(a) Intangible assets primarily consist of acquired leasehold rights to certain airport owned gates at Chicago’s Midway International Airport, takeoff and landing slots (a “slot” is the right of an air carrier, pursuant to regulations of the Federal Aviation Administration (“FAA”), to operate a takeoff or landing at a specific time at certain airports) at certain domestic slot-controlled airports, and certain intangible assets recognized from the AirTran acquisition. The increase in Intangible assets during 2015 was primarily due to the acquisition of two additional airport gate rights at Dallas Love Field, which were subleased from United Airlines.
