I have just returned from a short break to New York with my disabled mother we had extremely bad experiences at Terminal 4 on arrivals and departures there were four disabled passengers on our flight and assistance had been arranged by out tour operator however the necessary equipment needed to transport wheelchairs from and to the planes were not there and so were kept on the plane (on arrival) and even asked why my mother couldn't walk up the steps to plane and so was taken back to terminal to wait for equipment to be found and put in place. This took 2 hours+ and so resulted in our flight being delayed by 2.5 hrs. the result of which some very unhappy passengers. The disabled passengers were made to feel humiliated and very third rate. I experienced some very miserable extremely rude ignorant unhelpful officials at this airport. and as others have said the immigration process and the security checks are awful no thought is given to those who actually find it difficult and painful to remove shoes coats etc and especially when being hurried and spoken to rudely. Disabled passengers beware - this airport is not disabled friendly.
