Net proceeds from the seat-license sales go toward construction of the $1.5 billion stadium.

The personal seat licenses are one-time fees required for the right to purchase Falcons season tickets. Prices range from $500 to $5,500 for non-club seats and from $10,000 to $45,000 for club seats. (Club seats are the approximately 7,500 seats that come with access to lounges, dining spaces and other amenities.)

The Falcons have said all seats sold as season tickets will require PSLs. In addition to the one-time license fee, season-ticket prices range from $55 to $385 per game.

Falcons parent company AMB Group announced last month that the stadium's opening has been delayed for a third time because of issues related to the construction of the retractable roof. The current scheduled opening date is Aug. 26 for a Falcons pre-season game against Arizona.
