planning a trip question i am thinking seriously about maybe going to san diego from washington dulles. what is the cheapeast flight that I might get? Is it cheaper to go to san diego from bwi then dulles to drive up for the cheaper fare at bwi then dulles? I went to united airlines webite and it's line for non stop each way per person is like $ 525 to like $625 I think thats way to much! can i find a fare cheaper then that on southwest?
