I have a replacement hip and knee and have recently developed spinal problems. We are booked on a trip from BDX to LGW and onwards to LAX in January which is all paid for. Therefore we are reluctant to cancel although I can only walk a few steps. Has anyone experience of the wheelchair services of BA both in the UK and in Los Angeles please? I am concerned that my husband will be left with all the luggage and managing everything on his own!
