JFK Redevelopment [Abstract]
JFK Redevelopment	JFK REDEVELOPMENT We are optimizing our international and trans-continental flight schedule and undertaking a redevelopment project at John F. Kennedy International Airport (“JFK”) to facilitate convenient connections for our passengers and improve coordination with our SkyTeam alliance partners. Prior to beginning the redevelopment project, we primarily operated domestic flights out of Terminal 2 and international flights out of Terminal 3 under leases with the Port Authority of New York and New Jersey (“Port Authority”), which operates JFK. In 2013, we completed construction on nine new international widebody gates at Terminal 4, Concourse B, and relocated our operations from Terminal 3 to our new facilities there. In 2014, we substantially completed the demolition of Terminal 3 and began work on the site for ramp paving in order to accommodate new aircraft parking. During 2013, we also announced that we would begin construction of another extension of Terminal 4, Concourse B, for an additional $180 million expansion project that added 11 more regional jet gates. This second extension was completed in January 2015 when we relocated the majority of our regional jet operations from Terminal 2 to Terminal 4. Terminal 4 is operated by JFK International Air Terminal LLC (“IAT”), a private party, under its lease with the Port Authority. In December 2010, the Port Authority issued approximately $800 million principal amount of special project bonds to fund the majority of the project. Also in December 2010, we entered into a 33 year agreement with IAT (“Sublease”) to sublease space in Terminal 4. IAT is unconditionally obligated under its lease with the Port Authority to pay rentals from the revenues it receives from its operation and management of Terminal 4, including, among others, our rental payments under the Sublease, in an amount sufficient to pay principal and interest on the bonds. We do not guarantee payment of the bonds. The balance of the project costs will be provided by Port Authority passenger facility charges, Transportation Security Administration funding and our contributions. Our future rental payments will vary based on our share of total passenger and baggage counts at Terminal 4, the number of gates we occupy in Terminal 4, IAT's actual expenses of operating Terminal 4 and other factors. We are responsible for the management and construction of the project and bear construction risk, including cost overruns. We record an asset for project costs as construction takes place, regardless of funding source. These costs include design fees, labor and construction permits, as well as physical construction costs such as paving, systems, utilities and other costs generally associated with construction projects. The project will also include capitalized interest, based on amounts we spend, calculated based on our weighted average incremental borrowing rate. The related construction obligation is recorded as a liability and is equal to project costs funded by parties other than us. Future rental payments will reduce the construction obligation and result in the recording of interest expense, calculated using the effective interest method. During the construction period, we are also incurring costs for construction site ground rental expense and remediation and abatement activities, which are expensed as incurred. As of December 31, 2014, we have recorded $739 million as a fixed asset, as if we owned the asset, and $733 million as the related construction obligation. We have an equity-method investment in the entity which owns IAT, our sublessor at Terminal 4. The Sublease requires us to pay certain fixed management fees. We determined the investment is a variable interest and assessed whether we have a controlling financial interest in IAT. Our rights under the Sublease, with respect to management of Terminal 4, are consistent with rights granted to an anchor tenant under a standard airport lease. Accordingly, we do not consolidate the entity in which we have an investment in our Consolidated Financial Statements.
