Can someone who’s up to date with this advise what percentage of a slot has to be operated to avoid losing it under the “use it or lose it rule”. It was traditionally 80% but there was some alleviation under covid and I’m not sure whether it’s now back to 80% or not. Also, does the “use it or lose it” rule apply to remedy slots? I am of course thinking about the LHR remedy slots Flybe uses.
