Sooner fans started arriving by the hundreds at Chicago's Midway Airport Thursday, more than 48 hours before Saturday's showdown with Notre Dame.
The University of Oklahoma Alumni Association chartered a plane for fans and filled four commercial flights with OU faithful.
"Two of the greatest traditions in college football, we just had to be a part of it," said Sooner fan Mike Jones of Norman.
The OU Alumni Association booked two hotels in downtown Chicago to accommodate all the Sooner fans who made the trip from Oklahoma.
"The interest in this trip has been tremendous," said Brian Cockerham, vice president of Prime Sport, the company contracted by OU to handle fan travel.
A 'Boomer Bash' is scheduled for the House of Blues in downtown Chicago Friday night. The OU Alumni Association scheduled other activities for Sooner fans in Chicago leading up to Saturday's big game.
"It was cool to see all the crimson and cream at the airport," said OU fan Courtlyn Shoate.
Sooner fans say despite all the extracurricular activities surrounding the game, ultimately they made the trip to see Oklahoma win the game.
"I could walk home if OU won," said Maria Baggett of Norman. "It would be worth it. I'd be smiling all the way home."
