I just finished a 2 hour flight on a UA CRJ700 in E+.

This was the worst airline seat I've ever sat in. My seat bottom and seat back felt like plywood.

Notice to UA: if you made the seat thin and horrid to save space, please give me back a thicker seat in E+ even if you take back a couple inches of my E+ legroom. I'm going to need to start paying more attention to equipment when I book flights. I assume planes that have been retrofitted the most recently have the worst seats.

What an awful awful trend in flying.
