Lucky you....we are flying out of Baltimore and would have preferred DC. Too late for us this round, but how did you find the coupon?

Deal was through google offers on Virgin America. I will probably take SuperShuttle into Fairfax hotel from IAD, try to nap if I get a room, then head up for a long sightseeing day in DC. This will be a little more costly but hopefully more efficient and convenient than all of the bus/metro business during am rush hour.
