Right idea, wrong sequence.
MuseAir (MC) was purchased first by Harold Simmons, then in turn sold to Southwest.
Southwest changed its name to TranStar, painted the planes a rather snazzy dark blue, and moved the HQ to HOU (right near Hobby).

It was to be the long-haul complement to Southwest, but CO cranked up its ops at Hobby as well, and the plan never paid off with returns like WN likes, so it was shut down with little fanfare in (check me on this) 1987.
They were awfully good; MuseAir was especially pleasant in its day, in that they were no smoking when the rest of the 'lines still allowed it.
