Since they are Frontier press releases they belong on the Frontier site, plus they take a lot of time to put up. I'll look into providing a link to the Frontier press release page from Midwest.

Since this was the part of the sale advertised as the Colorado Day sale it didn't make sense to include starting points outside of Colorado. There was another part to the sale, since it was dual branded, that also included these fares and others from Milwaukee and Kansas City. It just didn't get a press release.
