The NEOs are still being planned out, but those would be transcon/HI. Right now, LAX 757 does very little HI flying, so no impact there. The 757 will shift a lot more to hub to hub flying which has already begun. The 757 fleet will be here until 2030 minimum. Only the really old ones will go. LAX and SFO 757 bases are going nowhere for a long time.
