JTFrogger: Did you happen to book Sep 20 to 27 by chance?
I just talked with a friend who booked 2 dates, one departed on Sep 20 and one departed on Sep 21.
His Sep 20 departure got cancelled, so he called Orbitz, and they explained that the Sep 20 flight really was full, but that his Sep 21 departure is fine, real, and valid (this is what they say anyways).
EDIT: NM I see you booked 7th-14th. This thread is going too fast
