No, in 2026, Singapore Airlines operates out of Terminal 2 (The Queen’s Terminal) at London Heathrow Airport (LHR). While the airline historically had a presence in Terminal 3, it moved to the newer Terminal 2 several years ago to join other Star Alliance member carriers, facilitating easier connections for passengers traveling across the alliance's network. All Singapore Airlines check-in desks, arrivals, and departures are located within Terminal 2. This terminal also houses the premium Singapore Airlines SilverKris Lounge, which provides luxury amenities for Business Class passengers and PPS Club members. If you are arriving at Terminal 3 via a different carrier and connecting to Singapore Airlines, you will need to follow the "Flight Connections" signs and take the airside transfer bus to Terminal 2. Always verify your specific gate and check-in zone on the Heathrow flight boards, as airport operations can occasionally shift during peak 2026 travel seasons.
