Emirates, Etihad Airlines to test IATA COVID-19 travel pass
Emirates Airlines and Etihad Airways said they have partnered with the International Air Transport Association to trial IATA Travel Pass -- a mobile app that serves as a “digital passport” to verify pre-travel COVID-19 testing or vaccination status.
The app also helps passengers find information on travel and entry requirements at their destinations.
Emirates Airlines said it plans to roll out the first phase in April, during which passengers leaving Dubai can share their COVID-19 test status directly with the airline through the app before arriving at the airport. Etihad will first offer the travel pass on some flights out of Abu Dhabi in the first quarter of 2021.

The U.S. death toll surpassed 400,000 on Tuesday and now stands at 400,022 fatalities.
The number of American lives lost to the coronavirus is more people than the number of U.S. soldiers who died in battle during World War I, World War II and the Vietnam War combined, according to a data estimate compiled by the Department of Veterans Affairs.
The U.S. death toll is roughly equivalent to the population of Tampa, Florida, or Tulsa, Oklahoma.
By the middle of February, "we expect half a million deaths" in the U.S. from COVID-19, Dr. Rochelle Walensky, who’s nominated to serve as the next director of the Centers for Disease Control and Prevention, told CBS’ "Face the Nation" on Sunday.

Herd immunity by fall an ‘ambitious goal,’ says nominee for surgeon general
The possibility of obtaining herd immunity by the time summer is over and a new school year begins may be an "ambitious goal," Vivek Murthy, President Joe Biden's nominee for U.S. surgeon general, told George Stephanopoulos on "This Week" Sunday.
"I think what -- I think we can see improvement," Murthy said. "I think we can see reductions in cases and hospitalizations and deaths. I think we can see many more people immunized."
The "important thing" will be getting as many people vaccinated as possible, Murthy added.
"The more people we vaccinate, the better we will do, the fewer outbreaks we will see, the sooner we can get back to our way of life," he said.
Murthy also emphasized the importance of dispelling misinformation as well as continuing to take the necessary precautions, such as wearing masks and avoiding indoor gatherings.
"Then I think we can be on a path to not only turning the pandemic around, but, most importantly, getting our schools open, our workplaces back up and running, and regaining our way of life," he said.
