October 11, 2018, © Leeham News.: The Boeing NMA is by now reasonably well defined. The passenger capacity is set at 225 seats for the smaller version and 265 seats for the larger. The nominal range is 5,000nm for the smaller version and 4,750nm for the larger NMA.

This is all nominal data. In practice, there will be different operational realities which will decrease these figures. How much and how useful will the final operational NMA be? What will be the economic advantage over the direct competition?

To find out, we will pit the NMA against its direct competition in a series of articles.


  • The NMA as defined is configured according to Boeing's STANDARD rule set. Using these rules, the smaller variant is classified as a 225 seat airliner with a range of 5,000nm. The larger as a 265 seat aircraft with a 4,500nm range.
  • In practice, operational realities and cabins changes compared with the ones used in the STANDARD ruleset will decrease the seating capacity of the aircraft and its range. How much and why is discussed in this, the first article in the series.
