In the week since international travelers were welcomed back to the United States, airlines, nonprofit organizations and travel groups have finally seen an uptick in the digital health passes they had hoped travelers would use since their launch.

American Airlines has been seeing a nearly 10 percent increase in its VeriFLY app usage for travel since the Nov. 8 lifting of U.S. entry restrictions, said spokeswoman Rachel Warner. Tech research firm Apptopia noticed a 5 percent increase in downloads of these kinds of apps from the week before the travel ban was lifted, according to Thomas Grant, the company’s director of equity research.

Travel industry experts credited this rise to the new flood of international travelers.
