Get somebody to wheel you to and from the plane. If you don't have a wheelchair, the airport can provide one if you arrange it ahead of time. Airports are usually really long walks.
Thanks. I forgot to ask for that but i got a business class ticket hoping that i will be able to have more rest there.. I think they will provide a bus for transfers.Hope that will help. best wishes.
Yeah, walking around the airports and standing in lines is hell. The actual ride isn't as bad. If your OI isn't under control, I really strongly suggest a wheelchair unless you know the lines are short at the airport.
