Rows K - U in section 109 will all have 25 seats, and every row in section 109 starts at 1 from the right (when looking at the court).
Some of the best values on the lower level are found in the corner sections as you will have less obstruction from the basket compared to seats along the baseline, and cheaper ticket prices compared to the center court options.
Thunder fans will have some exciting options in Sections 118 and 119, where the double lettered rows (closer to the court) keep you near the tunnel where the team enters and exits the court. The lowest rows of Sections 112 and 119 are the best places to stay close to the court, with seats at the very front (Row AA) having the feeling of a courtside ticket.
Fans sitting in the back rows (single letters) will be further from the court, but will have the benefit of a well elevated seating height for seeing the court and the closest access to the concourse (tunnels located above the last rows).
