Quote:Boeing is considering an NMA-6X with capacity for 228 passengers and 5,000 nautical miles and a larger NMA-7X which can accommodate 267 passengers and offer 4,200 nautical miles of range, but the design is yet to be finalized.

The 797 family, if green-lit, would not launch until 2025, at which point airlines would have to have made plans to accommodate the rate of growth that the industry faces. Boeing would need commitments to the 797 early on. It may succeed in getting these, with the backing of the original U.S. airlines that are hungry for the plane and some MOU commitments from airlines around the world. But there are still too many unknowns for confidence.
