Hi bex88
I can certainly empathise with the work / home lifestyle balance being away is always difficult especially when children are young and everything seems to happen at the weekends, its certainly my biggest challenge since being at BA. Looking at DEC Easy LGW you may as well ask to transfer within BA if that was workable for you. I have a good friend whose been at Easy 9 years a Capt for 4 and hes under 40 and 50% as he just cant stand full time any longer!!
I've used Parental leave at times and it works very well but does take a chunk of money! I'm finding it more and more interesting though that so many people in their 30's / 40's are having to take part-time / parental leave in order to cope in this industry as Full time leaves many feeling utterly exhausted and affecting home life. It just hides the real problem within the industry and the way we are all being worked now!
Best of luck and as someone else said take your time BA isn't going anywhere so you have plenty of time to think.
