For the record, this year was the eighth time in eleven opportunities that the Texans have raised ticket prices. The only years that prices weren't raised was in 2003, 2006 and 2011. Ticket prices weren't raised in '06 and '11 because of the poor product put on the field the season before. Ticket prices in 2003 remained the same as in '02 as part of the team's original ticket sales and marketing plan. link
