I would try Kayak or ITA Software ( the engine behind it). Not sure if Southwest shows up on Kayak now (didn't used to, so check that ).

Wife and daughter just came back from a marathon 24 hour flight junket. Odessa-Moscow-JFK-Orlando. Just missed the ugliness on Jet Blue. You can't get there (Odessa) from here.
