they can try and bid it out, but most regional airlines with common sense would staff up now, since the going rate to recruit serious numbers of pilots right now is 500/50-800/100 time wise. With rest times and these mins they will need to staff up now, or else actually pay people later. AMR might make a big dumb moving, by playing the cards of 5 years ago and bidding out feed, just to find they dismantle Eagle and then have to go out and buy a regional in the future with a flow up agreement. That would be because thats the only way people will go to regionals.
