My comment got deleted again, hence many haven't seen it, but I shall reiterate so people know where I stand:
I was not putting Jet2 down in any way, I have flown on 3 or 4 of their 757's including their oldest two, 'AG and 'AH... 'AG is my favourite aircraft in the fleet, possibly my favourite 757 and I hope it stays in the LS fleet for a lot longer.
I've also flown on some of their oldest 733's, among others, there is 'CELU, CELX and 4 flights on 'CELO. I also flew on the comparatively young 'GDFK - pre winglets and I couldn't tell any difference at all. Immaculate.
I want to try out a 738 and I'm after 'GDFD, 'GDFF and/or 'GDFJ
