Although the players and coaching staff make up about 20 people, there are fans and media that will easily fill a mainline jet. Expect to see lots of charter flights with MD-80’s and 737s. I’ve seen Southwest, Allegiant, Delta, USA Jet Airlines and others.
Unfortunately one of the larger charter operators for NCAA 30 seat aircraft has blocked their tail numbers this year. Ultimate Jet Charter carries about half of the teams during March Madness using a fleet of Dornier 328 Jets. All of these trips are booked with a company called Chartersearch who’s sole purpose is to handle NCAA sports travel.
Expressjet will be very busy over the next couple of weeks also.
