I fly very often between EWR and LAX, and I usually fly united. Is there any way to know prior to selecting my flights, which planes will have TVs? (It makes the cross country trip so much easier)!
How about if I don't use a travel agent. (No offense, its usually quicker to just book it myself. No savings to be had using a travel agent IME)
If you use a travel agent, they can tell you ;-)
