Denver International Airport is one of the busiest airports in the United States, and it offers a huge number of flights to destinations across North America and around the world. No US-based carriers purchased the Airbus A380 Superjumbo, and so all A380s seen at American airports are operated by international carriers. Currently, Denver only attracts A380s operated by Germany’s flag carrier, Lufthansa, but it is also hoping to entice Emirates and its A380s.
