Because we’re being told it’s all over. Flew to Netherlands three weeks back and lost 25% of pax. Yes a lot were foreign football fans self connecting but at least some were British completely oblivious they needed a test because “it’s in the news we don’t need one”.
It’s far beyond aviation it’s everywhere. It’s back to the December position in town of shops/restaurants with signs in the window opening late, closing early, closed today…staff absences/unforeseen circumstances etc. In-person meetings cancelled. At the local Parkrun attendance was way down yesterday.
