Boeing Canada announces Boeing Sonic Cruiser

[SWAFO]

I doubt SWA will replace the 737 with the 787. As John mentioned, the 787 is a bit larger. Designed to replace the 757/767. I believe that
the 737 line of aircraft (the best selling line ever), will continue. Boeing's not going to give up their most successful design. They'll most
likely fix some of the things that bug us pilots in the next generation series, add a few extra goodies, and release another 737 version!
