In pay the 767 and 757-300 are not wide-bodies but carry 230ish passengers. The diameter of the tube isn't really relevant anymore. The efficiency of scale is the real measure.

We will not expand traditional "wide-body" routes. Our partners on the other hand are ordering growth airplanes like 787s and 777-300s.
