Good advice above. I know it is obvious to most, but some may need reminding that this is only a way of earning to money to live. If you can make the job work for you and enjoy it at the same time, then you will never work a day in your life.
BA isn’t for everybody. Those that are here seem to enjoy the job, or at least pretend to. The only problem is spending too much time at work enjoying yourself. Hence the old cliché of the BA skipper on his/her third spouse. It can be difficult holding down a home life as the long haul part of the job is great fun, if tiring, staying in pretty decent hotels with like-minded people, especially now legacy crews are on the decline. The danger is it is possible to treat the job as one long holiday, to the detriment of loved ones at home.
