Midwest Airlines Midwest Miles (Pre-Alignment) - Why does this look familiar?

The GIF image at the bottom of YX's homepage, which promotes the most recent additions to MKE nonstops, looked vaguely familiar. Then it hit me...the layout is very similar to WN's billboards, which promote their MKE nonstops.

Has anyone else noticed the similarity?

Now that you mention it, yes, it does look familiar. The similarity is because they are only showing one or two routes on the map. Southwest has been running an outdoor ad campaign showing just Kansas City and Baltimore on the billboards and buses. The radio ad has also been targeting those two markets. I guess those are the only business destinations and they feel the need to advertise those heavily. They probably figure they'll get good loads on the leisure routes without advertising.
