Blended Wing Body (BWB) and widebody fuel-efficiency: how efficiency claims depend on density, routes and payload

Leeham News is publishing a multipart series on the Blended Wing Body (BWB), positioning the design as a potentially more fuel-efficient alternative to the tube-and-wing (TAW) layout for passenger airliners. The accompanying fuel-efficiency framing highlights that widebody metrics vary sharply with seating density, route length and payload.
