New York as a whole has been hit hard by the virus, with 2,382 confirmed positive cases, according to the state’s health department. The state has the second most deaths in the U.S. with 20 compared to Washington state’s 68, according to data from Johns Hopkins University.

New York Gov. Andrew Cuomo (D) has taken several actions to limit the community spread of the virus, including limiting the number of employees in workplaces to no more than 50 percent in an order Wednesday. Cuomo has cautioned that the number of cases may not peak for another 45 days.

Delta spokeswoman Martha Whitt said in a statement that the safety of customers and crew "remain our top priority."

"With regard to reports of any COVID-19 exposure, we continue to follow all guidelines from the CDC and local health officials," she said.
