Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Description and Basis of Presentation	Business Description and Basis of Presentation TravelCenters of America LLC, which we refer to as the Company or we, us and our, is a Delaware limited liability company. As of June 30, 2018 , we operated and franchised 533 travel centers, standalone convenience stores and standalone restaurants. Our customers include trucking fleets and their drivers, independent truck drivers, highway and local motorists and casual diners. We also collect rents, royalties and other fees from our tenants and franchisees. We manage our business on the basis of two separately reportable segments, travel centers and convenience stores. See Note 11 for more information about our reportable segments. We have a single travel center located in a foreign country, Canada, that we do not consider material to our operations. As of June 30, 2018 , our business included 257 travel centers in 43 states in the United States, primarily along the U.S. interstate highway system, and the province of Ontario, Canada. Our travel centers included 179 locations operated under the "TravelCenters of America" and "TA" brand names and 78 locations operated under the "Petro Stopping Centers" and "Petro" brand names. Of our 257 travel centers at June 30, 2018 , we owned 31 , we leased 200 , we operated two for a joint venture in which we own a noncontrolling interest and 24 were owned or leased from others by our franchisees. We operated 230 of our travel centers and franchisees operated 27 travel centers, including three we leased to franchisees. Our travel centers offer a broad range of products and services, including diesel fuel and gasoline as well as nonfuel products and services such as truck repair and maintenance services, full service restaurants, quick service restaurants, or QSRs, and various customer amenities. We report this portion of our business as our travel centers segment. As of June 30, 2018 , our business included 230 convenience stores in 11 states in the United States. We operate our convenience stores under the "Minit Mart" brand name. Of these 230 convenience stores at June 30, 2018 , we owned 198 , we leased 29 and we operated three for a joint venture in which we own a noncontrolling interest. Our convenience stores offer gasoline as well as a variety of nonfuel products and services, including coffee, groceries, some fresh foods, and, in many stores, a QSR and/or car wash. We report this portion of our business as our convenience stores segment. As of June 30, 2018 , our business included 46 standalone restaurants in 13 states in the United States operated primarily under the "Quaker Steak & Lube", or QSL, brand name. Of our 46 standalone restaurants at June 30, 2018 , we owned seven , we leased nine , we operated one for a joint venture in which we own a noncontrolling interest and 29 were owned or leased from others by our franchisees. We report this portion of our business within corporate and other in our segment information. The accompanying consolidated financial statements are unaudited. These unaudited interim financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, applicable for interim financial statements. The disclosures presented do not include all the information necessary for complete financial statements in accordance with GAAP. These unaudited interim financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 , or our Annual Report. In the opinion of our management, the accompanying consolidated financial statements include all adjustments, including normal recurring adjustments, considered necessary for a fair presentation. All intercompany transactions and balances have been eliminated. While our revenues are modestly seasonal, the quarterly variations in our operating results may reflect greater seasonal differences because our rent expense and certain other costs do not vary seasonally. For this and other reasons, our operating results for interim periods are not necessarily indicative of the results that may be expected for a full year. Reclassifications. Certain prior year amounts have been reclassified to be consistent with the current year presentation within our consolidated financial statements. Fair Value Measurement Senior Notes We collectively refer to our $110,000 of 8.25% Senior Notes due 2028, our $120,000 of 8.00% Senior Notes due 2029 and our $100,000 of 8.00% Senior Notes due 2030 as our Senior Notes, which are our senior unsecured obligations. We estimate that, based on their trading prices (a Level 1 input), the aggregate fair value of our Senior Notes on June 30, 2018 , was $316,880 . Change in Accounting Principles In May 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers , or ASU 2014-09, which established a comprehensive revenue recognition standard under GAAP for almost all industries. We adopted ASU 2014-09 on January 1, 2018, using the full retrospective method, which required that we restate our consolidated financial statements for prior year comparative periods. Although the majority of our revenue is initiated at the point of sale and was unaffected by this ASU, the implementation of this ASU affected the accounting for our loyalty programs, initial franchise fees and advertising fees received from franchisees. See Note 2 for more information about our revenues. Loyalty programs. Prior to the adoption of ASU 2014-09, we recognized the estimated cost of loyalty awards as a discount against the nonfuel revenues from which the rewards were redeemed. Loyalty awards now are recognized against the revenue that generates the loyalty award, primarily fuel revenue. The adoption of the new standard resulted in a $14,046 and $26,468 reclassification between fuel revenue and nonfuel revenue for the three and six months ended June 30, 2017 , respectively. Initial and renewal franchise fees. Prior to the adoption of ASU 2014-09, we recognized initial franchise fees as revenue at the time the franchisee opened for business, which is when we had fulfilled our initial obligations under the related agreement. Initial and renewal franchise fees now are recognized as revenue over the term of the related franchise agreement, which is the period the customer benefits from use of the franchise rights. The adoption of the new standard resulted in an increase in our accumulated deficit of $1,082 , an increase in other current liabilities of $188 and an increase in other noncurrent liabilities of $894 as of December 31, 2017 , as well as an increase in rent and royalties from franchisees revenue of $43 and $86 for the three and six months ended June 30, 2017 , respectively. Advertising fees. Prior to the adoption of ASU 2014-09, we recognized advertising fees collected from franchisees as a reduction of the related advertising expenses incurred. We now recognize these advertising fees as revenue. The adoption of the new standard for these advertising fees resulted in an increase in each of selling, general and administrative expenses and rent and royalties from franchisees revenue of $422 and $913 for the three and six months ended June 30, 2017 , respectively. Income taxes. As a result of the adjustments described above, a deferred tax asset was recognized, increasing other noncurrent assets and decreasing our accumulated deficit each by $278 as of December 31, 2017 , and decreasing our benefit for income taxes by $16 and $33 for the three and six months ended June 30, 2017 , respectively. The following table presents the effect of the adoption of the new standard on our consolidated balance sheet as of December 31, 2017 : As Reported Adoption of ASU 2014-09 As Adjusted Assets: Other noncurrent assets $ 90,004 $ 278 $ 90,282 Liabilities and Shareholders' Equity: Other current liabilities $ 130,140 $ 188 $ 130,328 Other noncurrent liabilities 35,029 894 35,923 Accumulated deficit (125,416 ) (804 ) (126,220 ) The following table presents the effect of the adoption of the new standard on our consolidated statement of operations and comprehensive loss for the three months ended June 30, 2017 : As Reported Adoption of ASU 2014-09 As Adjusted Revenues: Fuel $ 990,265 $ (14,046 ) $ 976,219 Nonfuel 504,722 14,046 518,768 Rent and royalties from franchisees 4,307 465 4,772 Total revenues 1,499,294 465 1,499,759 Selling, general and administrative expenses 37,877 422 38,299 Loss before income taxes (5,346 ) 43 (5,303 ) Benefit for income taxes 2,380 (16 ) 2,364 Net loss (2,966 ) 27 (2,939 ) Net loss attributable to common shareholders $ (3,013 ) $ 27 $ (2,986 ) The following table presents the effect of the adoption of the new standard on our consolidated statement of operations and comprehensive loss for the six months ended June 30, 2017 : As Reported Adoption of ASU 2014-09 As Adjusted Revenues: Fuel $ 1,925,561 $ (26,468 ) $ 1,899,093 Nonfuel 956,468 26,468 982,936 Rent and royalties from franchisees 8,403 999 9,402 Total revenues 2,890,432 999 2,891,431 Selling, general and administrative expenses 78,689 913 79,602 Loss before income taxes (54,062 ) 86 (53,976 ) Benefit for income taxes 21,695 (33 ) 21,662 Net loss (32,367 ) 53 (32,314 ) Net loss attributable to common shareholders $ (32,437 ) $ 53 $ (32,384 ) The following table presents the effect of the adoption of the new standard on our consolidated statement of cash flows for the six months ended June 30, 2017 : As Reported Adoption of ASU 2014-09 As Adjusted Cash flows from operating activities: Net loss $ (32,367 ) $ 53 $ (32,314 ) Deferred income taxes (23,244 ) 33 (23,211 ) Accounts receivable (8,177 ) (30 ) (8,207 ) Accounts payable and other liabilities 13,427 (56 ) 13,371 Net cash provided by operating activities 15,136 — 15,136 We recognized a net increase in our accumulated deficit at January 1, 2016, of $305 as a result of adopting ASU 2014-09. In January 2017, the FASB issued Accounting Standards Update 2017-04, Intangibles - Goodwill and Other , which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The new standard will apply for annual or interim impairment tests beginning after December 15, 2019, and requires prospective application. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017, and we early adopted this standard during the current reporting period. Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases , or ASU 2016-02, which established a comprehensive lease standard under GAAP for virtually all industries. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification determines whether the lease expense is recognized based on the effective interest method or on a straight line basis over the term of the lease. A lessee is also required to recognize a right of use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales type leases, direct financing leases and operating leases. The new standard will apply for annual periods beginning after December 15, 2018, including interim periods therein, and requires modified retrospective application. Early adoption is permitted. To address implementation of ASU 2016-02 and evaluate its impact on our consolidated financial statements, we have developed a project plan to evaluate our leases, lease classifications and related internal controls. We believe the adoption of this update will have a material impact on our consolidated balance sheets due to the recognition of the lease rights and obligations as assets and liabilities. While the adoption of this standard will have no effect on the cash we pay under our lease agreements, we expect amounts within our statements of operations and comprehensive loss will change materially. In June 2018, the FASB issued Accounting Standards Update 2018-07, Compensation - Stock Compensation , which aligns the accounting for share based payments to non-employees with the accounting for share based payments to employees. The new standard will apply for annual periods beginning after December 15, 2018, including interim periods therein, and requires modified retrospective application. Early adoption is permitted. The implementation of this update is not expected to cause a material change to our consolidated financial statements.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We recognize revenue based on the consideration specified in the contract with the customer, excluding any sales incentives (such as loyalty programs and customer rebates) and amounts collected on behalf of third parties (such as sales and excise taxes). The majority of our revenue is generated at the point of sale in our retail locations. Revenues consist of fuel revenues, nonfuel revenues and rent and royalties from franchisees. Fuel revenues. We recognize fuel revenue and the related costs at the time of sale to customers at our company operated locations. We sell diesel fuel and gasoline to our customers at prices that we establish daily or are indexed to market prices and reset daily. We sell diesel fuel under pricing arrangements with certain customers. For the three and six months ended June 30, 2018 , approximately 83% of our diesel fuel volume was sold at discounts to posted prices under pricing arrangements with our customers, some of which include rebates payable to the customer after the end of the period. Nonfuel revenues. We recognize nonfuel revenue and the related costs at the time of sale to customers at our company operated locations. We sell a variety of nonfuel products and services at stated retail prices in our travel centers, convenience stores and standalone restaurants, as well as through our RoadSquad®, RoadSquad OnSite® and TA Commercial Tire Network™ programs. Truck repair and maintenance goods or services may be sold at discounted pricing under pricing arrangements with certain customers, some of which include rebates payable to the customer after the end of the period. Rent and royalties from franchisees. We recognize franchise royalties and advertising fees from franchisees as revenue monthly based on the franchisees' sales data reported to us. Royalty revenues are contractual as a percentage of the franchisees' revenues and advertising fees are contractual as either a percentage of the franchisees' revenues or as a fixed amount. When we enter into a new franchise agreement or a renewal term with an existing franchisee, the franchisee is required to pay an initial or renewal franchise fee. Initial and renewal franchise fees are recognized as revenue on a straight line basis over the term of the respective franchise agreements. For those travel centers that we lease to a franchisee, we recognize rent revenue on a straight line basis based on the current contractual rent amount. These leases generally specify rent increases each year based on inflation rates for the respective periods or capital improvements we make at the travel center. Because the rent increases related to these factors are contingent upon future events, we recognize the related rent revenue after such events have occurred. Other. Sales incentives and other promotional activities that are recognized as a reduction to revenue include, but are not limited to, the following: • Customer loyalty programs. We offer travel center trucking customers the option to participate in our loyalty program and, beginning July 2018, we offer a loyalty program to our convenience store customers. Our loyalty programs provide customers with the right to earn loyalty awards on qualifying purchases that can be used for discounts on future purchases of goods or services. We apply a relative standalone selling price approach to our outstanding loyalty awards whereby a portion of each sale attributable to the loyalty awards earned is deferred and will be recognized as revenue in the category in which the loyalty awards are redeemed upon the redemption or expiration of the loyalty award. Significant judgment is required to determine the standalone selling price for loyalty awards. Assumptions used in determining the standalone selling price include the historic redemption rate and the use of a weighted average selling price for fuel to calculate the revenue attributable to the loyalty awards. • Customer discounts and rebates. We enter into agreements with certain customers in which we agree to provide discounts on fuel and/or truck service purchases, some of which are structured as rebates payable to the customer after the end of the period. We recognize the cost of discounts against, and in the same period as, the revenue that generated the discounts earned. • Gift cards. We sell branded gift cards. Sales proceeds are recognized as a contract liability; the liability is reduced and revenue is recognized when the gift card subsequently is redeemed for goods or services. Unredeemed gift card balances are recognized as revenue when the possibility of redemption becomes remote. Disaggregation of Revenue We disaggregate our revenue based on the type of customer and type of good or service provided to the customer. Revenues in our travel centers segment generally are earned from highway travelers, while revenues in our convenience stores segment and in corporate and other generally are earned from local customers. Revenues are further disaggregated by fuel revenues and nonfuel revenues within our segment information. See Note 11 for our disaggregation of revenue presented in our segment information. Contract Liabilities Our contract liabilities, which are presented in our consolidated balance sheets in other current and other noncurrent liabilities, primarily include deferred revenue related to our loyalty programs, rebates payable to customers and other deferred revenues. The table below shows the changes in our contract liabilities between periods. Loyalty Programs Other Contract Liabilities Total December 31, 2016 $ 13,686 $ 4,921 $ 18,607 Increases due to unsatisfied performance obligations arising during the period 72,424 11,335 83,759 Revenue recognized from satisfying performance obligations during the period (65,854 ) (10,007 ) (75,861 ) Other (5,091 ) (1,568 ) (6,659 ) December 31, 2017 15,165 4,681 19,846 Increases due to unsatisfied performance obligations arising during the period 39,988 5,106 45,094 Revenue recognized from satisfying performance obligations during the period (36,749 ) (4,791 ) (41,540 ) Other (2,481 ) (702 ) (3,183 ) June 30, 2018 $ 15,923 $ 4,294 $ 20,217 As of June 30, 2018 , we expect the unsatisfied performance obligations relating to these loyalty programs will be satisfied within 12 months . As of June 30, 2018 , the deferred initial and renewal franchise fee revenue expected to be recognized in future periods ranges between $85 and $171 for each of the years 2018 through 2022 .

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill As of June 30, 2018 , and December 31, 2017 , our goodwill balance consisted of the following: June 30, December 31, Travel centers segment $ 21,613 $ 21,613 Convenience stores segment 18,440 69,200 QSL business 3,046 3,046 Total goodwill $ 43,099 $ 93,859 Goodwill Impairment During the second quarter of 2018, we determined that the decline in site level gross margin in excess of site level operating expenses for our convenience stores segment for the three and six months ended June 30, 2018 , as compared to the three and six months ended June 30, 2017, in conjunction with the fact that the operating results for the convenience store segment, since acquisition, failed to meet our forecasted results was an indicator of impairment of the goodwill in our convenience stores reporting unit. Accordingly, we performed an impairment assessment of the goodwill in the convenience stores reporting unit as of May 31, 2018, using the same quantitative analysis approach that we historically followed for our goodwill impairment assessments. Based on the assessment performed, we recorded an impairment charge of $51,500 . Prior to the impairment charge, total assets of the convenience store segment on May 31, 2018, were approximately $466,623 , including $69,940 of goodwill. These analyses require the exercise of significant judgments and estimates, including judgments regarding appropriate discount rates, perpetual growth rates and the timing of expected future cash flows, as well as revenue growth rates and operating cash flow margins, of the reporting unit. As compared to previous goodwill impairment assessments we performed, this most recent assessment utilized a higher discount rate and reflected a lower estimate of comparable market transaction valuation multiples. The fair value estimates are sensitive and actual rates and results may differ materially. Applying different assumptions could lead to different results, possibly materially different.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Environmental Contingencies Extensive environmental laws regulate our operations and properties. These laws may require us to investigate and clean up hazardous substances, including petroleum or natural gas products, released at our owned and leased properties. Governmental entities or third parties may hold us liable for property damage and personal injuries, and for investigation, remediation and monitoring costs incurred in connection with any contamination and regulatory compliance at our locations. We use both underground storage tanks and above ground storage tanks to store petroleum products, natural gas and other hazardous substances at our locations. We must comply with environmental laws regarding tank construction, integrity testing, leak detection and monitoring, overfill and spill control, release reporting and financial assurance for corrective action in the event of a release. At some locations we must also comply with environmental laws relative to vapor recovery or discharges to water. Under the terms of the HPT Leases, we generally have agreed to indemnify HPT for any environmental liabilities related to properties that we lease from HPT and we are required to pay all environmental related expenses incurred in the operation of the leased properties. Under an agreement with Equilon Enterprises LLC doing business as Shell Oil Products U.S., or Shell, we have agreed to indemnify Shell and its affiliates from certain environmental liabilities incurred with respect to our travel centers where Shell has installed natural gas fueling lanes. From time to time we have received, and in the future likely will receive, notices of alleged violations of environmental laws or otherwise have become or will become aware of the need to undertake corrective actions to comply with environmental laws at our locations. Investigatory and remedial actions were, and regularly are, undertaken with respect to releases of hazardous substances at our locations. In some cases we have received, and may receive in the future, contributions to partially offset our environmental costs from insurers, from state funds established for environmental clean up associated with the sale of petroleum products or from indemnitors who agreed to fund certain environmental related costs at locations purchased from those indemnitors. To the extent we incur material amounts for environmental matters for which we do not receive or expect to receive insurance or other third party reimbursement and for which we have not previously recorded a liability, our operating results may be materially adversely affected. In addition, to the extent we fail to comply with environmental laws and regulations, or we become subject to costs and requirements not similarly experienced by our competitors, our competitive position may be harmed. At June 30, 2018 , we had an accrued liability of $3,254 for environmental matters as well as a receivable for expected recoveries of certain of these estimated future expenditures of $500 , resulting in an estimated net amount of $2,754 that we expect to fund in the future. We cannot precisely know the ultimate costs we may incur in connection with currently known environmental related violations, corrective actions, investigation and remediation; however, we do not expect the costs for such matters to be material, individually or in the aggregate, to our financial position or results of operations. We currently have insurance of up to $20,000 per incident and up to $20,000 in the aggregate for certain environmental liabilities, subject, in each case, to certain limitations and deductibles, which expires in June 2021. However, we can provide no assurance that we will be able to maintain similar environmental insurance coverage in the future on acceptable terms. We cannot predict the ultimate effect changing circumstances and changing environmental laws may have on us in the future or the ultimate outcome of matters currently pending. We cannot be certain that contamination presently unknown to us does not exist at our sites, or that a material liability will not be imposed on us in the future. If we discover additional environmental issues, or if government agencies impose additional environmental requirements, increased environmental compliance or remediation expenditures may be required, which could have a material adverse effect on us. Legal Proceedings We are routinely involved in various legal and administrative proceedings, including tax audits, incidental to the ordinary course of our business. Except as set forth below, we do not expect that any litigation or administrative proceedings in which we are presently involved, or of which we are aware, will have a material adverse effect on our business, financial condition, results of operations or cash flows. On November 30, 2016, we filed a complaint, or the Complaint, captioned TA Operating LLC v. Comdata, Inc., et al. C.A. No. 12954-CB (Del. Ch.), in the Court of Chancery of the State of Delaware, or the Court, against Comdata Inc., or Comdata, and its parent company with respect to a notice of termination we received from Comdata on November 3, 2016. Based upon Comdata's assertion that we had breached an agreement under which we agreed to install radio frequency identification, or RFID, technology at our travel centers, or the RFID Agreement, the notice purported to terminate a different agreement between us and Comdata under which we agreed to accept Comdata issued fuel cards through January 2, 2022, for certain purchases by our customers in exchange for fees payable by us to Comdata, or the Merchant Agreement. In the Complaint, we sought, among other things, (a) a declaration that we are not in default under the Merchant Agreement; (b) a judgment that Comdata has breached its contractual duties to us; (c) a judgment that Comdata breached its implied covenant of good faith and fair dealing to us; (d) a judgment that Comdata has and is willfully and knowingly engaged in unfair, abusive and deceptive business practices in the course of its business dealings with us in violation of Tennessee law; (e) an order for specific performance by Comdata of its obligations to us under the Merchant Agreement; (f) injunctive relief; and (g) damages, including attorneys' fees and costs, and further relief as the Court deemed appropriate. At a hearing held on December 14, 2016, the Court denied our request for preliminary injunctive relief subject to Comdata's agreement to continue providing services under the Merchant Agreement pending a final ruling from the Court. On December 21, 2016, Comdata filed a counterclaim alleging that we defaulted under the RFID Agreement and that this alleged default allowed Comdata to terminate both the RFID Agreement and the Merchant Agreement. In addition, from February 1, 2017, until mid-September 2017, Comdata unilaterally withheld increased fees from the transaction settlement payments due to us, during which time the difference between the withheld fees and the fees payable under the Merchant Agreement totaled $6,903 . After a trial in April 2017, and post-trial briefing and argument, on September 11, 2017, the Court issued its post-trial Memorandum Opinion. The Court found that we were entitled to, among other things, an order requiring Comdata to specifically perform under the Merchant Agreement through January 2, 2022, and awarded damages to us and against Comdata for the difference between the higher transaction fees we paid to Comdata since February 1, 2017, and what we would have paid during this period under the fee structure in the Merchant Agreement, plus pre- and post- judgment interest. The Court also found that the Merchant Agreement provided for an award of reasonable attorneys' fees and costs to the prevailing party in a lawsuit enforcing any rights under the Merchant Agreement. We and Comdata reached agreement on the amount of excess fees to be paid to us by Comdata and on the calculation of pre-judgment interest, but did not reach agreement on when final judgment should enter and on the amounts of, or schedule for resolving an award of, attorneys' fees and costs. On October 17, 2017, the Court entered an order outlining a schedule for resolving issues related to attorneys' fees and costs, pursuant to which briefing concluding on January 3, 2018. On April 2, 2018, the Court entered an order granting our application for attorneys' fees and costs and denying Comdata's fee application, or the Fees Opinion. The Court found that we were entitled to an award of attorneys' fees and costs in the amount of $9,844 for the period from September 2016 through November 2017, plus pre- and post-judgment interest, and directed the parties to submit a form of final order and judgment consistent with the Fees Opinion within five business days. We and Comdata reached agreement on a form of final order and judgment, as well as on the calculation of pre- and post-judgment interest and on the additional amount of attorneys' fees and costs to be paid to us by Comdata for the period from December 2017 through mid-April 2018. On April 9, 2018, the Court entered its final order and judgment, or the Order, substantially in the form submitted by the parties earlier that same day. Pursuant to the Order, Comdata is required to continue to honor the terms of the Merchant Agreement and the RFID Agreement and to reimburse us for attorneys' fees and costs, together with interest, in the amount of $10,650 , which we collected in April 2018. For the period from February 1, 2017 through mid-September 2017, we recognized expense of $6,903 related to the excess transaction fees charged by Comdata. In September 2017, we recognized a receivable, with an offsetting reduction of transaction fees expense, of $6,903 for the amount of excess transaction fees we subsequently recovered from Comdata in November 2017. We recognized litigation expenses related to this matter of $37 and $2,527 for the three months ended June 30, 2018 and 2017 , respectively, and $115 and $8,899 for the six months ended June 30, 2018 and 2017 , respectively, which are included in selling, general and administrative expenses in our consolidated statements of operations and comprehensive loss. Our attorneys' fees and costs related to this matter totaled $10,633 through June 30, 2018 . We recognized a $10,082 reduction in selling, general and administrative expenses and $568 of interest income in May 2018 as a result of the Court entering the Order on April 9, 2018, and we collected these amounts from Comdata in April 2018.

Segment Reporting [Abstract]
Segment Information	Segment Information Reportable segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources to an individual segment and in assessing performance. Our separately reportable segments are travel centers and convenience stores. We measure our reportable segments' profitability based on site level gross margin in excess of site level operating expenses. See Note 1 above and Note 15 to the Notes to Consolidated Financial Statements included in Item 15 of our Annual Report for more information about our reportable segments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Segment Reporting	We manage our business on the basis of two separately reportable segments, travel centers and convenience stores. See Note 11 for more information about our reportable segments. We have a single travel center located in a foreign country, Canada, that we do not consider material to our operations.
Basis of Presentation	The accompanying consolidated financial statements are unaudited. These unaudited interim financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, applicable for interim financial statements. The disclosures presented do not include all the information necessary for complete financial statements in accordance with GAAP. These unaudited interim financial statements should be read in conjunction with the consolidated financial statements and notes contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017 , or our Annual Report. In the opinion of our management, the accompanying consolidated financial statements include all adjustments, including normal recurring adjustments, considered necessary for a fair presentation. All intercompany transactions and balances have been eliminated. While our revenues are modestly seasonal, the quarterly variations in our operating results may reflect greater seasonal differences because our rent expense and certain other costs do not vary seasonally. For this and other reasons, our operating results for interim periods are not necessarily indicative of the results that may be expected for a full year.
Reclassifications	Reclassifications. Certain prior year amounts have been reclassified to be consistent with the current year presentation within our consolidated financial statements.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases , or ASU 2016-02, which established a comprehensive lease standard under GAAP for virtually all industries. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification determines whether the lease expense is recognized based on the effective interest method or on a straight line basis over the term of the lease. A lessee is also required to recognize a right of use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new standard requires lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales type leases, direct financing leases and operating leases. The new standard will apply for annual periods beginning after December 15, 2018, including interim periods therein, and requires modified retrospective application. Early adoption is permitted. To address implementation of ASU 2016-02 and evaluate its impact on our consolidated financial statements, we have developed a project plan to evaluate our leases, lease classifications and related internal controls. We believe the adoption of this update will have a material impact on our consolidated balance sheets due to the recognition of the lease rights and obligations as assets and liabilities. While the adoption of this standard will have no effect on the cash we pay under our lease agreements, we expect amounts within our statements of operations and comprehensive loss will change materially. In June 2018, the FASB issued Accounting Standards Update 2018-07, Compensation - Stock Compensation , which aligns the accounting for share based payments to non-employees with the accounting for share based payments to employees. The new standard will apply for annual periods beginning after December 15, 2018, including interim periods therein, and requires modified retrospective application. Early adoption is permitted. The implementation of this update is not expected to cause a material change to our consolidated financial statements. Change in Accounting Principles In May 2014, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers , or ASU 2014-09, which established a comprehensive revenue recognition standard under GAAP for almost all industries. We adopted ASU 2014-09 on January 1, 2018, using the full retrospective method, which required that we restate our consolidated financial statements for prior year comparative periods. Although the majority of our revenue is initiated at the point of sale and was unaffected by this ASU, the implementation of this ASU affected the accounting for our loyalty programs, initial franchise fees and advertising fees received from franchisees. See Note 2 for more information about our revenues. Loyalty programs. Prior to the adoption of ASU 2014-09, we recognized the estimated cost of loyalty awards as a discount against the nonfuel revenues from which the rewards were redeemed. Loyalty awards now are recognized against the revenue that generates the loyalty award, primarily fuel revenue. The adoption of the new standard resulted in a $14,046 and $26,468 reclassification between fuel revenue and nonfuel revenue for the three and six months ended June 30, 2017 , respectively. Initial and renewal franchise fees. Prior to the adoption of ASU 2014-09, we recognized initial franchise fees as revenue at the time the franchisee opened for business, which is when we had fulfilled our initial obligations under the related agreement. Initial and renewal franchise fees now are recognized as revenue over the term of the related franchise agreement, which is the period the customer benefits from use of the franchise rights. The adoption of the new standard resulted in an increase in our accumulated deficit of $1,082 , an increase in other current liabilities of $188 and an increase in other noncurrent liabilities of $894 as of December 31, 2017 , as well as an increase in rent and royalties from franchisees revenue of $43 and $86 for the three and six months ended June 30, 2017 , respectively. Advertising fees. Prior to the adoption of ASU 2014-09, we recognized advertising fees collected from franchisees as a reduction of the related advertising expenses incurred. We now recognize these advertising fees as revenue. The adoption of the new standard for these advertising fees resulted in an increase in each of selling, general and administrative expenses and rent and royalties from franchisees revenue of $422 and $913 for the three and six months ended June 30, 2017 , respectively. Income taxes. As a result of the adjustments described above, a deferred tax asset was recognized, increasing other noncurrent assets and decreasing our accumulated deficit each by $278 as of December 31, 2017 , and decreasing our benefit for income taxes by $16 and $33 for the three and six months ended June 30, 2017 , respectively.
Revenue Recognition	We recognize revenue based on the consideration specified in the contract with the customer, excluding any sales incentives (such as loyalty programs and customer rebates) and amounts collected on behalf of third parties (such as sales and excise taxes). The majority of our revenue is generated at the point of sale in our retail locations. Revenues consist of fuel revenues, nonfuel revenues and rent and royalties from franchisees. Fuel revenues. We recognize fuel revenue and the related costs at the time of sale to customers at our company operated locations. We sell diesel fuel and gasoline to our customers at prices that we establish daily or are indexed to market prices and reset daily. We sell diesel fuel under pricing arrangements with certain customers. For the three and six months ended June 30, 2018 , approximately 83% of our diesel fuel volume was sold at discounts to posted prices under pricing arrangements with our customers, some of which include rebates payable to the customer after the end of the period. Nonfuel revenues. We recognize nonfuel revenue and the related costs at the time of sale to customers at our company operated locations. We sell a variety of nonfuel products and services at stated retail prices in our travel centers, convenience stores and standalone restaurants, as well as through our RoadSquad®, RoadSquad OnSite® and TA Commercial Tire Network™ programs. Truck repair and maintenance goods or services may be sold at discounted pricing under pricing arrangements with certain customers, some of which include rebates payable to the customer after the end of the period. Rent and royalties from franchisees. We recognize franchise royalties and advertising fees from franchisees as revenue monthly based on the franchisees' sales data reported to us. Royalty revenues are contractual as a percentage of the franchisees' revenues and advertising fees are contractual as either a percentage of the franchisees' revenues or as a fixed amount. When we enter into a new franchise agreement or a renewal term with an existing franchisee, the franchisee is required to pay an initial or renewal franchise fee. Initial and renewal franchise fees are recognized as revenue on a straight line basis over the term of the respective franchise agreements. For those travel centers that we lease to a franchisee, we recognize rent revenue on a straight line basis based on the current contractual rent amount. These leases generally specify rent increases each year based on inflation rates for the respective periods or capital improvements we make at the travel center. Because the rent increases related to these factors are contingent upon future events, we recognize the related rent revenue after such events have occurred. Other. Sales incentives and other promotional activities that are recognized as a reduction to revenue include, but are not limited to, the following: • Customer loyalty programs. We offer travel center trucking customers the option to participate in our loyalty program and, beginning July 2018, we offer a loyalty program to our convenience store customers. Our loyalty programs provide customers with the right to earn loyalty awards on qualifying purchases that can be used for discounts on future purchases of goods or services. We apply a relative standalone selling price approach to our outstanding loyalty awards whereby a portion of each sale attributable to the loyalty awards earned is deferred and will be recognized as revenue in the category in which the loyalty awards are redeemed upon the redemption or expiration of the loyalty award. Significant judgment is required to determine the standalone selling price for loyalty awards. Assumptions used in determining the standalone selling price include the historic redemption rate and the use of a weighted average selling price for fuel to calculate the revenue attributable to the loyalty awards. • Customer discounts and rebates. We enter into agreements with certain customers in which we agree to provide discounts on fuel and/or truck service purchases, some of which are structured as rebates payable to the customer after the end of the period. We recognize the cost of discounts against, and in the same period as, the revenue that generated the discounts earned. • Gift cards. We sell branded gift cards. Sales proceeds are recognized as a contract liability; the liability is reduced and revenue is recognized when the gift card subsequently is redeemed for goods or services. Unredeemed gift card balances are recognized as revenue when the possibility of redemption becomes remote.
