American said Monday that it flew a Boeing 777 between its hubs at Chicago O’Hare International Airport and Miami and that the vaccines would later land in a “U.S. territory in the Caribbean later today.” A spokeswoman for the carrier declined to disclose the destination.
American operated stress test flights last month to make sure its network and supply chain could handle temperature and other requirements to ship coronavirus vaccines. The Food and Drug Administration on Friday approved Pfizer and BioNTech’s Covid-19 vaccine for emergency use.
United last month started flying a series of flights to transport vaccines on its largest aircraft between Brussels and its Chicago hub. Passenger airlines are working alongside shipping giants like FedEx and United Parcel Service in distributing the vaccines.
