I didn’t like that the seats are sooo small on these planes. Also I was a disabled passenger who wrote to the airlines requesting special assistance and still had to climb steps to get into a prop job. Then at my connection the wheelchair person only took me to the drive way and made my husband take me the rest of the way through the airport. Wheelchair assist was disorganized.
