Ten mainline airlines currently operate the remaining fleet of around 189 Airbus A380s. Although the Superjumbo is the largest airliner in the world, it does not operate the longest nonstop flights. These are managed by other aircraft like the Airbus A350-900ULRs and Boeing 787-9 Dreamliners. However, the A380 does conduct ultra-long flights, including one-stop routes.
A new airline named Global Airlines plans to begin transatlantic flights soon using ex-China Southern A380s. However, these do not appear in Cirium's data for 2025 and are unlikely to be among the longest A380 routes as they will likely fly from the UK to New York-JFK.
"Emirates operates a fleet of 116 A380s (six of which have been parked since 2020), British Airways and Singapore operate 12, Qantas operates ten, Lufthansa and Qatar Airways operate eight, Etihad and Korean Air operate seven, Asiana operates six, and ANA has three."
