As always it’s horses for courses. So many factors determine your lifestyle at BA. Do you commute? PP24 or PP34? LH or SH? Which fleet? Age? Family circumstances? Seniority? The answer as to whether you stay or go will be different for everyone at every point on the seniority list for different reasons and nobody is right or wrong.
If you want to be home every night forever then BA is not for you. If you can’t soak up the frustrations of operating out of LHR then I’d avoid it like the plague. For a career in short haul then EZY at a regional base probably beats BA - even at LGW. If you get a command after a few years then the money is certainly better at EZY. But if your goal is to travel the world and spend time in places you would probably never see on your holidays then I can’t think of anywhere else in the UK that can offer the variety than BA.
It’s not a perfect place to work but you can delete those management emails without having to read them and if you never visit Yammer then you’d find life is pretty good because none of the negativity gets through to you! The variety and choice is unmatched but it goes without saying it’s not going to be everyone’s cup of tea. Look after number 1. Too many people are at BA because it impresses the neighbours. They’re often the unhappiest of all.
