Unsurprisingly, single-game tickets have always been in high demand and disappear fast.
Since 2001, they have sold out within the first 15 minutes of the sale's start. Preseason games have sold out within a few days from the beginning of the sale.
After making the playoffs for the fourth straight season and posting a 12-4 record in 2011, the team has continued to see a strong season-ticket renewal rate.
"Once again, well over 99 percent of our permanent seat license owners have renewed their tickets, and they are excited for the 2012 NFL season," Ravens vice president of ticket sales and operations Baker Koppelman said in a statement. "The investment our fans continue to make in us is amazing, and their enthusiasm is remarkable. We greatly appreciate that as an organization."
