Wizz will stay at Cardiff if flights are profitable enough for them to. There are certainly a large enough number of passengers in the catchment area. Not far off 2 million travel over the bridge to BRS each year to fly. The real question is if Wizz can capture enough of them/ generate enough new passengers at the right price. Nobody knows if that will be the case yet.
They do have a history of starting and cutting routes frequently - but that is always going to be the case when you have an airline expanding as rapidly as Wizz are. They do sell seats through travel agents on package holidays as well to the person who said they didn't.
fanrailuk Yes, the same was said about Vueling. The thing your flippant comment forgets is that they have spent *a lot* of money on marketing. That's got them passengers all right, but they've cut flights they used to operate and still carry fewer Welsh passengers to AGP/ PMI/ ALC than easyjet and Ryanair do from Bristol. When people in S. Wales think of a LCC, they think easyjet and Ryanair, not Vueling and that's just a fact. That's not to put Vueling down of course. They have done an excellent job cutting out a niche at Cardiff.
As for domestic routes, lets see what happens when the Covid mist thins (hopefully) over the summer. Wizz isn't going to be operating any domestic routes, but there are other possible carriers that I listed a few posts ago.
