An American Airlines baggage handler at DFW International Airport left work this week after being diagnosed with COVID-19, raising the total to three company employees now out with the fast-spreading virus.

The baggage handler has not worked in several days and notified the Fort Worth-based airline of the diagnosis this week, according to a source close to the company.

On Friday, leaders at American and its regional carrier Envoy sent letters to airport employees warning them about the case and urging them to follow Centers for Disease Control and Prevention recommendations to stay home and seek medical attention if they show symptoms, according to memos shared with The Dallas Morning News.

American spokesman Joshua Freed declined to confirm Saturday whether any baggage handlers were diagnosed with the COVID-19 coronavirus.

“The safety of our customers and team members is our top priority," said a statement from Freed. "We are in close contact with the CDC and public health departments and are coordinating with them on all required health and safety measures.”

As the number of confirmed cases of the coronavirus increased in North Texas this week, so did the breadth of workers impacted, from a restaurant worker to police officers. Nationwide, professional basketball players, actors and doctors have reported that they were diagnosed with the virus.

American Airlines has about 33,000 employees at DFW International Airport and its nearby headquarters campus.

It’s unclear if a baggage handler with the virus poses any threat to passengers, but the National Institutes of Health said this week that the coronavirus is capable of living on surfaces for several hours.

In the memo to employees, American said it “conducted a thorough deep clean of the areas where the team member may have come into contact.”

American also was notified this week of a flight attendant who reported having COVID-19, but that individual has not worked a flight since mid-February.

“We have reached out to a flight attendant who reported falling ill with COVID-19 after attending training earlier in March," the company said in a statement. American declined to say where the flight attendant was based.

American has already been working with the FAA to reduce the number of continuing training courses required for flight attendants to reduce close contact among employees and “minimize their time in a classroom setting.” There are still a few classes going on, but with a reduced number of students, Freed said.

Last week, American Airlines said a DFW-based pilot had a confirmed case of COVID-19.
