When Wizz started to use Luton all the flights were from the airports the other end that they operated to. They were asked many times when will they open a base at luton and for a very long time Wizz were against any kind of base at UK airports.The only thing i can see that changed their mind was the UK pulling out of Europe. Wizz as like any airline it takes a lot of funds to start up a base and they must be prepared to lose a lot of money to start with but if lucky make money from the start.I cant see any problem Wizz to use CWL but operated from the other end,but as time goes on open a base at CWLonce they have their brand name in peoples thoughts.If they did start to operate into CWL and operated from the other end there is less risk of it failing as no outlay regards a base costs.
