If you're interested in seeing the intermediate stops for a future date, possibly after a schedule change, you can go to http://www.southwest.com/cgi-bin/requestSchedule (you can also get there from southwest.com, Travel Tools, Schedules), select Download Schedules for the city in question, then the date range for the date that interests you. You get all the flights to and from that airport; you can either look it over for the flight number, or do a search in the PDF reader for the flight number. You can also use this to determine if the flight is continuing from someplace else.
