I used it only last week following major knee surgery. It was really great - we pre booked it via our airline (Easyjet). After checking in we went to the Special Assistance area - we were met almost immediately by a lovely chap with a wheelchair, who took me and the rest of the family through a dedicated check-in - must have been the fastest trip through security ever! They had canes and additional human helpers available at every stage had I needed it to get through the scanner etc. Rather than going to the gate in a buggy he actually wheeled me all the way through the airport - helped with our luggage too (stupidly we'd each bought a cabin bag, which given that I was not going to be able to wheel it myself was a mistake). Someone else took over at the gate - for some reason (presumably health and safety) they insisted that I go right up to the plane door in a wheelchair even though I could walk short distances - but that was fine by me! So I can thoroughly recommend the service.
