Being purely slf here, think its a bit harsh saying that jet2 couldn't compete having 20 year old 767 to do an Orlando or Mexico route is no different to some of the older aircraft that BA , or any other carrier send over the Atlantic , thomson still use they're similar aged vintage 767 on USA routes , thomas cook currently using 19 year old 767 , albeit a condor branded one, who use their ageing 767 on vegas routes. Obviously reliability is the key issue, the other issue being which bases would be best for them to dip their toe into long haul?
