Hi, I had economy flex rtn flight STN-DXB, upgraded to business with miles. STN route cancelled and switched to LHR. The email does not say 'cancellation' but that it's been moved for operational reasons. Clearly the flight from STN has been cancelled. I was hoping to just rearrange for another date in 2021 and keep the business ticket but the agent said I would have to find upgrade availability again? Is that right - doesn't seem fair? Would I not be better just getting a refund of cash and miles instead. If anyone else has had a similar situation please let me know, thank you.
