VS have removed the older A343 and only kept a few. these are newer and are fitted with the Odyssey IFE system, featuring 15 movies and several tv channels on a loop. Games and map included.
These a/c were recently reconfigured with the Upper Class Suite, so will most likely last for a few more years at least.
They will most likely be last or not recieve the new PE
upgrade. As of now, only the A346s and Heathrow 747s will recieve the PE
upgrade. This will most likely change.
