A few years ago my wife ended up with her leg in plaster two days before my brother's wedding in the New Forest. Doc said ok to fly. Very nice Servisair man arranged wheelchair and when Mrs Guern got to foot of steps of aircraft and found it too difficult to get up them because of weight & size of cast she was upset.
The Servisair member of staff (not being rude but an older gent) said "no problem madam can't have you missing the wedding!" and proceeded to pick her up and carry her up steps. He also made sure that there was someone at the other end to carry her down the steps and stayed with us right to the hire car.
We made a point of writing to them on our return to thank him for his assistance and his colleague in Southampton. Hopefully it was passed on.
Certainly made our day.
