The proposed new midsize airplane (NMA) from Boeing, also known as the Boeing 797, promises to bring new capabilities and new benefits to air travel.
In theory, it should slot neatly between the 737 and 787 families, to cater to that middle section of the market.
For passengers, the 797 promises to bring widebody comfort to point to point routes. The 2-3-2 layout will go some way to eliminating the economy crush, with bigger overhead bins and less traffic in the aisle.
There’s a benefit for airlines too. The Boeing 797 is rumored to be able to fly with just one pilot. This means no first officer, thereby halving the salary payable for each flight.
That’s before you get into route optimization, fuel efficiency and all the network planning benefits that the 797 would bring.
