SWA 757's
They've studies the idea in the past, but apparently the numbers just don't quite come out to make it a good enough plan. If you can ALWAYS get the good load factors on the 757, it makes lots of $ for you; the problem is that there aren't the markets out there where the LF's are ALWAYS good enough to keep the jets more profitable than the 737's.
Having talked to one of the "old heads" who was part of the team that looked at it, I'm here to tell ya that SWA didn't reject the idea of 757's in Canyon Blue out of hand; the math just didn't quite support it. (Much like they aren't rejecting RJ's out of hand... they're looking at the math, but that's a far cry from claiming that the numbers will support actually buying the smaller jets.)
Very cool photos. Definitely worth reading the website about how he creates the images.
