Tickets are sold by Ticket Zone. Your exact section, row, and seat will be assigned and loaded into your account before your game — you’ll get a notification when the location is visible.
All tickets in the same order will be seated together. In some cases, one or two seats may be placed slightly behind the rest of your group but will still be in the same general area. Seats that are transferred out of the account prior to seating assignments are not guaranteed to be seated with the original order.
