2015 - I left easyJet and joined BA on the A320.
I love the job and I'm happy I work for BA (it isn't perfect and its best days are certainly behind it, but name me an airline where this isn't true), overall I'm glad I left easyJet.
Take the negative comments here with a pinch of salt, the problem with most of the bitter old BA pilots is that they've only ever worked for BA and they don't realise how good they've had it, or how good they currently have it.
They'll tell you the 747 is a sh1t fleet to be on, that it used to be fantastic - but if you're joining from easyJet/Ryanair it's still going to be a fantastic experience compared to lugging 180 tracksuit wearing Brits around Europe.
