These plans include chartered flights for players, limited entourages and of course negative COVID-19 test results before traveling. Furthermore, there would be no spectators, with fewer on-court officials and no locker-room access on practice days.

“All of this is still fluid,” Stacey Allaster, the U.S. Tennis Association’s chief executive for professional tennis, said in a telephone interview Saturday. “We have made no decisions at all.”

If the USTA did decide to go ahead with the tournament, it would occur at it's usual site and time on the calendar.

“We continue to be, I would say, 150% focused on staging a safe environment for conducting a U.S. Open at the Billie Jean King National Tennis Center in New York on our dates. It’s all I wake up -- our team wakes up -- thinking about,” Allaster said. “The idea of an alternative venue, an alternative date ... we've got a responsibility to explore it, but it doesn’t have a lot of momentum.”

An announcement should come from “mid-June to end of June,” Allaster said.

The USTA presented its operational plan to a medical advisory group Friday; now that will be discussed with city, state and federal government officials.

Allaster also addressed other topics, which included proof of a negative COVID-19 test prior to traveling to New York. “Once they come into our, let’s say, ‘U.S. Open world,’” Allaster said, “there will be a combination of daily health questionnaires, daily temperature checks and ... some nasal or saliva or antibody testing.”

Paris, Vienna, Frankfurt, Buenos Aires and Dubai are among the cities where players could catch a flight to John F. Kennedy International Airport on an airline that is a tournament partner. Afterward, players might be taken to where they play next; tournament sites in later September could include Paris, Madrid or Rome.

“A player coming with an entourage of five, six, seven, eight is not something that’s in the plan,” Allaster said. One possibility: Tournaments could provide physiotherapists and masseuses so players don’t bring their own.

Matches could use fewer line judges than usual, with more reliance on line-calling technology. “It’s a hard one,” Allaster said. “Obviously, we want to ensure that we have the highest level of integrity.”

The current plan is to have them -- only adults, no kids.
