Delta CEO expects COVID immunity proof for international flight but won't call it 'vaccine passport'

Delta Air Lines CEO Ed Bastian anticipates some proof of immunity to the coronavirus will be required to travel internationally but said the company will rely on regulators around the world to determine what is required and won't be using term "vaccine passport."

"We don't call it a vaccine passport. It carries too many connotations. We're more focused on travel credential if you will, to indicate that you've been vaccinated and/or tested based on the regulatory requirements," Bastian on Tuesday told Yahoo Finance. 

He also said Delta in the first quarter of this year had more-than-expected losses but that company expecting to reach profitability in the near future – as tech groups create easy ways for passenger to show vaccination credentials at airports.

"We're working with a number of technology providers to be able to facilitate that in an open source way so that it's easy for customers to pull up their vaccination credentials and streamline their travel."
