We should be worried for the entire industry right now and how it will change in the next 3 years, and not worried about a few Aussies. SWA just announced they are hiring 800 pilots yet this year. United, Delta and American will soon be following suit. There just aren't that many US pilots out there --- the numbers in training is abysmal.
When small cities start losing their air service due to the lack of pilots, Congress will raise retirement ages, small and weak regionals will be bought by the majors to acquire pilots, or a flood of immigrant pilots will be let in. None of this is particularly appealing for any SKW FO. It will either keep us in the right seat for a few more years, give priority to other regional pilots in advancing to the majors, or suppress our income.
SKW is hiring a few (<10%) foreign pilots with a US visa. (The current SKW requirement is a passport with a work visa.) Envoy is hiring Army and Marine rotorheads with 750 hours and sending them to San Marcos for fixed wing training. If you see SKW and a Envoy doing that, they are taking extraordinary steps to keep a pilot supply. They are concerned and significant changes to both the industry and pilots are coming, and change probably not to our liking. If you think the Trump administration will stop pilot immigration to raise our wages, you are kidding yourself. I believe the Trump administration will do the opposite and all those Indian and Chinese pilots you see if flight schools these days will be shortly flying regional routes in the US.
