crunchie, your post may be confusing to our members because your example concerns airline overbooking, which is considered a separate topic from "delays". Our most recent thread in TravelBuzz on overbooking and DOT proposals is here and members' comments on the DOT overbooking proposal should be added to that thread.

As far as "delays", there is no DOT schedule and if there is compensation or amenities offered, it will vary by reason (ATC and weather delays almost always considered excluded in the U.S.) and by airline.
