Few pilots wanted to leave EASA so that’s hardly surprising. This whole “you voted for it, sorry” attitude is something else. Regardless of what people voted for few want this mess.
I’m also not entirely sure why those whining about Brits working across Europe are doing so. From what I see theres far more Europeans working in the U.K. than the other way around. If you exclude Ryr and EJ I’d guess there’s all but a handful of Brits working for EU carriers.
