Six Flags Entertainment Corporation is an American amusement park company headquartered in Charlotte, North Carolina, United States.

Throughout the 2000s, Six Flags began to suffer from growing debt and organizational bloat, eventually resorting to selling off assets like its European parks and Worlds of Adventure in 2004.

Mike Spanos stepped down in 2021, allowing chairman Selim Bassoul to assume the role of CEO.

For an increased cost, visitors get a wrist band which gives them the ability to wait in a shorter queue for most attractions.

The Flash Pass is an optional, pay-per-person virtual queue system offered at amusement parks operated by Six Flags before the merger.

The system, named after DC Comics character The Flash, allows guests to reserve places in line at participating attractions, and access must be purchased for a nominal fee in addition to the general park admission price.
