CPB
Well, I think it a shame that you think BA as an employer leaves a lot to be desired <<because>> they took over your previous employer. That seems like sour grapes. I had hoped your use of the word "since" would have been "from the point when". Oh well.
Obviously this is subjective, and I am quite prepared to accept that you'd rather not fly for BA given the choice; but I resigned from a very stable, solid UK airline to go to BA and have never once regretted it. I would never in a million years make a different decision given my time again - and for me that is the acid test. I consider myself very lucky to be where I am.
One can only observe as one finds - and I wish Lupin all the luck in the world in following his own choice - but I would endorse it if he sought my opinion, FWIW.
Ciao,
