Thanks Barb D for the post. Actually the fare out of Dulles is only $128, so just a $10 difference. Well worth the closeness of Dulles to WV. I looked at SW but they only had a 9:00 AM morning flight home, and on Delta out of Dulles I got the 9:00 PM flight home....yeah, almost a whole other day (all non-stops--the only way to fly out of the Wash. DC area).
Because of your post, I have a friend who's been waiting for fly to Tampa on Southwest in Novmeber, she could sure use this information. I'm off to email her!
