My wife has difficulty walking and particularly climbing stairs. We contacted Virgin Airlines to see what service they could offer to make it easier for my wife to board and leave the aircraft.
When we booked in, an Virgin attendant arranged for a wheel chair, so that my wife would not have to walk the considerable distance to the Departure Gate.
We were given priority when it was time to board and she was pushed to a small lift beside the aircraft and stepped off to board. We were allocated seats at the front, with a little more leg room. After an enjoyable flight, the same courtesy was extended to my wife in Hobart.
Our return flight to Sydney, she enjoyed the same consideration. I might add that another lady, with difficulty walking, enjoyed the same courtesy.
