Being hearing impaired is a challenge to negotiate travel when it was difficult to understand/hear the flight attendants and boarding staff's announcements.

Seat back didn't recline

Check in was easy... once you got to a machine! There was no easy funneling to machines, kind of a free-for-all. And these lines bled into those trying to get to a ticket agent. Some other organization of things should be considered.
