It has been a while since I've been on USAirways and was recently comped to preferred gold - so here I go. Looking at an upcoming trip I am sorting out which seats are best in coach. The online seatmaps for the 757 shows 8F and for the A321 9F with the seat in front removed which I guess makes room for the exit door. It seems like this provides an extraordinary amount of legroom for these seats. Any thoughts on the relative comfort of these seats?
