I looked at available tickets for the Arizona game and saw that a single row of seats at the top of section 127 was available for $75 each. It’s a separate section named 127B. They were not available last time I looked but today the whole row was available (they have been snatched up quickly). They also have this at the top of sections 122, 123, and 128, and in the opposite sections mirrored in the south end zone.
It appears that they don’t release these for sale until the stadium is close to selling out. They are not currently available for OSU, Kansas, or Houston games. Why is this? Why is it a separate section? Is this temporary seating that is added on the top row if the game is going to be a sellout?
