Which airlines fly out of Heathrow Terminal 3?

Terminal 3 is used by the majority of the members of the Oneworld airline alliance: American Airlines, Cathay Pacific, Finnair, Iberia, Japan Airlines, Qantas, Royal Jordanian, and SriLankan Airlines. British Airways, which mainly uses Terminal 5, also offers some flights from this terminal.



London Heathrow Terminal 3 is primarily the home of the oneworld alliance (excluding British Airways, which is mostly in T5) and several other major international long-haul carriers. As of 2026, the "anchor" airlines in Terminal 3 include Virgin Atlantic, American Airlines, Delta Air Lines, and Emirates. Other key oneworld members operating here are Cathay Pacific, Qantas, Japan Airlines (JAL), Finnair, and SriLankan Airlines. You will also find several independent and Star Alliance carriers such as LATAM, Vistara, and Royal Jordanian. Terminal 3 is particularly famous among travelers for its world-class lounge scene, featuring the award-winning Virgin Atlantic Clubhouse and the Cathay Pacific First and Business lounges. It is important to note that while Delta and Virgin Atlantic are partners, they operate exclusively out of Terminal 3 to maximize their "co-location" benefits. Always double-check your terminal on the "Heathrow" app before you arrive, as airlines occasionally shift operations due to seasonal capacity changes or terminal maintenance projects.
