This thread is like a commercial for AA More Room in Coach!
I actually just flew my first flight with AA More Room, and it was wonderful. No knocking elbows or knees. The seat in front of me was reclined, and I didn't even notice it. It's a whole new realm of coach travel.
But for those other times in coach (like the time I braved Frontier Airlines, ugh!), seat kickers make everything miserable. But vodka makes everything better!
