Paid huge sum to park in closest car park. When arrived no disabled parking left and you can't book it. I had to walk way too far almost to back of garage to get to my car in short stay car park 1. In airport there are no self check in machines available for BA to print own boarding cards off for internal flight with no baggage and queues were huge. Security was efficient and did open a short cut for me. But when got to scanner got asked if need my walking stick to walk which to be fair they ask at all airports but I find very offensive as I wouldn't have one if I could walk with out it. Then went into duty free and went to toilet. The door to the toilet when leaving was stuck. So I pulled the alarm cable in the disabled toilet which rang for about 20 minutes without anyone noticing. When the lady did let me out she said they were not sure what it was and that the lock was faulty. Transport to the plane was good and flight was really good and all staff on the flight were lovely. So overall not a great experience.
