Not even close. There are only three flights between the two days completely zeroed out, most flights have one or two seats and six flights on the 2nd and two on the 3rd have a combined F/J total of at least 5 available.

Also, as has been stated, many dealers and customers come in early to sell/buy before the official start of the show and if they're already in this weekend some of the customers may be on their way home already.
