History

Historical Context

After Dallas voters approved hotel and rental-car taxes in 1998, the Mavericks and Stars moved into the American Airlines Center, which opened on July 17 2001 at a cost of $420 million and secured a naming-rights deal worth $195 million. The arena’s 20,000-seat venue gave the Mavericks a lease lasting until 2031, a factor in Irving City Council arena negotiations that may prompt renewed municipal oversight.
