Easyjet just aren't interested and never will be
Wouldn't say that's a fair judgement. I'm sure if they could see any potential there they'd do so like any credible airline, and EZY is.
Wizz may well have be operating on behalf of Eastwind hence why they are on the departure board.
Unlikely considering Eastwind ceased trading over 20 years ago. Since "W9" was also their IATA code, far more likely a very old database record never been updated.
