Your UCF vs. SMU Football tickets will have assigned seats. If you wish to sit with your student, or guarantee they will be able to attend the game, you should also purchase them a game ticket when you purchase yours.
Student access to football games is available on a first-come, first-served basis and is not guaranteed (the student section has limited seating). Students wanting to attend the game should follow the normal student ticket claim process outlined by UCF Athletics. More information on this can be found here. Student tickets through this process are FREE.
