I left a major legacy carrier during tough times, contract getting screwed down, seniority not moving anywhere and lots of time away from home, having said that I left due to personal issues and needing to move to the other side of the world due to a family situation. Joined a LCC and got a command in 9 months and was home every night whilst earning more than my spot at the legacy carrier.... good times ;-) Fast forward 10 years and I am still in the Left Seat with said LCC, all of my mates at the legacy carrier also now have commands or very senior FO spots in longhaul and have good control over their lifestyles, they are earning more than me and their conditions I.e pension etc are out of my league. Now the LCC has gone backwards in terms of contract, in this respect all airlines are the same constantly screwing down terms, the roster now comprises 4 and 5 day trips as this is ‘more efficient’ for the company, not a day goes by that I wish I could have stayed with the Legacy carrier, at least there you get some reward for your years of service, at the LCC I am likely to lose my bid in any given month to a 1 day Captain as it is totally random, no one is happy and I can tell you multiple 4 sector domestic days for 10 years is more fatiguing than anything I did at the Legacy carrier. As stated above, be very careful about traded short term angst against your long term prospects, what I would give now just to be able to bid to a long haul fleet for a few years, BA may be a bit hard at times but in terms of fleet choice, work choice and career opportunities you probably won’t beat it.
