Yeah, I noticed a bunch of flights missing (DTW-MCO-DTW) as well for late Aug-Early Sep, although the flights I booked are still booked (they show up in my account, but they no longer show up if i try to book a new res or reprice the existing one). I think they just removed them from being able to be reserved, for now. I figure there is going to be a lot more juggling going on before I ever step foot on the plane for that trip.
