Or the demographics of the workforce have changed in such way that workers are from, or at least live permanently in the city they are based in. The trend was that the company turned more and more native with non-locals taking the road leaving the company increasingly locally crewed.
Many view the company, as Narrow Runway pointed out, a place to play the game. It is an excellent stepping stone for the low hour FO and for the FO looking for a quick command. With the local conditions in mind, Wizzair offers a local pilot a chance to be home and if not excellent salary at least a good salary by local standards. For many a night home is worth a lower salary. One can make thousands upon thousands living in China but what good is that if you never see your family or spend majority of your time away from them. Personally I would happily take half the pay to spend double the amount of time home.
For those having a life elsewhere it is far from being a financial bliss and many that left are now making more than double to Wizz salaries with half the workload, again this is mostly people that do not originate from the areas where Wizz have their bases. However there has been some local pilots making a move to other operators outside the region.
As for cabin crew. Many, I would have to say a very large number have found new opportunities in the gulf with the large companies hiring there. Needless to say but the cabin crew salaries while higher than those the Irish wonder provides are still far cry from what a trained CC can earn elsewhere.
