Winter Meetings
Each year during offseason, Winter Meetings occur, wherein all of the teams' management gathers for discussions on the state of baseball. In OOTP, this is the time the GM should set their ticket prices for the next season for the sale of Season Tickets. This can be set BEFORE Winter Meetings or During Winter Meetings. Once Winter Meetings are over, your ticket prices will be locked until Opening Day.

To change your ticket prices you want to go to the Front Office of your teams menu. Team menu >> Front Office. You will find the Ticket Price section on the left hand side of the page in the middle.
