If you are lucky! Or you might get a broken one or one that has terrible picture quality.
Or, as the majority do, you get a good screen.
You copuld always fly one of the airlines that still only has the centre aisle screens and a choice of, well, no choice, just what they show of course.
Certainly, Nova and Odyssey are not as hi tech as V-Port or the BA system, but many times those flights have problems also with the IFE, plus the media boxes take up room underneath certain seats.
Your parents Cochise, will have a choice of up to eight flims and Tv channels to watch, yes they are on taped loops, but think of the fun swapping channels!
I am sorry, its hardly "crummy" however, much better than many other airlines flying to the USA.
However, if people want to pay much more to get a new IFE system fitted into aircaft that will be leaving the fleet over the next few years, then by all means, tell Virgin you are happy to do this.
