4000 hours flying long-haul prior to joining easyJet, never acclimatised to the constant fatigue and jet-lag, hated the 13+ hour overnighters to somewhere I didn't particularly want to go to. Didn't like trying to sleep in the bunk, or in another hotel room in the wrong time zone, trying to be suitably 'rested' prior to the next trip.....Horse for courses but at least I get back to my own bed most nights with easy, don't get jet-lag, and when I'm knackered after my five four sector lates, I get a solid four days rest prior to the next mixed batch of interesting flying
And when I OETD/OETA it's to save fuel that I might need, it's f§@k all to do with airline management muppets
