They kind of have a point - the aircraft they use are hardly state-of-the-art
Blimey if you don't consider 6-7 year old a/c state of the art, what is ?. Those a/c are some of the newest passenger 747's flying in the world today.
If you are reffering to the IFE, let me point out that Lufthansa who are a
national carrier and much much much bigger than VS still don't offer
ANY PTV's in their economy cabins on most of their long haul a/c and still show movies on screens hanging from the roof so you only have 2 option's - watch what they show, or don't - thats it - no changing channels - nothing.
KLM also do not offer PTV's on many of their l/haul a/c either, again showing main screen movies on TV's in the ceiling and thay are reportedly the oldest airline in the world.
What VS do offer on their LGW based a/c is light years ahead of them.
