Also, there are 101 aircraft remaining to be delivered NEW from Airbus on the order books. The fleet in 5 years will be bigger than 101 airframes. I believe there are still 2 320s from Monarch left coming this year.
I'm with DENpilot on this one. The addition of the 321's, and new seats in all three airplanes help lower a fleet wide CASM. There are still plenty of markets that are profitable in the 319- like Trenton, for example. (Not that TTN alone is a reason to keep the 319's, it's just an example.)
Orders, announcements, etc. all point to a mixed fleet of 19's, 20's, and 21's, with a bias towards the larger frames. Someone smarter than me had to have figured out what the right ratio of 19/20/21's was with those skinny seats to drive fleet CASM down to near 5 cents. We just won't see what that ratio is until after they're all delivered, unfortunately.
