Folks, you are being overly dramatic
I've done DFW-SFO on CR7 in both coach and FC, and it's perfectly fine. The route is too short for a movie on an Airbus, and DirecTV can be OK on 737, but I'd never pay for it in coach.
Bring a book or magazine and catch up on your reading, that's what I do @:-)
And if u/g doesn't clear, I'll take 2-2 seating over 3-3
