"What a load of cr@p, and no it's not just because I fly them. They're no older than many other aircraft knocking around in Monarch, Thomas Cook, Thomson etc. and they spend less time airborne, therefore more time on the ground getting some TLC. You won't find many yellow stickers in a Jet2 cockpit."
They may be no older than other UK charter aircraft, but compared to what I usually fly in (Swiss or LH), they are sheds. You can see where the TV screens have been removed and blanked off in a very crude fashion. And usually if you look at what you get for your money on the full service airlines they are not that much more expensive.
