Airlines will need to meet a “harmonized” standard of health measures as air travel returns following the global pandemic, according to the CEO of Etihad Airways.

“I can see that wellness certification will become a necessary function of how the whole of the world comes back to flying,” Tony Douglas told CNBC’s Hadley Gamble last week as part of the Global Aerospace Summit.

For Etihad, a United Arab Emirates flag carrier, efforts to ensure “wellness” include sterilization of cabins, mandatory coronavirus tests for passengers and tracking wristbands to be worn during the compulsory 14-day quarantine.
