Has anyone else checked this out? I just did and it was a disaster. "WAS" as a departure airport made me choose between DCA and IAD (BWI wasn't an option) and apparently wouldn't make a fare comparison among the three airports. I chose IAD and asked for IAD-ATL-IAD on DL, TW, or America West (whatever their code is). They had told me Alaska doesn't fly this route. Surprise!!! I don't think America West does, either, and I'm not really sure about TWA. Then I went on hold. Five minutes later, I signed off and sent them a "No Thanks!!!!!" E-mail.
