So I looked into it more and it looks like AS kept a similar flight, changed the departure/arrival times by 4 minutes but it has a different flight number. Can't imagine they had two exact flights just 4 minutes apart so I guess when they changed it the flight number changed? And so "my" flight is off the schedule but this similar (same) one is still there. The AA leg is still showing on the schedule so I'd like to keep that and just update the first AS leg.
Wasn't sure if there was a different protocol for when the partner changed their leg. There is a more desirable AS flight time that would work but I don't think it was an available awards option before, and it definitely isn't now. I know if it was AA I should be able to change to it but with it being a partner is there restrictions? I'm ok with the same flight times if that's all I get, but if I can get more, why not?
