interim requirement
Seems logical until it's footprint is fully understood, I am sure that gap will narrow by the time thiese aircraft are in service with volume to have an impact on most airport operations.
Wonder if intruder's imput on the 75 applies, with the 787 we are talking about a wing that maximizes usage of the air that slips off a rigid wing (757) in vortices. With the 778 it's size and displacement of air not just off the wing is an issue.
The quote was interim, no need to get panties in a knot just yet. Doubt boeing would attempt to market an aircraft that would slow down airport ops to this degree at our largest airlines hubs.
