Given that most of crew are on furlough they may not have lost many pilots. I would think that given the state of were we are at this present time the likely trawl of a holding pool is very unlikely.
it's just the way things are at the moment. There was I believe some noise about them taking on a apprentice intake, not sure if it was confirmed by anyone.
I hope Jet2 get back into the saddle and start their flying schedules soonest but can't imagine much movement on intake from the pool.
