Direct flights to Hobby Airport from Chicago besides SW

I apologize if this is not the right place to ask, but I'm trying to get a direct flight to Hobby Airport in January. I need it to be an afternoon flight. Is Southwest the only airline that flies directly to Hobby from Chicago? I only see SW flights from Midway (which also is a big negative as I am closer to O'Hare). No other airline. IAH has plenty of flights but we are doing an overnight before flying out of Hobby the next morning. Any help is appreciated.
