The only thing that will tempt people to take the risk of a new startup airline, based in an undeveloped construction site in the desert without alcohol....is flexible commuting, part-time contracts, or a harem of crew girls.
Without this, they need to offer $20-30k+ a month to get serious candidates. Even if only on a 3-year contract for ppl who want to top up their pension before retirement. Consider Emirates and Qatar are struggling to find new joiners for future growth with $15-20k/month packages, after having already scraped the barrel worldwide from every ****hole possible.
Yes, you may get a few desperados. But the risk of RIA going belly up, being fired, contract changed, fleet changed, housing debacles, major incidents, no expat lifestyle, or just a general mess/nightmare of an organisation dictate a large premium in cash or conditions.
Failing that, a training airline, with a complete focus on 0hr cadets like Wizzair/Ryanair etc. If you offer $10k a month tax free to young graduates, they could take it as a stepping stone. DEC's with no P1 time etc.
