Glimmers of a gradual return to air travel mean airlines are rolling out new policies aimed at protecting passengers and crew from coronavirus transmission and increasing consumer confidence in air travel safety.
One day after the TSA marked its highest number of screened passengers in the US since April 3, JetBlue Airways announced that it will require all passengers to wear face masks starting on May 4. Crew members were already required to wear masks.
The TSA figure -- 128,875 passengers screened on Sunday -- was still only about 5% of the 2.5 million people screened on the equivalent day in 2019, but it's an uptick nonetheless and safety measures are top-of-mind for anyone considering flying.
JetBlue's move follows American Airlines' announcement on Monday that flight attendants will be required to wear masks beginning on May 1.
American will also start handing out sanitizing wipes and gels and face masks to customers in early May, "as supplies and operational conditions allow," the news release said.
As people in many corners of the world begin to move around more freely, airlines are issuing policies that are likely to evolve with the pandemic.
All of the carriers have plans for enhanced cleaning and sanitation.
Here's where some major carriers stand so far on personal protective equipment and social distancing measures:
All United Airlines flight attendants are required to wear face masks. United was the first major US carrier to announce the requirement.
The carrier has also modified in-flight service to minimize touchpoints and has moved primarily to pre-packaged foods and sealed beverages.
United is also implementing changes to boarding and seat assignments to promote social distancing through at least May 31.
Delta Air Lines
Delta Air Lines is requiring all employees to wear masks or face coverings when unable to maintain the six-foot social distancing rule, the airline said in a memo to employees on Monday.
"We are strongly encouraging our customers to wear masks and will make them available at ticket counters, gates and onboard airplanes," the memo also said.
Delta is blocking middle seats and reducing the number of passengers on each flight, boarding customers 10 at a time and changing food and beverage service to reduce touchpoints between passengers and crew, according to measures outlined on the carrier's website.
In addition to handing out masks to passengers and requiring flight attendants to wear them starting in May, American Airlines has turned off some computers and kiosks at ticket counters to her encourage social distancing.
Signage at gates reminds passengers not to crowd together during the boarding process. American has also reduced food and beverage service through April 30 and has limited the number of passengers on each aircraft through May 31.
"American will not assign 50% of main cabin middle seats or seats near flight attendant jump seats on every flight, and will only use those middle seats when necessary," the carrier's temporary policy reads.
JetBlue is the first major US carrier to require that passengers wear masks, effective May 4.
"Wearing a face covering isn't about protecting yourself, it's about protecting those around you," said Joanna Geraghty, president and chief operating officer of JetBlue, in a statement. "This is the new flying etiquette."
JetBlue has also limited the number of available seats on most flights and regularly reviews seat assignments to maximize space between passengers.
The carrier has adjusted food and beverage service to minimize touchpoints, with more limited offerings in many fare classes.
All Air Canada passengers are required to comply with a Canadian government mandate that all passengers flying through, to or from Canada wear a non-medical face mask or face covering over their nose and mouth.
Air Canada has adjusted its boarding procedures and is reseating customers to enable social distancing. Where adequate spacing isn't possible, passengers can choose to take a later flight at no additional cost.
Services and amenities have also been adjusted to mitigate the risk of viral transmission. Some food service has been suspended or shifted to pre-packaged fare and bar service and pillows and blankets are no longer available on some flights.
Masks and other protective equipment common are common in Asia. Since April 23, Malaysia Airlines has required all passengers (excluding infants) to wear face masks. Korean Air is providing cabin crew with protective clothing, including goggles, masks and gloves.
