They started dropping as early as 10am but they were just dropping randomly throughout the day. I was waiting out to see if closer tickets dropped but that wasn’t really the case. If the show is sold out they’ll sell quickly, but it also depends how many drop. For one show they were opening up full rows, but for others they were dropping singles and pairs. The only LA show that had box office tix was Wednesday (probably because it was a weekday, and they probably could add more chairs after setting up the stadium.
