I fly on Navy business pretty often and usually Delta is the line of choice. I've flown AE a couple of times with the same result each time. My butt begins to cramp and otherwise hurt like hell because the passenger seat cushions on the RJ are paper thin . I don't think they have any padding at all. Never had that problem on ASA or Comair connection flights. I'm not looking forward to my return flight this next Sunday. I'll look at getting one of those Nascar stadium seat cushions before my flight.
