I am a new joiner at BA on shorthaul and can honestly say I am enjoying every minute of it.
Compared to my previous aviation experiences (20 years in the military and turbopropping) it is fantastic.
Of course it is not all sweetness and light nowhere is as T's and C's are being eroded across the industry (talk to the guys in the sandpit). It's horses for courses if you want to apply and work for BA go for it, if you don't, don't simple really.
I believe you could put a bunch of pilots in a free bar with free dancing girls/boys and some would complain that it was lager not bitter and blondes not brunettes.
My teacher told me I would never get a job staring out of Windows... How wrong he was !
