Talk to you doctor, get a Xanax prescription. Any get an aisle seat. This ain't your doctor's first rodeo, nor is this the first time the flight crew has encountered this. If you need the Crew's s assistance getting an aisle seat, ask them for help. I bet there are at least 3 people immediately close to you on the plane that have the same problem (hint: they are in an aisle set.) They will help you by talking to you,I promise!
