Based airlines
No airport like base operators.....
1. They want to park their smelly aircraft all over the nice new concrete, blocking aprons & terminal stands.
2. They want office space, staff car parking & complain if they have to park too far away.
3. They want discounts on fees.
4. They want to maintain aircraft with those maintenance people, well there the worst, wanting to go and run their engines and annoy all the airport neighbours......
The airport ideal, as stated, is an airline based somewherelse, who only wants to land, park for 30-40 minutes and then departs.
