I am hearing impaired & have spinal stenosis. When I booked my flight I made the airline aware of my handicap. Before leaving the ground, an attendant came to me asking what they could do to make my flight more comfortable. When I arrived at each destination ( I was at 4 with flight to and back) there was a wheelchair with assistant waiting for me. This is the first time I have flown since becoming disabled and I was surprised and delighted with the service I received from Delta.
