The U.S. Open welcomed almost 750,000 fans onto its grounds in 2019 during its two-week run, and comparable numbers are expected to attend this year.
But two years ago, there was no coronavirus pandemic. Last year, the tournament was held without fans, and this year the United States Tennis Association will allow them back into what could be one of the most heavily attended mass gatherings in New York since the pandemic began in 2020.
With the tournament set to begin in earnest on Monday, the U.S.T.A. issued protocols for fans and players on Tuesday, and the policies are far more relaxed than they were last year.
