After flying a transcon last weekend on US. I have an aversion to US. No IFE at all on a 5.5 hour flight. None that I saw in First on their A320s. I was very disappointed. Y is pretty good and F is on par with UA, but still without any IFE and mediocre UA service, not worth a switch IMO. I'd go with AA if I were you. Just to try it out and see how it is.
