For me personally, I'll start a scam IFS (Making food really expensive - passengers will still pay for it!). I'll also lease until I have around 40 aircraft and enough money- then I'll start purchasing my leased aircraft- I try to go to an airport with a lower lease price than the likes of Heathrow and Beijing Capital but still with good demand - Gatwick is a good example.
How do you all make your money on AE?
