grounding of leased Airbus A300 aircraft prior to lease expiration, all in connection with announced capacity reductions and included in Special charges in the Consolidated Statements of Operations.
In addition, the Company’s 2008 results included the impact of a pension settlement charge of $103 million for one of the Company’s defined benefit plans included in Wages, salaries and benefits on the Consolidated Statements of Operations.
Revenues 2010 Compared to 2009 The Company’s revenues increased approximately $2.3 billion, or 11.3 percent, to $22.1 billion in 2010 compared to 2009 due to increased traffic and higher average fares.
American’s passenger revenues increased by 11.5 percent, or $1.7 billion, on a capacity (ASM) increase of 1.0 percent.
American’s passenger load factor increased approximately 1.2 points to 81.9 percent and passenger revenue yield per passenger mile increased 8.7 percent to 13.36 cents.
This resulted in an increase in passenger revenue per available seat mile (RASM) of 10.4 percent to 10.94 cents.
In 2010, American derived approximately 60 percent of its passenger revenues from domestic operations and approximately 40 percent from international operations (flights serving international destinations).
Following is additional information regarding American’s domestic and international RASM and capacity:
## Table 0 ##
Regional Affiliates’ passenger revenues, which are based on industry standard proration agreements for flights connecting to American flights, increased $315 million or 15.7 percent as a result of passenger yield increase of 8.4 percent.
Regional Affiliates’ traffic increased 6.7 percent to 8.8 billion revenue passenger miles (RPMs), while capacity increased 5.3 percent to 12.2 billion ASMs, resulting in a 1.0 point increase in passenger load factor to 72.4 percent.
Cargo revenues increased 16.3 percent, or $94 million, primarily as a result of increased volume, particularly in the Latin America and Pacific regions.
Other revenues increased 5.3 percent, or $120 million, to $2.4 billion due to increases in certain passenger service charge volumes and fees and increased revenue associated with the sale of mileage credits in the AAdvantage frequent flyer program.
Operating Expenses 2010 Compared to 2009 The Company’s total operating expenses increased 4.5 percent, or $939 million, to $22 billion in 2010 compared to 2009.
American’s mainline operating expenses per ASM in 2010 increased 3.2 percent compared to 2009 to 12.62 cents.
The increase in operating expense was largely due to a year-over-year increase in fuel prices from $2.01 per gallon in 2009 to $2.31 per gallon in 2010, including the impact of fuel hedging.
Fuel expense was the Company’s second largest single expense category in 2010 and the price increase resulted in $716 million in incremental year-over-year fuel expense in 2010 (based on the year-over-year increase in the average price per gallon multiplied by gallons consumed, inclusive of the impact of fuel hedging).
A return to the recent historically high fuel prices and/or disruptions in the supply of fuel would further materially adversely affect the Company’s financial condition and results of operations.
The remaining increase in operating expense
AMERICAN AIRLINES, INC.  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) temporary, targeted funding relief (subject to certain terms and conditions) for single employer and multiemployer pension plans that suffered significant losses in asset value due to the steep market slide in 2008.
Under the Relief Act, the Company’s 2010 minimum required contribution to its defined benefit pension plans was reduced from $525 million to approximately $460 million.
The following benefit payments, which reflect expected future service as appropriate, are expected to be paid:
## Table 1 ##
During 2008, AMR recorded a settlement charge totaling $103 million related to lump sum distributions from the Company’s defined benefit pension plans to pilots who retired.
Pursuant to U. S.  GAAP, the use of settlement accounting is required if, for a given year, the cost of all settlements exceeds, or is expected to exceed, the sum of the service cost and interest cost components of net periodic pension expense for a plan.
Under settlement accounting, unrecognized plan gains or losses must be recognized immediately in proportion to the percentage reduction of the plan’s projected benefit obligation.11.
Intangible Assets The Company has recorded international slot and route authorities of $708 million and $736 million as of December 31, 2010 and 2009, respectively.
The Company considers these assets indefinite life assets and as a result, they are not amortized but instead are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.
Such triggering events may include significant changes to the Company’s network or capacity, or the implementation of open skies agreements in countries where the Company operates flights.
In the fourth quarter of 2010, the Company performed its annual impairment testing on international slots and routes, at which time the net carrying value was reassessed for recoverability.
It was determined through this annual impairment testing that the fair value of certain international routes in Latin America was less than the carrying value.
Thus, the Company incurred an impairment charge of $28 million to write down the values of these and certain other slots and routes.
As there is minimal market activity for the valuation of routes and international slots and landing rights, the Company measures fair value with inputs using the income approach.
The income approach uses valuation techniques, such as future cash flows, to convert future amounts to a single present discounted amount.
The inputs utilized for these valuations are unobservable and reflect the Company’s assumptions about market participants and what they would use to value the routes and accordingly are considered Level 3 in the fair value hierarchy.
The Company’s unobservable inputs are developed based on the best information available as of December 31, 2010.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF AMERICAN AIRLINES GROUP INC.  broker quotes in a non-active market for valuation of these securities.
The Company’s fuel derivative contracts, which consisted primarily of call options, collars (consisting of a purchased call option and a sold put option) and call spreads (consisting of a purchased call option and a sold call option), are valued using energy and commodity market data which is derived by combining raw inputs with quantitative models and processes to generate forward curves and volatilities.
Heating oil, jet fuel and crude oil were the primary underlying commodities in the hedge portfolio.
No changes in valuation techniques or inputs occurred during the year ended December 31, 2014.

Table of Contents NOTES TO CONSOLIDATED FINANCIAL STATEMENTS OF AMERICAN AIRLINES, INC.
In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances.
In such a case, American may be required to make a lump sum payment to terminate the relevant transaction.
American has general indemnity clauses in many of its airport and other real estate leases where American as lessee indemnifies the lessor (and related parties) against liabilities related to American’s use of the leased property.
Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties.
In addition, American provides environmental indemnities in many of these leases for contamination related to American’s use of the leased property.
Under certain contracts with third parties, American indemnifies the third-party against legal liability arising out of an action by the third-party, or certain other parties.
The terms of these contracts vary and the potential exposure under these indemnities cannot be determined.
American has liability insurance protecting American for some of the obligations it has undertaken under these indemnities.
American is involved in certain claims and litigation related to its operations.
American is also subject to regulatory assessments in the ordinary course of business.
American establishes reserves for litigation and regulatory matters when those matters present loss contingencies that are both probable and can be reasonably estimated.
In the opinion of management, liabilities, if any, arising from these regulatory matters, claims and litigation will not have a material adverse effect on American’s consolidated financial position, results of operations, or cash flows, after consideration of available insurance.
As of December 31, 2015, American had issued guarantees covering AAG’s $750 million aggregate principal amount of 5.50% senior notes due 2019, $500 million aggregate principal amount of 6.125% senior notes due 2018 and $500 million aggregate principal amount of 4.625% senior notes due 2020.
(h) Other As a result of the terrorist attacks of September 11, 2001 (the Terrorist Attacks) and the subsequent liability protections provided for by the Air Transportation Safety and System Stabilization Act (the Stabilization Act), American recorded a liability for the Terrorist Attacks claims equal to the related insurance receivable due to American.
The Stabilization Act provides that, notwithstanding any other provision of law, liability for all claims, whether compensatory or punitive, arising from the Terrorist Attacks, against any air carrier shall not exceed the liability coverage maintained by the air carrier.
As of December 31, 2015, the remaining liability and the amount of the offsetting receivable were each $974 million.14.
