NBA owners are raking in more cash than before the pandemic by charging higher ticket prices — despite lower TV ratings and increasingly empty seats at arenas, according to internal NBA data exclusively obtained by The Post. The average “gate” per team, or dollars from ticket sales, rose 10.2% compared to the last pre-pandemic season (2018-19) with fans now paying an average of $109 per ticket, according to data from this past season. That’s an 18% increase since 2018-19 and is roughly double the rate of inflation. However, the number of paid fans at arenas plummeted 7.1% to 13,603 per game, the exclusive data also shows. The Post calculated average ticket prices by dividing gate receipts by paid attendance.
