You are spoiled. There might not be a PTV, but there is a movie! If you don't want to watch what the airline has chosen, you probably won't be that content with 10+ choices the airline made. If it is really that big of a deal to you, bring a laptop or portable DVD player along with your own picks. Or, read the magazine, solve the crossword puzzle, bring a book or newspaper, take a long a gameboy etc. or maybe just bring a sleeping mask so that you will be rested when you arrive!
If you are bent on a PTV, take a detour through HNL
. You won't have it on the six-ish hour flight here, but the 7 1/2 hour top to NRT
will be aboard a PTV equipped 772
BTW this goes in polls & prefs.
