My view would be, subject to the economy not melting down entirely again due to recession/rate rises/high inflation that BA will sooner or later have a bit of a panic about pilot recruitment, much as they are about recruitment for other positions at the moment. Post Brexit there is a smaller number of people with the right to live and work in the UK, and everyone else (easy/ryr/jet2/Tui) etc are going to be competing for these same people. Cadet schemes are a long time in the making. You can’t set them up and have pilots ready 6 or even 12 months later, and I don’t see anyone even talking about setting them up.
In the meantime I’ve lost count of the number of colleagues I speak to who are adamant they aren’t going to go to 65. Honestly, I’m not in the business of giving people false hope and I freely admit there are a lot of unknowns, but it wouldn’t surprise me at all if things started to change very quickly towards the back end of this year.
