since we don't know a lot of the particulars of your flight im going to assume that its getting close to a full day for the crew of your flight to continue on...with out a crew break....I have been on a few flights in north America where the crew got off at ohare,atlanta and dallas and proceeded to take a crew break(meal) later in the day I can see this versus a full out crew rest which to me means a 8hr layover, I hope its a crew break for your sake.
