Avoid J31's if you're tall
Unless you get exit row, this plane has the worst pitch I've flown ever on in the US. Our plane didn't even have AA paint. I was stunned at both of those little findings.
Today, I was sitting in 2A and had to sit diagonal so my knees/legs were in the aisle as they weren't fitting straight ahead. It was downright uncomfortable.
That being said, the "cockpit" view coming into STL was really, really cool.
