Why woold codeshare from dfw not available to california colorado florida. All southwest have to do is put those routes in computer. I know it long way but if somebody want to fly it why not give this option to pasangers?

As I understand it, for ATA flights to be bookable on SWA's site, either one segment needs to be on WN or, as of this month, one can book a single segment on ATA, such as DFW-MDW, but not a connection with two segments both on ATA. I'm not sure of the reasoning behind this; maybe ATA doesn't want to allow this, but that's how it is.

I guess your main point is that WN doesn't show connections to these states even on connections to WN at MDW. WN does seem to avoid listing out-of-the-way connections, but they aren't always consistent about that.

They also don't publish DTW-MDW-DCA or DTW-MDW-LGA, which would involve a lot less backtracking than DFW-MDW-SFO. (And they *do* publish DTW-MDW-BWI and DTW-MDW-ISP.)
