Airlines

Airlines are the entities that own the planes that use your airport. By signing a contract with an airline, you are agreeing to service their planes by facilitating:


 * Deboarding
 * Baggage unloading
 * Refuelling (if requested)
 * Maintenance (only if emergency)
 * Cleaning (if requested)
 * Catering (if requested)
 * Baggage loading (if requested)
 * Boarding
 * Push-back (requested for all medium and large planes)
 * Deicing (requested when temperatures near sub-zero degrees)

This process is outlined as in the signed airline contract.

Contracts
Airlines need signed contracts before they will conduct any form of business with you. As your airport's reputation grows, you will have access to bigger and more lucrative contracts. Once a contract is signed, you will receive the agreed commission per passenger that boards or deplanes at your airport as per the signed airline contract. They can also dictate of which services they would like to take advantage of and in turn pay your airport for said services as below.

Services
Planes that have landed will be able to make use of whatever services your airport offers, such as refueling, cleaning, and storage-as per the signed airline contract. You will receive payment for the use of such services, as agreed in the signed airline contract.
