American Airlines will pay $90 million over 10 years to sponsor the new home of the NFL's Rams and Chargers, becoming the first official partner for billionaire Stan Kroenke's new Los Angeles Stadium.

American Airlines agreed to sponsor the 2.5-acre space that serves as main entrance to the $5 billion Inglewood, California, stadium, which doesn't have a naming-rights partner yet, according to a person with knowledge of the matter.

American Airlines Plaza stands 10 stories high and has a capacity of about 15,000. It will be open to the public year-round, along with event days. The stadium is scheduled to open next year and host the 2022 Super Bowl. Neither the Rams, which Kroenke also owns, nor American would confirm financial terms of the deal.
