Top executives at global airlines and lessors, including many who were thought to be likely large launch carriers for the NMA (which would eventually become the 797), have soured on the idea of Boeing’s 220 to 270-seat twin-aisle concept and are privately pushing for a successor to the 737 Max and the aging fleet of 757s
Behind the scenes, Boeing has been recently briefing a small handful of U.S., European and leasing customers on an all-new aircraft — dubbed the Future Small Airplane (FSA) — whose first models would notionally be 180 to 210-seats. That’s larger than the 737 Max 8, which seats 162 passengers in a two-class configuration.
There is a paywall.
I find it very interesting airlines are pushing for FSA over the NMA.
