I think the 320A in ATL and NYC will get more senior as they begin to retire the 767-3’s and the MAX10 is delayed until 2027/28.
As the 7ER shrinks to mostly 757s it will do less international and more 3-4 leg days shuffling people in/out of Florida. The appeal of that will wane quickly when the pay on the NEO is the same and the trips are arguably better.
