Yes, a pay/demand equilibrium does require that pilots are willing to relocate - if Wizz is the only show in town, and the pilots are a captive market, then can pay whatever they want (to a point where pilots decide no longer to be pilots or relocate). But in places like Luton, there are normally many many options for pilots, and accordingly, the Wizz Luton terms were not that different to easyJet (and wizz had a much more reasonable type rating scheme)
