Basis of Presentation [Abstract]
Basis of Presentation	1. Basis of Presentation  Travelport Worldwide Limited (the “Company” or “Travelport”) is a travel commerce platform providing distribution, technology, payment, mobile and other solutions for the global travel and tourism industry. With a presence in approximately 180 countries and territories, Travelport business is comprised of:  The Travel Commerce Platform, through which the Company facilitates travel commerce by connecting the world’s leading travel providers, such as airlines, hotel chains and car rental companies, with online and offline travel buyers in the Company’s proprietary business-to-business (“B2B”) travel platform. As customer needs and technologies evolve, Travelport continues to invest in its Travel Commerce Platform. Travelport has led innovation in electronic distribution and merchandising of airline core and ancillary products and extensively divested its offerings to hotel, car rental, rail, cruise-line and tour operators. In addition, Travelport has leveraged its domain expertise in the travel industry to design a pioneering B2B payment solution that addresses the need of travel agencies to efficiently and securely make payments to travel providers globally. The Company also has a strong focus on mobile commerce, providing a wide range of services that allows airlines, hotels, corporate travel management companies and travel agencies to engage with their customers through digital services, including apps, corporate booking tools and mobile messaging. Travelport utilizes the extensive data managed by its platform to provide an array of additional services, such as advertising solutions, subscription services, business intelligence data services, and marketing-oriented analytical tools to travel agencies, travel providers and other travel data users. Through its Technology Services, Travelport provides critical hosting services to airlines, such as shopping, ticketing, departure control, business intelligence and other solutions, enabling them to focus on their core business competencies and reduce costs. The Company hosts reservations, inventory management and other related critical systems for Delta Air Lines Inc.  The Company has two operating segments, Travelport and eNett; however, the Company reports them together as one reportable segment as eNett does not meet the criteria for a separate reportable segment.  These consolidated condensed financial statements and other consolidated condensed financial information included in this Quarterly Report on Form 10-Q are unaudited, with the exception of the December 31, 2017 consolidated condensed balance sheet, which was derived from audited consolidated financial statements. These consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting. Certain disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations.  In presenting the consolidated condensed financial statements in accordance with U.S. GAAP, management makes estimates and assumptions that affect the amounts reported and related disclosures. Estimates, by their nature, are based on judgments and available information. Accordingly, actual results could differ from those estimates. In management’s opinion, the consolidated condensed financial statements contain all normal recurring adjustments necessary for a fair presentation of interim results reported. The results of operations reported for interim periods are not necessarily indicative of the results of operations for the entire year or any subsequent interim period. These consolidated condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on February 20, 2018.  The Company has reclassified prior period information as a result of the Company's adoption of new guidance on pensions as further described in Note 2–Recently Issued Accounting Pronouncements.

Basis of Presentation [Abstract]
Recently Issued Accounting Pronouncements	2. Recently Issued Accounting Pronouncements  Accounting Pronouncements Adopted  Equity-Based Compensation—Modification Accounting  In May 2017, the Financial Accounting Standards Board (the “FASB”) issued guidance clarifying when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This guidance does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and will not be required if the changes are considered non-substantive. The Company adopted the provisions of this guidance prospectively effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Pension  In March 2017, the FASB issued guidance on the presentation of net periodic pension cost and post-retirement benefit cost (“net benefit cost”). The new guidance requires the service cost component of net benefit cost to be presented as part of the other employee compensation costs in operating income, which can be further considered for capitalization as part of the capitalization policy, and to present the other components of net benefit cost, including interest costs, expected return on plan assets and amortization of actuarial gain or loss (the “other components”) separately, in one or more line items, outside of operating income. Further, the new guidance requires a disclosure of the line items that contain the other components of net benefit cost in the footnotes to the financial statements if they are not presented on appropriately described separate lines in the statement of operations. The Company adopted the provisions of this guidance effective January 1, 2018, as required under the guidance, and for the three and six months ended June 30, 2017 , the Company reclassified $1 million and $2 million, respectively, related to the other components from selling, general and administrative expense to other expense within the consolidated condensed statements of operations. The adoption of this guidance did not have an impact on the Company’s net income, consolidated condensed balance sheets or statements of cash flows.  Goodwill Impairment  In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. The guidance removes step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under this guidance a goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value. The new guidance is applicable for interim and annual reporting periods beginning after December 15, 2019. Early adoption of the amendments in the guidance is permitted for any impairment tests performed after January 1, 2017 and requires its application using a prospective transition method. The Company early adopted the provisions of this guidance effective January 1, 2018. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Restricted Cash  In November 2016, the FASB issued guidance that requires entities to include restricted cash as part of cash and cash equivalents in the statement of cash flows. The guidance also requires a reconciliation of cash, cash equivalents and restricted cash balances disclosed in the balance sheet with the corresponding amounts as shown in the statement of cash flows. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Statement of Cash Flows  In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments provide specific guidance relating to the classification of certain items, including cash payments for debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, distributions received from equity method investments and cash flows classification based on its predominate source or use. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.     Financial Instruments  In January 2016, the FASB issued guidance that amends the current guidance on the classification and measurement of financial instr uments. The guidance significantly revises the accounting related to (i) the classification and measurement of investments in equity securities of unconsolidated subsidiaries (other than those accounted for using the equity method of accounting) and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. The guidance also amends certain disclosure requirements associated with the fair value of financial instruments. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Revenue Recognition  In May 2014, the FASB issued guidance on revenue from contracts with customers that superseded most current revenue recognition guidance, including industry-specific guidance. The underlying principle of the guidance is to recognize revenue to depict the transfer of goods or services to customers at an amount to which the company expects to be entitled in exchange for those goods or services. The new guidance requires an evaluation of revenue arrangements with customers following a five-step approach: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the company satisfies each performance obligation. Revenue is recognized when cont rol of the promised services is transferred to the customers in an amount that reflects the expected consideration in exchange for those services. A customer obtains control when it has the ability to direct the use of and obtain the benefits from the services. Other major provisions of the guidance include capitalization of certain contract costs, consideration of the time value of money in the transaction price and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have a material impact on the Company’s consolidated condensed financial statements (see Note 3 – Revenue).  Accounting Pronouncements Not Yet Adopted  Financial Instruments—Credit Losses  In June 2016, the FASB issued guidance that amends the accounting for credit losses on financial instruments. The guidance adds an impairment model that is based on expected losses rather than incurred losses. Under this new guidance, allowance for credit losses will be recognized based on the estimate of expected credit losses, which will result in more timely recognition of such losses. The guidance requires all available relevant information to be considered when estimating expected credit losses, including details about past events, current conditions and reasonable and supportable forecasts and their implications for expected credit losses. The new guidance is applicable to the Company for interim and annual reporting periods beginning after December 15, 2019 and requires its application using a retrospective transition method. The Company is currently evaluating the impact of the amended guidance on its consolidated condensed financial statements.  Leases  In February 2016, the FASB issued guidance on lease accounting that supersedes the current guidance on leases. The new guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. The guidance requires adoption using a modified retrospective approach at the beginning of the earliest comparative period presented in the financial statements.  In July 2018, the FASB issued further guidance to provide another option for transition under which, the comparative periods presented in the financial statements in the year of adoption will not need to be restated. Under this transition method, the entity can apply the transition provisions on January 1, 2019 (i.e. the effective date). The Company expects to adopt the new lease guidance by applying the transition provisions on January 1, 2019.  The Company is currently evaluating the impact of the guidance on its consolidated condensed financial statements and related disclosures, controls and processes including evaluating the use of optional practical expedients. Further, the Company has selected a lease accounting system to assist with the accounting and disclosure requirements under the new guidance and is currently analyzing its inventory of existing operating leases. The Company expects a majority of its existing operating leases, with minimum lease commitments as of June 30, 2018 of $98 million, will be subject to the new guidance. Upon adoption of the guidance, the Company will recognize operating lease ROU assets and operating lease liabilities on its consolidated condensed balance sheets that will increase its total assets and liabilities. Although, the new guidance is not expected to materially impact the Company’s consolidated condensed statements of operations or its consolidated condensed statements of cash flows, the guidance requires enhanced disclosures related to the nature, amount, timing and uncertainty of cash flows arising from operating and finance leases contracts.

Revenues [Abstract]
Revenue	3. Revenue  On January 1, 2018, the Company adopted the new revenue recognition guidance applying the modified retrospective method to all contracts. Results for reporting periods beginning after January 1, 2018 are presented under the new revenue recognition guidance, while prior period amounts are not adjusted and continue to be reported in accordance with the historic accounting under previous revenue recognition guidance. The Company recorded a $1 million reduction to its accumulated deficit balance as of January 1, 2018, representing the cumulative impact of adopting the new revenue recognition guidance, which primarily relates to the timing of recognition of hotel reservations in the Company’s Beyond Air revenue. For the three and six months ended June 30, 2018, there was an immaterial impact to net revenue as a result of applying the new revenue recognition guidance. The Company operates a travel commerce platform providing distribution, technology, payment, mobile and other solutions for the global travel and tourism industry. Through its Travel Commerce Platform, the Company connects travel providers (“customers”), such as airlines, hotel chains and car rental companies , with online and offline travel buyers, including travel agencies, travel management companies and corporations. The Company also provides critical information technology services to airlines, such as shopping, ticketing, departure control, business intelligence and other solutions.  The following table presents the Company’s net revenue disaggregated by its source. Sales and usage-based taxes are excluded from net revenue.   Three Months Ended Six Months Ended  June 30, June 30,  (in $ thousands) 2018 2018  Air $ 443,947 $ 916,882  Beyond Air 194,021 373,772  Travel Commerce Platform (1) 637,968 1,290,654  Technology Services 24,040 49,192  Net revenue $ 662,008 $ 1,339,846 (1) Includes $13 million and $31 million of Travel Commerce Platform revenue for the three and six months ended June 30, 2018, respectively, that does not represent revenue recognized from contracts with customers.  Travel Commerce Platform Revenue  Travel Commerce Platform revenue primarily utilizes a transaction volume model to recognize revenue. The Company charges a fee per segment booked. The Company also receives a fee for cancellations of bookings previously made on the Company’s platform and a fee for tickets issued by the Company that were originally booked on an alternative system.  Revenue for air bookings is recognized at the time of reservation, net of estimated cancellations and anticipated incentives payable to customers. Cancellations prior to the date of departure are estimated based on the historical level of cancellations (net of cancellation fees).  The Company’s Beyond Air portfolio includes hospitality, payment solutions, digital services, advertising and other platform services. Revenue for hotel reservations is recognized upon check-in , and revenue for car reservations is recognized upon pick-up, as such reservations can generally be cancelled without penalty. The Company’s payment solutions revenue is earned primarily as a percentage of total transaction value in the form of a share of interchange fees. Revenue is recognized at the point in time when the payment is processed.  The Company collects annual fees from travel agencies, internet sites and other subscribers to access the applications on its Travel Commerce Platform, including providing the ability to access schedule and fare information, book reservations and issue tickets. Where the contractual terms are on a subscription basis with fixed amounts of fees, revenue is recognized ratably over the contract period as the performance obligation is satisfied over time. Where the contractual terms are transaction-based with fees charged per transaction, revenue is recognized as the services are provided. The table below sets forth Travel Commerce Platform revenue disaggregated by region:     Three Months Ended Six Months Ended  June 30, June 30,  (in $ thousands) 2018 2018  Asia Pacific $ 144,991 $ 286,542  Europe 223,340 467,782  Latin America and Canada 29,456 59,315  Middle East and Africa 81,663 160,769  International 479,450 974,408  United States 158,518 316,246  Travel Commerce Platform (1) $ 637,968 $ 1,290,654 (1) Includes $13 million and $31 million of Travel Commerce Platform revenue for the three and six months ended June 30, 2018, respectively, that does not represent revenue recognized from contracts with customers.  Technology Services Revenue  The Company collects fees, generally on a monthly basis under long-term contracts, for providing hosting solutions and other services to airlines , such as shopping, ticketing, departure control, business intelligence and other solutions. Where the contractual terms are on a subscription basis with fixed amounts of fees, revenue is recognized ratably over the contract period as the performance obligation is satisfied over time. Where the contractual terms are transaction-based with fees charged per transaction, revenue is recognized as the services are provided.  Contract Balances  Contract assets represent the Company’s right to consideration in exchange for services transferred to a customer when that right is conditioned on the Company’s future performance obligations. Contract liabilities represent the Company’s obligation to transfer services to a customer for which the entity has received consideration (or the amount is due) from the customer.  As of June 30, 2018, the Company did not have contract assets. The opening and closing balances of the Company’s accounts receivables and contract liabilities (current and non-current) are as follows:     Contract Liabilities  (in $ thousands) Accounts Receivable, net (1) Deferred Revenue (current) (1) Deferred Revenue (non-current) (1)  Balance as of June 30, 2018 $ 219,735 $ 32,398 $ 5,678  Balance as of January 1, 2018 174,765 32,010 6,056  Increase $ 44,970 $ 388 $ (378) (1) Accounts receivables, net, and deferred revenue exclude balances not related to contracts with customers.  The majority of the Company’s Air revenue within its Travel Commerce Platform is collected through the Airline Clearing House (“ACH”) and other similar clearing houses, whereby the payments are submitted monthly to the ACH and are settled (on a net basis) within approximately 30 days. Airlines that do not settle payment s through the ACH and customers in Beyond Air and Technology Services are generally invoiced on a monthly basis, and the payments are generally received within approximately 30 - 60 days.  Deferred revenue is recorded when a performance obligation has not been satisfied but an invoice has been raised . The cash payments received or due in advance of the satisfaction of the Co mpany’s performance obligations was offset by $12 million of net revenue recognized that was included in the deferred revenue balance as of January 1, 2018 .    Remaining Performance Obligations  As of June 30, 2018, the aggregate amount of the transaction price allocated to the Company’s remaining performance obligations was approximately $63 million, of which the Company expects to recognize revenue of approximately 79% over the next 24 months, including approximately 50% over the next 12 months.  The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected term of one year or less and (ii) contracts for which the Company recognizes revenue at the amounts to which it has the right to invoice for services performed.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	4. Income Taxes  The Company’s tax provision differs significantly from the expected provision amount calculated at the U.S. federal statutory rate primarily as a result of (i) being subject to income tax in numerous non-U.S. jurisdictions with varying income tax rates, (ii) a valuation allowance maintained in various jurisdictions, including the U.S. and the U.K., due to historical losses in such jurisdictions, (iii) certain expenses that are not deductible for tax or do not secure an effective tax deduction under the relevant jurisdictions, (iv) certain income or gains that are not subject to tax, (v) items identified as discrete during the interim period, (vi) the impact of the U.S. Tax Reforms (as defined below) and (vi i ) the impact of changes in the U.K. to the tax deductibility of interest.  As of December 31, 2017, the Company had U.S. federal net operating losses (“NOL”) carry forwards of approximately $400 million, which expire between 2032 and 2037, state NOL carry forwards, which expire between 2018 and 2037, and alternative minimum tax (“AMT”) and other tax credits carry forward of approximately $27 million. The Company had other non–U.S. NOL carry forwards of $345 million that expire between three years and indefinitely. As of December 31, 2017, t he deferred tax asset in respect of these U.S. and non–U.S. NOL carry fo rwards and U.S. tax credits was $197 million. The Company believes it is more likely than not that the benefit from certain U.S. federal, U.S. state and non–U.S. NOL carry forwards and other deferred tax assets will not be realized. Consequently, the Company has recorded valuation allowances of $187 million a gainst such deferred tax assets as of December 31, 2017.  The Company regularly assesses its ability to realize deferred tax assets. As of June 30, 2018, the Company’s estimated annual effective tax rate includes the impact of (i) releasing a portion of the valuation allowance associated with the U.S. NOL carry forwards due to an increase in taxable temporary differences that support deferred tax asset utilization and (ii) releasing a portion of the valuation allowance associated with the U.K. NOL carry forwards (see below). However, the Company has maintained a valuation allowance on the remaining deferred tax assets. Future realized earnings performance and changes in future earnings projections, among other factors, may cause an adjustment to the conclusion as to whether it is more likely than not that the Company will realize the benefit of the deferre d tax assets . This would impact the income tax expense in the period for which it is determined that these factors have changed.  As a result of the Company’s debt restructuring in March 2018 (see Note 11–Long-Term Debt), the Company expects that there will be future taxable income in the U.K. other than the reversal of deferred tax liabilities. Consequently, the Company has realized a benefit of $10 million in the first quarter of 2018 following the release of the valuation allowance on deferred tax assets associated with U.K. NOL carry forwards.  The Company’s preliminary estimate of the impact of the comprehensive changes to the U.S. tax legislation that were enacted in December 2017 under the Tax Cuts and Jobs Act (the “U.S. Tax Reforms”) is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the U.S. Tax Reforms, the impact of state income taxes, administrative interpretations or court decisions interpreting the U.S. Tax Reforms that may require further adjustments and changes in the Company’s estimates that could be beneficial or adverse. The Company continued to assess the impact of the U.S. Tax Reforms during the six months ended June 30, 2018 and expects to complete its assessment and resultant accounting, if any, by December 2018 (being the one–year measurement period from the date of enactment of the U.S. Tax Reforms).

(2) As of December 31, 2017, the principal amount of term loans outstanding under the 2014 Credit Agreement (as defined below) was $2,154 million, which is netted for unamortized debt discount of $17 million and unamortized debt finance costs of $13 million. (3) As of June 30, 2018, the principal amount of senior secured notes outstanding was $745 million, which is netted for unamortized debt finance costs of $7 million.  Senior Secured Credit Agreement  In March 2018, Travelport Finance (Luxembourg) S.à r.l. (the “Borrower”), a wholly-owned subsidiary of the Company, entered into a new senior secured credit agreement (the “2018 Credit Agreement”). Under the 2018 Credit Agreement, the lenders agreed to extend credit to the Borrower in the form of (a) initial secured term loans in an aggregate principal amount of $1,400 million maturing in March 2025, issued at a discount of 0.50% , which amortizes in quarterly installments, commencing August 31, 2018, equal to 0.25% of the original principal amount of the term loans, with the balance payable at maturity and (b) a revolving credit facility in an aggregate principal amount of $150 million maturing in September 2022. The Company used the proceeds from these term loans , together with the proceeds from the issuance of senior secured notes (discussed below) and cash on the balance sheet, to repay the outstanding balance remaining of the term loans under the previous senior secured credit agreement (the “2014 Credit Agreement”) and to pay the related transaction expenses and fees. Upon the repayment in full of the obligations, the 2014 Credit Agreement was terminated. The Company recorded the debt refinancing transaction as the issuance of new debt and extinguishment of prior debt and recognized a loss on early extinguishment of debt of $28 million in its consolidated condensed statements of operations for the six months ended June 30, 2018.  Under the 2018 Credit Agreement, the interest rate per annum applicable to (a) the term loans is based on, at the election of the Borrower, LIBOR plus 2.50% or base rate (as defined in the 2018 Credit A greement) plus 1.50% and (b) the borrowings under revolving credit facility, at the election of the Borrower, LIBOR plus 2.25% or base rate (as defined in the agreement) plus 1.25% . LIBOR rates and base rates have a floor of 0.00% . The Company expects to pay interest based on LIBOR.  Further, during the six months ended June 30, 2018, the Company (i) repaid a quarterly installment of $6 million principal amount of term loans outstanding under the 2014 Credit Agreement, (ii) amortized $ 2 million of debt finance costs and $1 million of debt discount, (iii) repaid $ 18 million under its capital lease obligations and entered into new capital leases arrangements for information technology assets resulting in a $62 million increase in capital lease obligations and (iv) repaid $ 1 million under its other indebtedness obligations.  As discussed above, in March 2018, the Borrower entered into a new revolving credit facility under the 2018 Credit Agreement with a consortium of banks. The lenders, terms, credit facility amount and maturity date under the new revolving credit facility are substantially the same as under the 2014 Credit Agreement, except for the reduction in interest rates discussed above. Under the new terms, the Borrower has a $150 million revolving credit facility, which contains a letter of credit sub-limit up to a maximum of  $100 million. As of June 30, 2018, there were no outstanding borrowings under the revolving credit facility under the 2018 Credit Agreement, and $ 8 million was utilized for the issuance of letters of credit, with a balance of $ 142 million remaining.  Senior Secured Notes  In March 2018, Travelport Corporate Finance PLC (the “Issuer”), a wholly-owned subsidiary of the Company, issued a principal amount of $745 million in senior secured notes due in March 2026 with a stated interest rate of 6.00% per annum. The proceeds were used to repay a portion of the term loans outstanding under the 2014 Credit Agreement. The interest on the senior secured notes is payable semi-annually in cash in arrears on March 15 and September 15 of each year, commencing September 15, 2018.

The debt finance costs are amortized over the term of the related debt as part of interest expense in the consolidated condensed statements of operations. The movements in total unamortized debt finance costs for the six months ended June 30, 2018 and 2017 are summarized below:    Six Months Six Months  Ended June 30, Ended June 30,  (in $ thousands) 2018 2017  Balance as of January 1 $ 14,708 $ 22,855  Capitalization of debt finance costs 14,799 —  Amortization (1,518) (2,847)  Write-off on early extinguishment of debt (12,059) —  Balance as of June 30 $ 15,930 $ 20,008       Debt Covenants and Guarantees  The 2018 Credit Agreement and the Indenture governing the senior secured notes contain financial and other covenants, including: limitations on the ability of Travelport Limited, a wholly-owned subsidiary of the Company and the Borrower’s and the Issuer’s immediate parent entity (the “Parent Guarantor”) and its restricted subsidiaries to incur debt or liens or make certain investments and acquisitions and restricted payments, limitations on transactions with affiliates and certain restrictions on the sale of assets. A violation of these covenants could result in the Parent Guarantor and its restricted subsidiaries being prohibited from making certain restricted payments, including dividends, or cause a default under the 2018 Credit Agreement or the Indenture, which would permit the participating lenders to restrict the Parent Guarantor’s and its restricted subsidiaries’ ability to access the revolving credit facility and require the immediate repayment of any outstanding advances made under the 2018 Credit Agreement or the Indenture. Solely in the case of the revolving credit facility under the 2018 Credit Agreement, if the amount outstanding under the revolving credit facility exceeds a certain threshold, there is a requirement to maintain a first lien leverage ratio.  The senior secured notes are guaranteed fully and unconditionally on a senior secured basis by the Parent Guarantor and certain of its existing and future wholly-owned subsidiaries that also guarantee the facilities under the 2018 Credit Agreement. The senior secured notes and related guarantees are secured on a first-priority basis by security interests in all of the Issuer’s and the guarantors’ assets that also secure the facilities under the 2018 Credit Agreement on a first-priority basis. As of June 30, 2018, the Company was in full compliance with all restrictive and financial covenants related to its debt.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	12. Financial Instruments  The Company uses derivative financial instruments as part of its overall strategy to manage its exposure to market risks primarily associated with fluctuations in foreign currency exchange rates and interest rates. The Company does not use derivatives for trading or speculative purposes. During the six months ended June 30, 2018 , there were no material change s in the Company’s foreign currency and interest rate risk management policies or in its fair value methodology. As of June 30, 2018, the Company had a net asset position o f  $ 10 million related to its derivative financial instruments.  Foreign Currency Risk  The Company’s primary foreign currency risk exposure as of June 30, 2018 was due to exchange rate fluctuations that arise from certain intercompany transactions and earnings denominated in non-U.S. dollar currencies and from non-functional currency denominated assets and liabilities.  The Company uses foreign currency derivative contracts (forward contracts) to manage its exposure to changes in foreign currency exchange rates, primarily exposure to British pound, Euro and Australian dollar. The Company did not designate these foreign currency derivative contracts as accounting hedges. Fluctuations in the value of these foreign currency derivative contracts were recorded within the Company’s consolidated condensed statements of operations, which partially offset the impact of the changes in the value of the foreign currency denominated receivables and payables and forecasted earnings they were intended to economically hedge.  Interest Rate Risk  As of June 30, 2018, the Company’s primary interest rate risk exposure was to interest rate fluctuations in the United States, specifically the impact of LIBOR interest rates on the Company’s U.S. dollar denominated variable rate term loans. During the six months ended June 30, 2018, the average LIBOR rate applied to the term loans was 1.88% . In order to protect against potential higher interest costs resulting from increases in LIBOR, as of June 30, 2018, the Company had outstanding interest rate swap contracts that fix the LIBOR rate payable as follows:     Average  Notional Amount Interest  ($ in thousands) Period Rate  1,400,000 February 2017 to February 2019 1.4010%  1,200,000 February 2019 to February 2020 2.1906%  400,000 February 2020 to February 2021 2.1925%  100,000 February 2021 to February 2022 3.0655%    As of June 30, 2018, the net notional amounts of the Company’s derivative contracts are as follows:    June 30, December 31,  (in $ thousands) 2018 2017  Interest rate swap contracts $ 3,100,000 $ 3,000,000  Foreign currency contracts 439,926 373,487  As of June 30, 2018, the interest rate swap contracts cover varying periods as disclosed above and the foreign currency contracts cover the twelve month period until June 2019.  Presented below is a summary of the gross fair value of the Company’s derivative contracts, which have not been designated as hedging instruments, recorded on the consolidated condensed balance sheets:     Fair Value Asset Fair Value (Liability)  Balance Sheet June 30, December 31, Balance Sheet June 30, December 31,  (in $ thousands) Location 2018 2017 Location 2018 2017  Interest rate swap contracts Other current assets $ 12,830 $ 4,799 Accrued expenses and other current liabilities $ — $ —  Interest rate swap contracts Other non-current assets 8,369 3,503 Other non-current liabilities (122) (51)  Foreign currency contracts Other current assets 757 10,434 Accrued expenses and other current liabilities (11,453) (292)  Total fair value of derivative assets (liabilities) $ 21,956 $ 18,736 $ (11,575) $ (343)  The following table provides a reconciliation of the movement in the net carrying amount of derivative financial instruments during the six months ended June 30, 2018 and 2017:   Six Months Ended Six Months Ended  (in $ thousands) June 30, 2018 June 30, 2017  Net derivative asset (liability) opening balance $ 18,393 $ (19,196)  Total gain for the period included in net income 3,098 6,529  (Proceeds from) payments on settlement of derivative contracts (11,110) 10,851  Net derivative asset (liability) closing balance $ 10,381 $ (1,816)  The table below presents the impact of the changes in fair values of derivatives not designated as hedges on net income during the three and six months ended June 30, 2018 and 2017:     Amount of Gain (Loss)  Recorded in Net Income  Three Months Ended Six Months Ended  June 30, June 30,  (in $ thousands) Statement of Operations Location 2018 2017 2018 2017  Interest rate swap contracts Interest expense, net $ 4,866 $ (4,880) 16,088 (4,654)  Foreign currency contracts Selling, general and administrative (18,049) 9,125 (12,990) 11,183  $ (13,183) $ 4,245 3,098 6,529       Fair Value Disclosures for All Financial Instruments  The carrying amounts of cash and cash equivalents, accounts receivable, other current assets, accounts payable and accrued expenses and other current liabilities approximate fair value due to the short-term maturities of these assets and liabilities.  The fair values of the Company’s other financial instruments are as follows:     June 30, 2018 December 31, 2017  (in $ thousands) Fair Value Hierarchy Carrying Amount Fair Value Carrying Amount Fair Value  Asset (liability)  Derivative assets Level 2 $ 21,956 $ 21,956 $ 18,736 $ 18,736  Derivative liabilities Level 2 (11,575) (11,575) (343) (343)  Total debt Level 2 (2,272,858) (2,293,401) (2,230,013) (2,258,893)  The significant unobservable inputs used to fair value the Company’s derivative financial instruments are based on market quoted probability rates of default for each of the derivative assets and liabilities, resulting in a weighted average probability of default of 2% and a recovery rate of 75% for derivative assets and 65% for derivative liabilities. As the credit valuation adjustment applied to arrive at the fair value of derivatives is less than 15% of the unadjusted fair value of derivative instruments for two consecutive quarters, the Company has categorized derivative fair valuations at Level 2 of the fair value hierarchy. A 10% change in the significant unobservable inputs will not have a material impact on the fair value of the derivative financial instruments as of June 30, 2018.  The fair value of the Company’s total debt has been determined by calculating the fair value of its term loans and senior secured notes based on quoted prices obtained from independent brokers for identical debt instruments when traded as an asset and is categorized within Level 2 of the fair value hierarchy.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. Commitments and Contingencies  Purchase Commitments  In the ordinary course of business, the Company makes various commitments to purchase goods and services from specific suppliers, including those related to capital expenditures. As of June 30, 2018, the Company had approximately $98 million of outstanding purchase commitments, primarily relating to service contracts for information technology, of which $49 million relates to the twelve months ending June 30, 2019. These purchase obligations extend through 2022.  Contingencies  Company Litigation  The Company is involved in various claims, legal proceedings and governmental inquiries related to contract disputes, business practices, intellectual property and other commercial, employment and tax matters. The Company believes it has adequately accrued for such matters as appropriate or, for matters not requiring accrual, believes they will not have a material adverse effect on its results of operations, financial position or cash flows based on information currently available. However, litigation is inherently unpredictable and although the Company believes its accruals are adequate and/or that it has valid defenses in these matters, unfavorable resolutions could occur, which could have a material effect on the Company’s results of operations or cash flows in a particular reporting period.  Standard Guarantees/Indemnification  In the ordinary course of business, the Company enters into numerous agreements that contain standard guarantees and indemnities whereby the Company indemnifies another party for breaches of representations and warranties. In addition, many of these parties are also indemnified against any third-party claim resulting from the transaction that is contemplated in the underlying agreement. Such guarantees or indemnifications are granted under various agreements, including those governing (i) purchases, sales or outsourcing of assets or businesses, (ii) leases of real estate, (iii) licensing of trademarks, (iv) use of derivatives and (v) issuances of debt or equity securities. The guarantees or indemnifications issued are for the benefit of the (i) buyers in sale agreements and sellers in purchase agreements, (ii) landlords in lease contracts, (iii) licensees of the Company’s trademarks, (iv) financial institutions in derivative contracts and (v) underwriters in debt or equity security issuances. While some of these guarantees extend only for the duration of the underlying agreement, many survive the expiration of the term of the agreement or extend into perpetuity (unless subject to a legal statute of limitations). There are no specific limitations on the maximum potential amount of future payments the Company could be required to make under these guarantees, nor is the Company able to develop an estimate of the maximum potential amount of future payments to be made under these guarantees, as the triggering events are not subject to predictability and there is little or no history of claims against the Company under such arrangements. With respect to certain of the aforementioned guarantees, such as indemnifications of landlords against third-party claims for the use of real estate property leased by the Company, the Company maintains insurance coverage that mitigates any potential payments to be made.

Equity	14. Equity  Sale of Shares of a Subsidiary  In April 2017, the Company sold its 51% controlling interest in IGT Solutions Private Ltd. (“IGTS”) for a total gross cash consideration of $18 million and recorded a gain on sale of such subsidiary of $1 million, which includes the reclassification of loss on currency translation adjustment from accumulated other comprehensive loss of  $4 million. The Company no longer owns any shares in, and/or controls, IGTS following the sale.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity-Based Compensation	15. Equity-Based Compensation  Restricted Share Units (“RSUs”)  During the first quarter of 2018, as part of its annual grant program, the Company granted 596,063 RSUs. These RSUs vest one-fourth annually over a period of four years, if the employee continues to remain in employment during the vesting period. The Company further granted 202,100 RSUs to certain employees that cliff-vest in approximately two years from the grant date upon continued employment of the employee during the vesting period. RSUs accrue dividend equivalents associated with the underlying common shares as dividends are declared by the Company. Dividends will generally be paid to holders of RSUs in cash upon the vesting of the associated RSUs and will be forfeited should the RSUs not vest. The RSUs do not have an exercise price, and the fair value of the RSUs is considered to be the closing market price of the Company’s common shares at the date of grant. Certain of the Company’s outstanding RSUs may be settled by the issuance of common shares held as treasury shares. In line with the Company’s accounting policy, the compensation costs related to RSUs are expensed on a straight-line ba sis.   The table below presents the activity of the Company’s RSUs for the six months ended June 30, 2018:    Weighted Average  Grant Date  (in dollars, except number of RSUs) Number Fair Value  Balance as of January 1, 2018 1,526,280 $ 13.01  Granted at fair market value 857,133 $ 14.62  Vested (1) (427,673) $ 12.94  Forfeited (168,966) $ 13.06  Balance as of June 30, 2018 1,786,774 $ 13.79 _____________________  (1) During the six months ended June 30, 2018, the Company completed net share settlements of 150,911 common shares in connection with employee taxable income created upon vesting of RSUs. The Company agreed to pay these taxes on behalf of the employees in return for the employees returning an equivalent value of common shares. These common shares were accounted for as treasury shares by the Company. Further, in respect of 51,396 vested RSUs, certain directors of the Company elected to defer receiving common shares until termination of their service as a director of the Company.  Performance Share Units (“PSUs”)  During the first quarter of 2018, as part of its annual grant program, the Company granted 1,246,803 PSUs. The PSUs cliff-vest at the end of approximately three years from the date of the grant based on the satisfaction of certain performance conditions and continued employment of the employee during the vesting period. The ultimate number of PSUs that will vest also depends on the Company’s ranking within a group of companies based on achievement of its total shareholder’s return (“TSR”) during the applicable performance period compared to the TSR of the companies within the selected group. However, the total number of PSUs that will ultimately vest will not exceed 200% of the original grant. Each reporting period, the Company assesses the probability of vesting, and, if there is any change in such probability, the Company records the cumulative effect of the adjustment in the current repor ting period. All of the PSUs will be settled in the Company’s common shares. PSUs accrue dividend equivalents associated with the underlying common shares as dividends are declared by the Company. Dividends will generally be paid to holders of PSUs in cash upon the vesting of the associated PSUs and will be forfeited should the PSUs not vest. The PSUs do not have an exercise price. For PSUs earned based on a market condition, the Company utilizes a Monte Carlo simulation to determine the fair value of these awards at the date of grant. Certain of the Company’s outstanding PSUs may be settled by the issuance of common shares held as treasury shares. In line with the Company’s accounting policy, the compensation costs related to the PSUs are expensed on a straight-line basis.  The table below presents the activity of the Company’s PSUs for the six months ended June 30, 2018:    Weighted Average  Grant Date  (in dollars, except number of PSUs) Number Fair Value  Balance as of January 1, 2018 2,694,999 $ 13.10  Granted at fair market value 1,444,522 $ 16.33  Forfeited (441,794) $ 12.93  Vested (1) (11,290) $ 15.50  Balance as of June 30, 2018 (2) 3,686,437 $ 14.33 _____________________  (1) During the six months ended June 30, 2018, the Company completed net share settlements of 3,321 common shares in connection with employee taxable income created upon vesting of PSUs. The Company agreed to pay these taxes on behalf of the employees in return for the employees returning an equivalent value of common shares. These common shares were accounted for as treasury shares by the Company.  (2) Total estimated awards that ultimately will vest based on the Company’s forecasted performance against the pre-defined targets and before considering any adjustments that may be necessary based on the ranking of the Company’s TSR compared to the TSR of the selected group is expected to be 4,074,664 PSUs.                Stock Options  During the six months ended June 30, 2018, the Company did not grant any stock options.  The table below presents the activity of the Company’s stock options for the six months ended June 30, 2018:    Weighted Average  Weighted Average Remaining Aggregate  Exercise Price Contractual Terms Intrinsic Value  Number of Options (in dollars) (in years) (in $ thousands)  Balance as of January 1, 2018 2,352,928 $ 13.51  Forfeited (157,403) $ 13.67  Exercised (461,805) $ 10.98  Expired (43,914) $ 15.56  Balance as of June 30, 2018 1,689,806 $ 14.13 7.24 $ 7,449  Exercisable as of June 30, 2018 909,890 $ 14.44 7.03 $ 3,730  Expected to vest as of June 30, 2018 779,916 $ 13.77 7.48 $ 3,719  Total equity-based compensation expense recognized in the Company’s consolidated condensed statements of operations for the six months ended June 30, 2018 and 2017 was $12 million and $16 million ( $11 million and $15 million after tax), respectively. The total income tax benefit related to equity-based compensation expense was $1 million for both the six months ended June 30, 2018 and 2017.  The Company expects the future equity-based compensation expense in relation to awards granted and outstanding as of June 30, 2018 will be approximately $61 million.

Diluted income per share is based on the weighted average number of common shares outstanding and the effect of all dilutive common share equivalents during each period.  For the three and six months ended June 30, 2018, the Company had nil and 1 million, respectively, of weighted average common share equivalents, primarily associated with the Company’s stock options, that were excluded from the calculation of diluted income per share. For each of the three and six months ended June 30, 2017, the Company had 2.4 million of weighted average common share equivalents, primarily associated with the Company’s stock options, that were excluded from the calculation of diluted income per share. These were excluded as their inclusion would have been antidilutive as the common shares repurchased from the total assumed proceeds applying the treasury stock method exceed the common shares that would have been issued.

Recently Issued Accounting Pronouncements (Policies)	6 Months Ended

Basis of Presentation [Abstract]
Recently Issued Accounting Pronouncements	Accounting Pronouncements Adopted  Equity-Based Compensation—Modification Accounting  In May 2017, the Financial Accounting Standards Board (the “FASB”) issued guidance clarifying when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This guidance does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and will not be required if the changes are considered non-substantive. The Company adopted the provisions of this guidance prospectively effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Pension  In March 2017, the FASB issued guidance on the presentation of net periodic pension cost and post-retirement benefit cost (“net benefit cost”). The new guidance requires the service cost component of net benefit cost to be presented as part of the other employee compensation costs in operating income, which can be further considered for capitalization as part of the capitalization policy, and to present the other components of net benefit cost, including interest costs, expected return on plan assets and amortization of actuarial gain or loss (the “other components”) separately, in one or more line items, outside of operating income. Further, the new guidance requires a disclosure of the line items that contain the other components of net benefit cost in the footnotes to the financial statements if they are not presented on appropriately described separate lines in the statement of operations. The Company adopted the provisions of this guidance effective January 1, 2018, as required under the guidance, and for the three and six months ended June 30, 2017 , the Company reclassified $1 million and $2 million, respectively, related to the other components from selling, general and administrative expense to other expense within the consolidated condensed statements of operations. The adoption of this guidance did not have an impact on the Company’s net income, consolidated condensed balance sheets or statements of cash flows.  Goodwill Impairment  In January 2017, the FASB issued guidance to simplify the accounting for goodwill impairment. The guidance removes step two of the goodwill impairment test, which requires a hypothetical purchase price allocation. Under this guidance a goodwill impairment is the amount by which a reporting unit’s carrying value exceeds its fair value. The new guidance is applicable for interim and annual reporting periods beginning after December 15, 2019. Early adoption of the amendments in the guidance is permitted for any impairment tests performed after January 1, 2017 and requires its application using a prospective transition method. The Company early adopted the provisions of this guidance effective January 1, 2018. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Restricted Cash  In November 2016, the FASB issued guidance that requires entities to include restricted cash as part of cash and cash equivalents in the statement of cash flows. The guidance also requires a reconciliation of cash, cash equivalents and restricted cash balances disclosed in the balance sheet with the corresponding amounts as shown in the statement of cash flows. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Statement of Cash Flows  In August 2016, the FASB issued guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The amendments provide specific guidance relating to the classification of certain items, including cash payments for debt prepayment or debt extinguishment costs, contingent consideration payments made after a business combination, distributions received from equity method investments and cash flows classification based on its predominate source or use. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.     Financial Instruments  In January 2016, the FASB issued guidance that amends the current guidance on the classification and measurement of financial instr uments. The guidance significantly revises the accounting related to (i) the classification and measurement of investments in equity securities of unconsolidated subsidiaries (other than those accounted for using the equity method of accounting) and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. The guidance also amends certain disclosure requirements associated with the fair value of financial instruments. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have an impact on the Company’s consolidated condensed financial statements.  Revenue Recognition  In May 2014, the FASB issued guidance on revenue from contracts with customers that superseded most current revenue recognition guidance, including industry-specific guidance. The underlying principle of the guidance is to recognize revenue to depict the transfer of goods or services to customers at an amount to which the company expects to be entitled in exchange for those goods or services. The new guidance requires an evaluation of revenue arrangements with customers following a five-step approach: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) the company satisfies each performance obligation. Revenue is recognized when cont rol of the promised services is transferred to the customers in an amount that reflects the expected consideration in exchange for those services. A customer obtains control when it has the ability to direct the use of and obtain the benefits from the services. Other major provisions of the guidance include capitalization of certain contract costs, consideration of the time value of money in the transaction price and allowing estimates of variable consideration to be recognized before contingencies are resolved in certain circumstances. The guidance also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted the provisions of this guidance effective January 1, 2018 as required under the guidance. The adoption of this guidance did not have a material impact on the Company’s consolidated condensed financial statements (see Note 3 – Revenue).
