There is loose BALPA recognition but my experience of BALPA along with everyone else I talk to about them is they’re useless.
Home UK base £101k plus a few grand more sector pay. Profit share. Private healthcare. Everything paid for like Medical uniform hotels etc. Taxis and hire cars sorted. Unlike Ryanair (my previous) very open base transfer system that works. The odd charter in the winter with stop overs if your lucky. And 450-550 hours a year! Unlike 899:59 in my previous (Ryanair) oh and £10k in the pension pot.
Errrm what’s not to like?
Oh yea and it’s a lot cheaper to live up north than LGW or LHR so factoring that in is massive. Maybe avoid STN.
