Assuming that timeline holds and AA maintains the current schedule, AA will basically need to dedicate almost all A321XLR delivered between 2024-2025 to transcons. The first probably wont fly a revenue flight until Q1 2025 at best, if delivery is scheduled Dec 2024. That means there will be some A321Ts flying until well into 2025, maybe even 2026. They are really falling apart now as AA never refreshed them since delivery ~10 years ago, it's clear AA doesn't want to invest a cent anymore in them, but they still have quite some way to go. So then with dissatisfied premium customers today and gutting corporate sales, who is going to be flying the transcons in premium cabins in 2025, besides perhaps the $242 buy-uppers. Maybe that is AA's eventual reality, to wind down the transcon op to a shell of what it was and focus the A321XLRs on Europe from PHL and CLT. Maybe AA permanently rents slots to B6 or Alaska shockingly picks up JFK-LAX with their new Hawaiian widebodies. (I get the Alaska wish is least likely but that sure would be fun.)
