It would be still nice having that airline offers time of flight, frequency, and equipment (depending on route popularity), CEOs can reject/accept flight like : Air France offers flight :AF8912 which will arrive to your airport at 18:50, refuelling and catering only, stand with jetway, departure at 20:30. If it’s good for CEO he signs contract if not he declines it and airline offers a couple of other variants, for example CEO refused flight which was offered above, now Air France offers AF8912 at 09:10 with same services which are mentioned above and with departure time 11:20. If it’s good he accepts contract and that flight is permanently there unless the route has very bad load they downgrade service for example from 4 times weekly just to 2 If it’s still bad they suspend the flight or airport takes too much money for services and operations route becomes financially unprofitable and as result airline suspends flight to your airport and leaves a bad rating. Every year or 2 airline and airport has to resign contract (time of arrival may differ by CEO likes) also some flight might be set as “Seasonal” like AY1779 from Lyon to Helsinki operated by A319 from 20th December to 20th February and if flight shows more interest then previous year airline might set bigger plane on route or add more frequency from 4 to 5 depends on how much flight interest have grown soon even turning flight from seasonal service to full year service. I hope this idea gets implemented as it adds much more realism than there’s right now by scheduling different flights every time they run out. Thank you
Also smaller prices for services = most likely airline will request them .
