Jetstars option

Virgin has the same seat that Jetstar is looking at ordering but the Jetstar one's will be set up to take the bracket for the iPad. If Virgin was to look at the iPad option I am sure manufacturer BE Aerospace will have some modification that can be done to the back of the seats to allow for this to happen. As has been said in previous posts IFE for airlines is costly for the simple reason it is like any technologies it is outdated the moment you install it. I am sure something will come about eventually and they are possibly observing what QF and JQ are doing at present to make the product better. There was mention a while back that the V Australia business cabin was to be tweaked when they start going for there heavy checks soon, maybe they may make slight tweaks to the economy cabin so that everything falls in to line. Hold in there people I am sure we will find out soon enough.
