I think the sale may be over. I just went back on and checked my dates again and they went up to $78 per one way. I didn't see anything about a sale when we ordered our tickets but it did say "special web fare" in red next to the times. When are you leaving? If not for awhile, I'd hang tight. I've been watching the fares for about a month hoping they come down from $89. then they went to $78 to $49. Keep checking. And also check Song air. I think they part of Delta. They have good times and non stops I believe. But i think they fly out of Dulles. Good luck!!!
