I placed a trip on hold with X miles required. Got a confirmation email, indicating on hold and date of “expiration”. Two days later, I’m ready to finalize booking. Logged into my account and found that the required number of miles was now 2X, double the original amount and unacceptable to me! message indicated I must call the airline to complete the booking. I haven’t done so yet. I suspect they will say something like “sorry, it is 2X miles if you want it”.
I’ve put trips on hold before, booked many trips using award miles, never had a problem. Any advice before I call the airline?
