What does it makes sense to pre order aircraft? There is no difference between ordering an aircraft 1 year before its launch date or ordering it 1 day before, right?
There is actually a few pros to preordering aircraft. One is that if you're quick enough, your airline could become the launch customer of that aircraft in that world, like how my airline, Paw Airways International, is the launch customer of the Bristol Britannia. Another good thing about preordering an aircraft is that over time, you can invest more and more into either leasing or buying them before the first delivery. This way then overtime as your airline continues to make more money, you can invest into a greater amount of aircraft, and you don't have to wait so long after you ordered your aircraft. Once production begins, they'll start rolling in one after the other every two or three weeks, or whatever the delivery rate is.
