Top airline and business groups are asking the Biden administration to take a leading role in developing standards for credentials that would let travelers show they have been tested and vaccinated for COVID-19. Airlines hope such a document would allow countries to relax travel restrictions aimed at curbing the spread of the virus. More than two dozen airline and business groups including the U.S. Chamber of Commerce wrote to the White House about the matter on Monday. Despite backing a travel credential, the groups oppose requiring vaccinations for domestic or international travel.
