in theory
call TG, don't take 'no' for an answer. Point out their new flight has you arriving after your connection. Tell them, if necessary, that USDM is 'waiting for Thai to put the passenger on the right flight' (ie the 17th).
Basically TG is saying 'we don't have the authority to move your flights as only the booking airline can do that' and 'award tickets can only be changed thru the loyalty program on the ticket' so dumb.... even tho they have moved to a flight that mis connects all my other flights.
They said I need to call USDM back and tell them to get in touch with TG
WHAT A HEAD ****
