Well, this is great, it has helped me a lot. But how about making a button to swap the whole aircraft, instead of route by route? Just replace the aircraft flying the routes; e.g. aircraft ID# 15 gets swapped by aircraft ID# 237, but no change is made to freq. and price.
Maybe this will only be possible with aircraft of the same model, but it will make a great improvement to the game!
Oh, and the issue of Hotswap being available in all worlds, maybe the users that are in the deregulation scenario have hotswap in all the worlds, while others don't have it at all.
