Would the airlines really have any question as to whether I could fly? Ive gotten a letter in the reverse- having the doc write a letter for special arrangements (flew across country with a bakers cyst that required elevation of my leg) and I dont think I needed it. We just changed my seat.
I was actually thinking of getting a letter in case they say I cant fly, since I’ll be hit with a cancellation/reschedule fee. But I’ll do everything I can to be in California next week to meet my granddaughter, but dont want to be an inconvenience to them .
