The government’s top experts in infectious diseases on Tuesday criticised American Airlines’ decision to pack flights full while the coronavirus outbreak continues to grow across much of the United States.
“Obviously that is something that is of concern. I’m not sure what went into that decision making,” Dr Anthony Fauci told a Senate panel.
“I think in the confines of an airplane that becomes even more problematic.”
Several US airlines say they are limiting capacity on planes to between 60% and 67% of all seats.
However, United Airlines never promised to leave seats empty, and American said last week that starting on Wednesday it would drop its effort to keep half of all middle seats empty.
“When they announced that the other day obviously there was substantial disappointment with American Airlines,” said Dr Robert Redfield, director of the US Centres for Disease Control and Prevention.
“I can say this is under critical review by us at CDC. We don’t think it’s the right message.”
American Airlines spokesman Ross Feinstein said the airline has “multiple layers of protection in place for those who fly with us, including required face coverings, enhanced cleaning procedures, and a pre-flight Covid-19 symptom checklist.”
He said American was also giving customers the option of changing their ticket if their flight might be full.
The bosses of American and United have said that even with middle seats empty, it is impossible to follow 6-foot social-distancing on a plane, so airlines rely on masks, deep cleaning and air-filtration systems on planes to prevent spreading the virus.
“It’s less about social distancing and it’s more about the air and quality of air on board the airplane that makes people safe,” said United Airlines chief Scott Kirby, who added he had not seen the health officials’ comments.
Airlines are desperate to increase revenue as they try to survive a plunge in air travel that reached 95% during April.
Many airline flights were nearly empty in the early weeks of the outbreak, with the average dipping to about 10 passengers, according to industry figures.
Some days, there were fewer than 100,000 people flying in the United States, a level not seen since the 1950s, except in the days following the September 2001 terror attacks.
Air travel has increased slowly since mid-April — although it’s still down 75% from normal — and some flights have been packed.
American, which is based in Fort Worth, Texas, plans to increase flights by nearly 60% starting July 7 compared with June, which could help avoid full planes.
Delta Air Lines, Southwest Airlines, JetBlue Airways and Alaska Airlines say they will continue to limit capacity, in some cases through September. Budget carrier Spirit Airlines does not.
