Recently I flew with
British Airways.
They seem to have recently made commitment to provide accessible experience to passengers with special needs.
At any case, when checking in for flights, I was now asked if I need special assistance. The accessibility program seems to be relatively new - they now know how to deal with passengers with difficulties in walking, but deaf passengers are relatively new experience for them. So I had my turn at educating the airline employees that deaf passengers need a way to see the captain's messages in writing, especially in emergencies.
The airplanes, in which I flew both directions, had plasma TVs for each seat. However the video programs were suspended whenever there were announcements - with no written rendition of the announcements. This is something, which can be improved.
An hilarious experience was when the airplane neared landing. I was asked by two stewards if I need assistance. I explained that I'll need assistance, only if we crash land, and the captain gives instructions to the passengers. We all laughed.
