The relationship between the airlines and the airport is formalized by one form of contractual agreements. These agreements address operational issues such as the use and leasing of land and terminals, facility development, insurance requirements, other authorized uses and reporting of airline operational activities at the airport. This may include landing information, passenger and cargo information, aircraft parking and refueling. A flight agreement may also allow an airline to create an account for the payment of financial obligations at the airport. All airport users operating aircraft up to or more than 6,000 pounds Certified Maximum Gross Take-Off Weight (CMGTW) must report their landing declarations and pay the corresponding landing fee. Different types of flight agreements are available depending on the size of the aircraft, the frequency of flights and the offers offered. There are also different fares for signatory and non-signatory airlines. Airport staff are available to help determine the form or forms (s) of the convention (s) that are appropriate for your proposed operation. Opportunities for airline operations in the Alaska International Airport system exist at many levels, from local pilots, air taxis and charter services to domestic and international passenger and air cargo operations.
