Aerospace company Boeing and NASA are bringing five airlines on board in their efforts to make a more environmentally-friendly single-aisle passenger aircraft Seattle-based Boeing said the airlines would help with the development of the NASA-backed X66-A aircraft, for which a new livery was unveiled on July 25. The carriers include the so-called US “big four” – American Airlines, Delta Air Lines, Southwest Airlines and United Airlines – as well as Alaska Airlines, a major player in US west coast cities such as Seattle. The carriers are to “provide input on operational efficiencies, maintenance, handling characteristics and airport compatibility,” according to Boeing.
