The lowest hanging fruit is the current 50-80 seat turboprop market. Next would be the regional jet market and lastly we want to capture a sizeable portion of the single -aisle market. The reason we want to compete with/capture traffic served by 737s and the like is that the market is enormous - we are estimating $1.7T over the next 20 years if we were to replace single-aisle with our 50-seat, SA-1. The reason that we believe we could compete is because we believe that we could bring the CASM of the 50-seater down to be on par with a 737, and combined with the emission reduction we think that this is compelling offer for airlines.
Our aim is not to have to compete with 737s at airports that are slot constrained but to make use of the 100s of underutilised airports across America. By bringing down the CASM of a 50 seater, we believe that this would increase the passenger traffic too and from those airport and make the currently thin routes more profitable.
I see, that makes sense. There's plenty of airlines like Ryan Air and Allegient who operate thin routes to secondary airports. A 50 seater seems perfect for operators who specialize in thin routes. How ironic if budget airlines beat traditional airlines in becoming carbon neeutral.
