What are the chances of getting a complimentary upgrade on this flight? Is it likely to be oversold in WHY? Worst case is I still have my exit row seat (I hope)....
Tis the season for op-ups - as it is every year around late Dec / early Jan due to overbooking in Economy and not many bookings in Business/First.
I'd assume that the flight will be full in economy as they have fully or over booked (as they've effectively closed off bookings).
Will you be lucky? You'll find out on the 20th.
