A plane may need make an unscheduled landing in the case of a diversion due to mechanical difficulties, unexpected weather, a medical emergency or other reasons (this could even be at an airport with which the operator has no prior agreements).
Airport operators agree various fees with the airlines that use them for their scheduled operations:
- runway/landing fees
- fees for stairs, buses to the terminal building, or airbridges
- passenger charges, should the passengers need to disembark
- parking fees
- ...amongst others
