Flew US Airways (American) from Phoenix to Des Moines. Knew the flight would be on a regional jet, but was surprised to find the interior hadn't been upgraded since at least America West days. The seats were beaten to death, with every ounce of cushioning worn away over the years. Might as well have spent two hours seated on an bare seat frame - it really was that uncomfortable.
I know there's a big merger and lots of change, but please don't forget that without customers, the whole thing is merely an interesting exercise. Next time, I'll look more closely at the type of aircraft, or just choose another airline entirely.
The upside: flight attendants were pleasant folks, pilots got us there safely and on time, no luggage lost. Flight departed a few minutes late but with the help of a tailwind, delivered us on-time in Des Moines. (Where I promptly found an ice pack to - quite literally - ease the pain in my ass.)
