Bears season ticket prices will increase by an average of 4.1 percent for 2019, the team announced Friday.

Prices for Bears season tickets increased only once over the past four years. But after a 12-4 season and an NFC North title in 2018, the team is raising the cost by an average of 5.6 percent for non-club seats and 1.6 percent for club seats.

The Bears continue to follow a demand-based pricing model, with each regular-season game assigned a pricing tier, to be announced along with the NFL schedule in April. Individual-game tickets will continue to cost more than season tickets.

Bears President and CEO Ted Phillips sent a letter to season ticket holders informing them of the increase, which he said was based on analysis of renewal trends and secondary-market data. He also noted the 2019 season will hold special meaning as the team celebrates its 100th season.

The Bears also announced they will go to only mobile-ticket entry in 2019. Printed tickets won’t be issued to season ticket holders or individual-game buyers. Fans must manage their tickets online or on mobile devices, where they also can share or resell tickets.

The Bears also noted that season ticket holders will receive a concession discount through the team’s mobile app.

Peppers retires:Julius Peppers thanked Bears fans and former teammates and coaches — as well as those from the Panthers and Packers — as he announced his retirement from a 17-year NFL career in a letter posted Friday to The Players’ Tribune.

Peppers finished his career with 159 1/2 sacks, fourth-most in NFL history. The defensive end is the only player in with at least 150 sacks and 10 interceptions — he had 11 — and blocked 13 field-goal and extra-point attempts.

Peppers grew up in North Carolina admiring fellow native Michael Jordan and watching the Bulls on WGN, then played for the Tar Heels before the Panthers drafted him in 2002. He saved most of his sentiments for his home state but expressed affinity for Chicago too.

“Bears fans … man … I could not have chosen a better place to make my first stop outside of North Carolina. You were so welcoming and so supportive,” said Peppers, who played for the Bears from 2010-13 after eight seasons in Carolina. “I was very proud to wear that uniform. I’ll always love the city of Chicago.”
