I need to get to Washington DC in a few months for my future brother-in-law's bachelor party and I was hoping to snag one of the cheap $79 or $99 fares (each way) that Southwest occasionally has to either Dulles or Baltimore (preferably BWI since they have nonstop STL-BWI, IAD would require a stop out of STL). I'm renting a car so I can also visit a friend who lives out in Virginia, so access to public transportation, or lack thereof, isn't important to me, otherwise, I'd be flying into Reagan on one of the other airlines. Right now the fares are about $129 each way. Does anyone know if they lower the fares as it gets closer to the travel date, or have I missed the boat on the ultra-cheap fare? Thanks
