Certainly that rate isn't sustainable but it can only mean better things for those that stay.
BA or the desert lifestyles aren't as attractive as they used to be and commuting contracts in the Far East have far exceeded anything you'll get at Thiefrow or the Sandpit.
I have an 8 mile, 13 minute commute, I do two sectors a day, sometimes I work (but never fly) 6 days in a row but then I get at least 3 off and I do bugger all in the winter, which means I can go and spend a lot of time in another country's summer on full pay. The only time I get close to an FTL limit is when the French or Spanish get their knickers in a twist and go on strike (1 times use of discretion in 4 years). Compare that to BA where you will do 900 hours a year, normally three sector days (enjoy that 2 hour turnaround and visit to the crewroom between flights which makes your day even longer), normally night stop - in a different hotel each night as you do hotel tours around Europe - drive the M25 every other day or commute which used to cost me the better part of 500 quid a month at least. Yeah, yeah I know in 36 years time you'll be earning top scale but I'll be retired long before then and don't care anyway.
Lots of people here whine about management (I presume you think you can do better?) but who cares what they do. I get paid on time every month and have as little to do with management as possible, which is nothing. And no, I don't read Tailwind or the latest department communication.
I go to work, have a laugh, then go home.
Oh, and flying a 25 year old aeroplane is no different to flying a 2 week old one which I used to do regularly. They all break every now and again, it's your job to deal with it.
