Hello fellow flyertalker, I am trying to change an award reservation but the rep said they can't change the class due to the flight is "subject to government approval". They said the system won't let them, even make new reservation on that flight. But I have reservation on the very same flight, so I have a couple of questions.

1) Is it true that they can not change the class or make new reservation on that flight? I can make award reservation for the same flight on all other airline such as Alaska/Qantas/BA...

2) What happen if not approve? anyone experience that route not approve?

3) This is an AA award on partner metal, currently I can't see any award seat available 3+/- the date of my travel, either AA or partner, am I gonna get a refund and left alone? will they put me on a revenue seat on partner airline?
