All airline business plans are written to full fare costings and ops costs - ie we run a spreadsheet on the published tariff - and screw the airports like hell to make the bottom line better but never bank on it.
All of the routes/airports i would like to run - offer a thing called "New route incentives"
The Incentive
If an Airline introduces a Route that is not currently served from the Airport then an All-Inclusive Charge will be payable for each departing Terminal Passenger. This charge will replace the Passenger Facility Charge, Passenger Security Charge, Runway Charge, Air Traffic Sservice Charge and Aircraft Parking Charge.
For Manchester the incentive is for a 3 year term it is £3 in first year 4 in second and 5 in third and full tariff thereafter.
This however does not including handling which for a turbo-prop aircraft is going to be about £200 per rotation.
Keep an eye on KM......
