Pulp, hmm, that's a bit harsh on the pilots who work for Jet2.
Type rated 75 guys only have a 5k bond if they leave before a year, not brill but not the end of the world.
The pay for an F/O is more than you'd get for AEU. Not knocking AEU. Course if you come from Thomas Cook or Virgin then the pay isn't going to be great.
Lastly, most 757's have some sort of thing going wonky on them just due to their age. I think you'd be hard pressed to find a A Class 757 anywhere!
