale. We carry these at fair value and report unrealized gains and losses, net of taxes, in Accumulated other comprehensive loss (income), which is a separate component of shareholders’ equity in our Condensed Consolidated Balance Sheets. These unrealized gains and losses are also reflected in our Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Shareholders’ Equity. We determine cost, gains, and losses using the specific identification method. Investments consisted of the following as of March 31, 2016: Cost Basis Unrealized Unrealized Fair Value (Thousands of dollars) Investments: Money market mutual funds $ 17,877 $ — $ — $ 17,877 Commercial paper 5,994 1 — 5,995 U.S. Government agencies 27,301 7 (6 ) 27,302 Corporate bonds and notes 250,399 94 (192 ) 250,301 Subtotal 301,571 102 (198 ) 301,475 Deferred compensation plan assets included in other assets 2,334 — — 2,334 Total $ 303,905 $ 102 $ (198 ) $ 303,809 Investments consisted of the following as of December 31, 2015: Cost Basis Unrealized Unrealized Fair Value (Thousands of dollars) Investments: Money market mutual funds $ 18,181 $ — $ — $ 18,181 Commercial paper 5,986 — (5 ) 5,981 U.S. Government agencies 11,499 — (30 ) 11,469 Corporate bonds and notes 265,069 — (841 ) 264,228 Subtotal 300,735 — (876 ) 299,859 Deferred compensation plan assets included in other assets 2,294 — — 2,294 Total $ 303,029 $ — $ (876 ) $ 302,153 At March 31, 2016 and December 31, 2015, we classified $15.3 million of our aggregate investments as long-term investments and recorded them in our Condensed Consolidated Balance Sheets as Restricted investments, as they are securing outstanding letters of credit with maturities beyond one year. The following table presents the cost and fair value of our debt investments based on maturities as of: March 31, 2016 December 31, 2015 Amortized Fair Value Amortized Fair Value (Thousands of dollars) Due in one year or less $ 148,590 $ 148,516 $ 152,444 $ 152,212 Due within two years 135,104 135,082 130,110 129,466 Total $ 283,694 $ 283,598 $ 282,554 $ 281,678 The following table presents the average coupon rate percentage and the average days to maturity of our debt investments as of: March 31, 2016 December 31, 2015 Average Average Average Average Commercial paper 0.553 63 0.553 154 U.S. Government agencies 0.985 602 0.865 599 Corporate bonds and notes 1.727 328 1.757 331 The following table presents the fair value and unrealized losses related to our investments that have been in a continuous unrealized loss position for less than twelve months as of: March 31, 2016 December 31, 2015 Fair Value Unrealized Fair Value Unrealized (Thousands of dollars) Commercial paper $ 0 $ 0 $ 5,981 $ (5 ) U.S. Government agencies 11,996 (6 ) 8,969 (30 ) Corporate bonds and notes 134,298 (150 ) 232,347 (793 ) Total $ 146,294 $ (156 ) $ 247,297 $ (828 ) The following table presents the fair value and unrealized losses related to our investments that have been in a continuous unrealized loss position for more than twelve months as of: March 31, 2016 December 31, 2015 Fair Unrealized Fair Unrealized (Thousands of dollars) Corporate bonds and notes $ 47,783 $ (42 ) $ 28,866 $ (48 ) Total $ 47,783 $ (42 ) $ 28,866 $ (48 ) From time to time over the periods covered in our financial statements included herein (and as illustrated in the foregoing tables), our investments have experienced net unrealized losses. We consider these declines in market value to be due to market conditions, and we do not plan to sell these investments prior to maturity. For these reasons, we do not consider any of our investments to be other than temporarily impaired at March 31, 2016 or December 31, 2015. We have also determined that we did not have any other-than-temporary impairments relating to credit losses on debt securities for the three months ended March 31, 2016. For additional information regarding our criteria for making these assessments, see Note 2 to the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2015.

Revenue Recognition and Valuation Accounts	3. REVENUE RECOGNITION AND VALUATION ACCOUNTS We establish the amount of our allowance for doubtful accounts based upon factors relating to the credit risk of specific customers, current market conditions, and other information. Our allowance for doubtful accounts was approximately $5.4 million at March 31, 2016, and $5.2 million at December 31, 2015, respectively. Revenues related to flights generated by our Air Medical segment are recorded net of contractual allowances under agreements with third party payors and estimated uncompensated care when the services are provided. The allowance for contractual discounts was $129.8 million and $103.6 million as of March 31, 2016 and December 31, 2015, respectively. The allowance for uncompensated care was $30.7 million and $41.9 million as of March 31, 2016 and December 31, 2015, respectively. Included in the allowance for uncompensated care listed above is the value of services to patients who are unable to pay when it is determined that they qualify for charity care. The value of these services was $2.5 million and $2.7 million for the quarters ended March 31, 2016 and 2015, respectively. The estimated cost of providing charity services was $0.6 million for each of the quarters ended March 31, 2016 and 2015. The estimated costs of providing charity services are based on a calculation that applies a ratio of costs to the charges for uncompensated charity care. The ratio of costs to charges is based on our Air Medical segment’s total expenses divided by gross patient service revenue. The allowance for contractual discounts and estimated uncompensated care (expressed as a percentage of gross segment accounts receivable) was as follows: As of March 31, December 31, Allowance for Contractual Discounts 63 % 56 % Allowance for Uncompensated Care 15 % 23 % Under a three-year contract that commenced on September 29, 2012, our Air Medical affiliate provided multiple services to a customer in the Middle East, including helicopter leasing, emergency medical helicopter flight services, aircraft maintenance, provision of spare parts, insurance coverage for the customer-owned aircraft, training services, and base construction. The initial contract expired in late September 2015 and has been extended through late June 2016 on terms and conditions that have reduced the number of aircraft operated by us and the scope of our services and responsibilities. Each of the major services mentioned above qualify as separate units of accounting under the accounting guidance for such arrangements. The selling price for each specific service was determined based upon third-party evidence and estimates. We have also established valuation reserves related to obsolete and slow-moving spare parts inventory. The inventory valuation reserves were $16.8 million and $15.4 million at March 31, 2016 and December 31, 2015, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. FAIR VALUE MEASUREMENTS Accounting standards require that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. The following table summarizes the valuation of our investments and financial instruments by the above pricing levels as of the valuation dates listed: March 31, 2016 Total (Level 1) (Level 2) (Thousands of dollars) Investments: Money market mutual funds $ 17,877 $ 17,877 $ — Commercial paper 5,995 — 5,995 U.S. Government agencies 27,302 — 27,302 Corporate bonds and notes 250,301 — 250,301 301,475 17,877 283,598 Deferred compensation plan assets 2,334 2,334 — Total $ 303,809 $ 20,211 $ 283,598 December 31, 2015 Total (Level 1) (Level 2) Investments: Money Market Mutual Funds $ 18,181 $ 18,181 $ — Commercial Paper 5,981 — 5,981 U.S. Government Agencies 11,469 — 11,469 Corporate bonds and notes 264,228 — 264,228 299,859 18,181 281,678 Deferred compensation plan assets 2,294 2,294 — Total $ 302,153 $ 20,475 $ 281,678 We hold our short-term investments in an investment fund consisting of high quality money market instruments of governmental and private issuers, which is classified as a short-term investment. Level 1 inputs are quoted prices (unadjusted) for identical assets or liabilities in active markets. These items are traded with sufficient frequency and volume to provide pricing on an ongoing basis. The fair values of the shares of these funds are based on observable market prices, and therefore, have been categorized in Level 1 in the fair value hierarchy. Level 2 inputs reflect quoted prices for identical assets or liabilities that are not actively traded. These items may not be traded daily; examples include corporate bonds and U.S. government agencies debt. There have been no reclassifications of assets between Level 1 and Level 2 investments during the periods covered by the financial statements included in this report. We hold no Level 3 investments. Investments reflected on our balance sheets as Other assets, which relate to our liability under the Officers’ Deferred Compensation Plan, consist mainly of multiple investment funds that are highly liquid and diversified. Cash, accounts receivable, accounts payable and accrued liabilities, and our revolving credit facility debt all had fair values approximating their carrying amounts at March 31, 2016 and December 31, 2015. Our determination of the estimated fair value of our Senior Notes and our revolving credit facility debt is derived using Level 2 inputs, including quoted market indications of similar publicly-traded debt. The fair value of our Senior Notes, based on quoted market prices, was $457.5 million and $403.1 million at March 31, 2016 and December 31, 2015, respectively.

Interest is payable semi-annually on March 15 and September 15 of each year. PHI has the option to redeem some or all of the 2019 Notes at any time on or after March 15, 2016 at specified redemption prices. Prior to that time, PHI has the option to redeem some or all of the 2019 Notes pursuant to certain “make-whole” provisions or to redeem a portion of the 2019 Notes with the net proceeds of certain specified equity offerings. The indenture governing the 2019 Notes (the “2019 Indenture”) contains, among other things, certain restrictive covenants, including limitations on incurring indebtedness, creating liens, selling assets and entering into certain transactions with affiliates. The covenants also limit PHI’s ability to, among other things, pay cash dividends on common stock, repurchase or redeem common or preferred equity, prepay subordinated debt and make certain investments. Upon the occurrence of a “Change in Control Repurchase Event” (as defined in the 2019 Indenture), PHI will be required, unless it has previously elected to redeem the 2019 Notes as described above, to make an offer to purchase the 2019 Notes for a cash price equal to 101% of their principal amount. Revolving Credit Facility – Cash paid to fund interest expense was $13.7 million for the quarter ended March 31, 2016 and $13.5 million for the quarter ended March 31, 2015. Other –

As of March 31, 2016, we had options to purchase various aircraft that we currently operate under lease agreements with the aircraft owners. These options will become exercisable at various dates in 2016 through 2019. The aggregate option purchase prices are $67.8 million in 2016, $55.7 million in 2017, $127.0 million in 2018, $150.4 million in 2019 and $22.7 million in 2020. Whether we exercise these options will depend upon several factors, including market conditions and our available cash at the respective exercise dates. Environmental Matters – Legal Matters – Operating Leases At March 31, 2016, we had approximately $281.4 million in aggregate commitments under operating leases of which approximately $38.6 million is payable through December 31, 2016. The total lease commitments include $266.5 million for aircraft and $14.9 million for facility lease commitments.

Segment Reporting [Abstract]
Segment Information	10. SEGMENT INFORMATION PHI is primarily a provider of helicopter transport services, including helicopter maintenance and repair services. We report our financial results through the three reportable segments further described below. Each segment’s operating profit is its operating revenues less its direct expenses and selling, general and administrative expenses. Each segment has a portion of our total selling, general and administrative expenses that is charged directly to the segment and a small portion that is allocated to that segment. Allocated selling, general and administrative expenses are based primarily on total segment direct expenses as a percentage of total direct expenses. Unallocated overhead consists primarily of corporate selling, general and administrative expenses that we do not allocate to the reportable segments. In January 2016, we offered a Voluntary Employee Retirement Package (“VERP”) to all pilots who had attained age 64. Fifteen employees accepted this VERP, resulting in severance costs of $1.6 million recorded in the first quarter of 2016. At March 31, 2016, $0.8 million of severance costs from these offerings remained unpaid. During the quarter ended March 31, 2016, we also offered a voluntary furlough program to our Oil and Gas pilots whereby pilots who elect to participate in the program will receive severance pay and may continue medical coverage at their current employee-paid premiums. Twenty-six pilots accepted the offer with a total severance cost of $0.4 million. Under the terms of the furlough agreement, we must, no later than twelve months from the date of furlough offer each furloughed employee a right to return to work. Oil and Gas Segment. Operating revenue from our Oil and Gas segment is derived mainly from contracts that include a fixed monthly rate for a particular model of aircraft, plus a variable rate for flight time. A small portion of our Oil and Gas segment revenue is derived from providing services on an “ad hoc” basis. Operating costs for our Oil and Gas segment are primarily aircraft operations costs, including costs for pilots and maintenance personnel. Total fuel cost is included in direct expense and any reimbursement of a portion of these costs above a contracted per-gallon amount is included in revenue. For the quarters ended March 31, 2016 and 2015, approximately 54% and 59% of our total operating revenues were generated by our Oil and Gas segment. Air Medical Segment. As of March 31, 2016, 105 aircraft were assigned to our Air Medical segment. At such date, we operated approximately 100 aircraft domestically, providing air medical transportation services for hospitals and emergency service agencies in 19 states at 70 separate locations. We also provide air medical transportation services for a customer overseas. For our overseas program, we have deployed five aircraft at four locations, with four aircraft generating revenues as of March 31, 2016. Our Air Medical segment operates primarily under the independent provider model and, to a lesser extent, under the traditional provider model. Under the independent provider model, we have no fixed revenue stream and compete for transport referrals on a daily basis with other independent operators in the area. Under the traditional provider model, we contract directly with the customer to provide their transportation services, with the contracts typically awarded through competitive bidding. For the quarters ended March 31, 2016 and 2015, approximately 43% and 35% of our total operating revenues were generated by our Air Medical segment. As an independent provider, we bill for our services on the basis of a flat rate plus a variable charge per patient-loaded mile, regardless of aircraft model, and are typically compensated by private insurance, Medicaid or Medicare, or directly by transported patients who self-pay. As further described in Note 3, revenues are recorded net of contractual allowances under agreements with third party payors and estimated uncompensated care at the time the services are provided. Contractual allowances and uncompensated care are estimated based on historical collection experience by payor category (consisting mainly of insurance, Medicaid, Medicare, and self-pay). Estimates regarding the payor mix and changes in reimbursement rates are the factors most subject to sensitivity and variability in calculating our allowances. We compute a historical payment analysis of accounts fully closed, by category. Provisions for contractual discounts and estimated uncompensated care for our Air Medical segment (expressed as a percentage of gross segment billings) were as follows: Revenue Quarter 2016 2015 Gross Air Medical segment billings 100 % 100 % Provision for contractual discounts 71 % 74 % Provision for uncompensated care 3 % 0 % These percentages are affected by various factors, including rate increases and changes in the number of transports by payor mix. Net reimbursement per transport from commercial payors generally increases when a rate increase is implemented. Net reimbursement from certain commercial payors, as well as Medicare and Medicaid, generally does not increase proportionately with rate increases. Net revenue attributable to Insurance, Medicare, Medicaid, and Self-Pay (expressed as a percentage of net Air Medical revenues) were as follows: Quarter 2016 2015 Insurance 66 % 75 % Medicare 19 % 17 % Medicaid 15 % 8 % Self-Pay 0 % 0 % We also have a limited number of contracts with hospitals under which we receive a fixed monthly rate for aircraft availability and an hourly rate for flight time. Those contracts generated approximately 31% and 42% of the segment’s revenues for the quarters ended March 31, 2016 and 2015, respectively. Technical Services Segment. For the three month periods ended March 31, 2016 and 2015, approximately 3% and 6%, respectively, of our total operating revenues were generated by our Technical Services segment. Summarized financial information concerning our reportable operating segments for the quarters ended March 31, 2016 and 2015 is as follows: Quarter Ended March 31, 2016 2015 (Thousands of dollars) Segment operating revenues Oil and Gas $ 88,437 $ 120,396 Air Medical 70,060 72,385 Technical Services 5,519 11,416 Total operating revenues 164,016 204,197 Segment direct expenses (1) Oil and Gas (2) 91,916 100,331 Air Medical 57,044 60,039 Technical Services 3,594 8,905 Total segment direct expenses 152,554 169,275 Segment selling, general and administrative expenses Oil and Gas 1,528 1,159 Air Medical 2,595 2,629 Technical Services 224 114 Total selling, general and administrative expenses 4,347 3,902 Total direct and selling, general and administrative expenses 156,901 173,177 Net segment (loss) profit Oil and Gas (5,007 ) 18,906 Air Medical 10,421 9,717 Technical Services 1,701 2,397 Total net segment profit 7,115 31,020 Other, net (3) 256 469 Unallocated selling, general and administrative costs (1) (7,326 ) (7,335 ) Interest expense (7,533 ) (7,170 ) (Loss) earnings before income taxes $ (7,488 ) $ 16,984 (1) Included in segment direct expenses and unallocated selling, general, and administrative costs are the depreciation and amortization expense amounts below: Depreciation and Quarter Ended 2016 2015 Segment Direct Expense: Oil and Gas $ 9,918 $ 11,280 Air Medical 4,256 4,097 Technical Services 128 128 Total $ 14,302 $ 15,505 Unallocated SG&A $ 2,671 $ 2,646 (2) Includes Equity in loss of unconsolidated affiliate.

Investment in Variable Interest Entity	11. INVESTMENT IN VARIABLE INTEREST ENTITY We account for our investment in our West African operations as a variable interest entity, which is defined as an entity that either (a) has insufficient equity to permit the entity to finance its operations without additional subordinated financial support or (b) has equity investors who lack the characteristics of a controlling financial interest. As of March 31, 2016, we had a 49% investment in the common stock of PHI Century Limited (“PHIC”), a Ghanaian entity. We acquired our 49% interest on May 26, 2011, PHIC’s date of incorporation. The purpose of PHIC is to provide oil and gas flight services in Ghana and the West African region. For the quarters ended March 31, 2016 and 2015, we recorded a loss in equity of unconsolidated affiliate of $0 million and $0.1 million relative to our 49% equity ownership, respectively. We had $1.5 million of trade receivables as of March 31, 2016 from PHIC. At December 31, 2015, we recorded an allowance for bad debts against this trade receivable of $1.5 million, as we do not anticipate that we will be able to recover them. Our investment in the common stock of PHIC is included in Other assets on our Condensed Consolidated Balance Sheets and was $0 million at March 31, 2016 and December 31, 2015.

Condensed Consolidating Financial Information	13. CONDENSED CONSOLIDATING FINANCIAL INFORMATION As discussed further in Note 5, on March 17, 2014, PHI, Inc. issued $500 million of 5.25% Senior Notes due 2019 that are fully and unconditionally guaranteed on a joint and several, senior basis by all of our domestic subsidiaries. PHI, Inc. directly or indirectly owns 100% of all of its domestic subsidiaries. The supplemental condensed financial information on the following pages sets forth, on a consolidated basis, the balance sheet, statement of operations, statement of comprehensive income, and statement of cash flows information for PHI, Inc. (“Parent Company Only”) and the guarantor subsidiaries. The eliminating entries eliminate investments in subsidiaries, intercompany balances, and intercompany revenues and expenses. The condensed consolidating financial statements have been prepared on the same basis as the consolidated financial statements of PHI, Inc. The equity method is followed by the parent company within the financial information presented below. The transactions reflected in “Due to/from affiliates, net” in the following condensed consolidated statements of cash flows primarily consist of centralized cash management activities between PHI, Inc. and its subsidiaries, pursuant to which cash earned by the guarantor subsidiaries is regularly transferred to PHI, Inc. to be centrally managed. Because these balances are treated as short-term borrowings of the Parent Company, serve as a financing and cash management tool to meet our short-term operating needs, are large, turn over quickly and are payable to the guarantor subsidiaries on demand, we present borrowings and repayments with our affiliates on a net basis within the condensed consolidating statement of cash flows. Net receivables from our affiliates are considered advances and net payables to our affiliates are considered borrowings, and both changes are presented as financing activities in the following condensed consolidating statements of cash flows.
