I also left BA as a DEP to return to my former loco outfit. Should never have left in the first place. It taught me a valuable lesson not to give up a command chasing the apparent prestige of flying for one’s flag carrier.
Not that it’s a bad job at all. For some it’s fantastic I imagine, but most on my intake are hugely questioning whether to stay or go back.
Good luck to those in the pool though if that’s what you really want.
