Biggio,
I am not sure how much the NCAA actually looks into the individual costs when making a decision, but it is in fact very expensive to fly into Memphis. For some reason the competition flying there is limited so the costs are high. Many of us who flew into the SCAC tournament in Millington flew into Littlerock and drove. We saved about ½ the cost doing this.
I am not really not sure how this is all handled, but thought I would make the point, and also for any fans traveling it is something to consider.
