The whole 320 fleet will have new seatback entertainment by end of the month. The 321 flying is more and more 3-5 hour legs from east to west. If you're an East coaster, the 320 does a lot of north-south coastal flying, 319s doing many long-thin routes. Redeyes are increasing with more 321s. Still got 162-262 321s to be delivered. LAX base will be on Spring AE. Strong chance of SEA in future years. Expect Hawaii beyond 2020.
Most importantly, I'm scared constantly because I don't have control of the jet. Senior bidders beware!
