No idea, but with 8,000 more new hires coming in the next 3-4 years only the majors (United, Delta, American, Southwest) will have pilots. Most hires at the small carriers and regionals are only replacing pilots leaving for the 4 majors. The LCCs are going to be drained of pilots and that will limit their growth. Plus good luck buying planes for the next 5 years.

By the end of 2025 a pilot hired at United in 2021 will have 10,000 pilots junior to them.
