Finally some good news for Cardiff after a pretty horrendous 12 months with Covid and the losses of BE and TCX.
Interesting that Wizz's first two non-London bases are small airports where they will be able to rule the roost as it were. Quite sensible that they are sticking to bucket and spade routes which have proven records from small British airports (even CWL). The only notable exception is Malaga, but it seems possible they might have wanted to avoid a route with three airlines already. I imagine we might have had a bit of Eastern Europe (OTP/KRK/WAW/GDK/BUD) like DSA if it wasn't for the uncertainty of Brexit and likely fall in migrant workflows. Perhaps that's something to look for in the future.
I can't imagine WIzz ever launching routes domestically or to Ireland either. As others have said, Aer Lingus Regional, Eastern, new Flybe and Loganair are the more likely operators when the Covid mist rises.
