Soldier Field has two types of seating - "PSL" and "non-PSL". PSL stands for "Permanent Seat License", which in exchange for a one-time fee gives the license holder permanent control of the rights to season tickets for a specific seat, including the right to transfer or sell the "PSL". Non-PSL seats do not require a separate one-time license fee, but the rights to non-PSL season tickets cannot be transferred – the seats must remain under the name of the original account holder for as long as that individual or company buys the season tickets.
