Exactly what they did in Luton, the first flights back after the COVID hibernation were all in direct competition with Wizzair, including that all important TLV route (with Israel’s borders essentially closed at the time, and Israel on the UK’s quarantine list).
I think easy need to learn pretty sharpish that Wizz aren’t just going to go away, before they fritter away even more money.
As for the Wizz vs BA debate. Both offer pretty much the same service on the same aircraft (I believe some of BA’s Gatwick fleet are actually ex-Wizz), Wizz just do it at half the price. The airport would far rather an airline that’s going to use the slots than one that’ll hold on for as long as possible, doing as little as possible.
600 jobs going at Gatwick. A big Wizz expansion would be welcome by all.
