I have in on "good authority" from LFFH that only 17 pilots have left in the last year, all of which were young FOs bound for BA long haul and they also think that Jet2 is an employer of choice.
Yes - mainly FO's but also Captains. Only 17? More than 17 alone from MAN have left. They're going to BA, FR, the sand pit. And BA short haul as well as LH. Complete rubbish you have been given "on good authority"
