Of if they did NONE of those things and moved the exact same number as they move every single Friday afternoon. (I am not saying that is the case - I am simply pointing out that the statistics are totally unclear - and, unlike Superbowl, I see no evidence that the airlines had any more capacity than any other weekday afternoon - this wasn't like a hurricane warning where people might have flooded the airport in larger numbers because they were willing to sleep on the floor for 2 days - these were people with reservations for regular flights).
