I'm presuming the crunch will come for UK pilots when furlough stops. Which is when the management will be wanting more from the pilots to support the businesses.
Don't be too sure about TUI Biffstick. or any if the big companies, none are too big to fail. Debt has to be repaid and summer 2021 is looking like a none event. There are going to be changes. Now would be a great time to set an airline up, cheap aircraft and crews are everywhere.
