The number of PSMs in the US is boring, and predicted to grow thru 2025+. One of the biggest drivers in the pilot shortage is foreign carriers...their PSMs r forecast to grow at a very fast rate. There are more and more foreign carriers starting us pilot bases....they used to be 0. When emirates/etihad/qatar star us bases and/or commuting contracts for us pilots, along with all hiring in the majors, it will be a huge change.
