What the airport could and should offer are items which have notional value but in actual fact cost either very little or in fact nothing at all. Free parking for passengers and crew.Free parking for idle or repositioning aircraft and free landing fees for them. All of course linked to the number of flights from the airport over the year.
After all it costs the same to have 20 cars in a carpark as it does to have 500 and there are at least 10 stands empty at all times to park aircraft.
Notional values are absolute c**p but can be used to entice any company to the airport.
On past form ,however , Peel would probably give the notional value items away without any contracted undertakings by airlines.
Anyone on the minimum wage should be sacked immediately to save money to pay the senior management.
