Singapore Airlines has 22 passenger Boeing 777-300ERs. Averaging 16.2 years, they only constitute 15% of the airline’s passenger fleet. The carrier’s oldest remaining triple seven is 9V-SWB, which was delivered in late 2006.

All of Singapore Airlines’ 777-300ERs are configured in a reasonably premium way. There are just 264 seats, featuring four seats in first (1-2-1), 48 in business (1-2-1), 28 in premium economy (2-4-2; 38″ pitch), and 184 in regular economy (3-3-3; 32″). It is the carrier’s only twinjet equipment to have first class.

The Star Alliance member’s full 777-300ER network between July and December 2026 has been explored using OAG data. While only nonstop flights are sometimes examined, that’s not the case here. The variant’s nonstop and one-stop routes have been identified based on the maximum block time. This includes taxiing at both ends of the route, the flight time, and a short delay period.

Timed at up to 24 hours and 20 minutes, Singapore Airlines’ longest 777 passenger service is from Singapore Changi Airport (SIN) to John F. Kennedy International Airport (JFK) via Frankfurt Airport (FRA). Flown daily, fifth-freedom traffic rights are available between FRA and JFK. As everyone knows, Singapore Airlines operates the A350-900 ULR nonstop between SIN and JFK.

The US Department of Transportation (DOT) records show that Singapore Airlines has operated flights between FRA and JFK since 1992. More than 5.5 million passengers have been transported. The 747-400 was used for years, followed by the A380. The Airbus A350-900 briefly appeared during the COVID-19 pandemic. The 777-300ER replaced the A380 in 2023.

At up to 20 hours and 35 minutes, Los Angeles International Airport (LAX) back to SIN via Tokyo Narita Airport (NRT) ranks second. The one-stop operation has existed for decades. The 264-seater still operates daily, with fifth-freedom rights available. The A380 and 747-400 flew before.

There’s a significant gap between the second and third entries because nonstop services take over. The third-longest 777-300ER operation is from SIN to London Heathrow Airport (LHR), which is timed up to 14 hours and 25 minutes (daily on the variant). Then there’s SIN to Paris Charles De Gaulle Airport (CDG; up to 14 hours and 15 minutes; daily 777) and SIN to Amsterdam (up to 13 hours 50 minutes; daily 777).

Timed up to 13 hours and 45 minutes on the 777-300ER, SIN to FRA is in sixth place. It is the first leg of the SIN-FRA-JFK routing. Then there’s SIN to Zurich Airport (ZRH; up to 13 hours and 30 minutes; daily on the variant), SIN to Auckland Airport (AKL; up to 10 hours and 50 minutes; daily 777), Sydney back to SIN (up to 8 hours and 25 minutes; daily 777), and Melbourne back to SIN (up to eight hours; daily 777). Singapore Airlines previously flew the A380 to the premium-heavy ZRH, while that type returns to AKL later this year.

In 11th place is SIN to Dubai (up to seven hours and 45 minutes). Due to the ongoing war in Iran, flights to the United Arab Emirates’ busiest airport have been suspended. While subject to change, they are due to resume on August 3. When they do, the 777-300ER will operate daily. Earlier this year, the A380 was due to replace the triple seven, but that won’t happen now.
