Boeing has had many changes to its aircraft and especially what customer may configure each type. A "mean" has been established with Boeing on its family of aircraft. For many years they have used the same set of numbers for its family of aircraft. Since the 737 Max is being brought forward and the 787 family will reach completion in three years. Boeing is also bringing up-to-date its 777X family of aircraft for both the 777-8X and 777-9X. The data is a thumb nail of the real world of travel and what its customers really expect before purchasing a Boeing product in the listed typical configurations (2015 Assumptions).
A general reduction in distance for each aircraft type is noted over its old scale of which Boeing used for many years. The updated or new data is the effective seat-range relationship it has for all its commercial aircraft. Use this for guidance when considering Boeing's family of aircraft.
