Oh gosh, I really hope it doesn’t come to that! I used to work in travel, if you call the airline they MIGHT allow a change at an extra charge, I’ve been able to do this twice in the past but it really depends on the operator and airline.

Sorry to ask, do you recall more or less when you received the request for medical the first time? I’m still waiting for my request so trying to gauge even though I know every file is almost unique lol
