Re: Boeing examines GEnX powered 767

As others have said, this is a cargo focused study. The 767-300F is in hot demand right now. New, used, it doesn't matter. It is the right sized bird for FEDEX, UPS and Amazon. Between the three of those airlines you are looking at 250+ airframes and blue chip status. Add on the USAF and we are loo...

Re: Boeing examines GEnX powered 767

This seems very much a 767-300F replacement for high-utilization operators (which means UPS, FedEx, and the Amazon army). It wouldn't be competitive with the A330neo, let alone the 787 or a narrowbody, as a passenger frame. But as a freighter it's pretty compelling. How wouldn't it be competitive? ...
