Singapore Airlines is a major global operator. According to ch-aviation, the carrier has 149 passenger aircraft. Its fleet consists of 65 Airbus A350-900s, 28 Boeing 787-10s, 22 737 MAX 8s, 22 777-300ERs, and 12 A380s. 85% of its aircraft are widebodies. Historically, regional unit Silk Air deployed narrowbodies on its behalf.

In 2026, OAG data shows that Singapore Airlines is the world’s 17th-largest international carrier by available capacity. This is influenced by its scale and having no domestic market. If long-haul services are considered, it ranks 11th.

Singapore Airlines’ Two Longest Nonstop Flights

Unlike some articles, which combine one-stop and nonstop services, this article focuses exclusively on nonstop activity. As usual, the maximum block time is considered instead of the great circle distance. Reflecting slot possession, this is measured as chocks-off-to-chocks-on, or gate-to-gate or stand-to-stand. It includes taxi time at both ends of a route, flight time, a short period for delays.

Singapore Airlines’ schedule submission to OAG for May to December has been explored. This indicates that New York JFK back to Changi is the carrier’s longest nonstop scheduled service. It is also the world’s longest link, at least until Qantas’ nonstop flights from Sydney to London begin.

Running daily on the 161-seat A350-900ULR, with only business and premium economy seats, Singapore’s offering is timed at up to 19 hours and 15 minutes. It exceeds the maximum block time of the second-longest link, Newark back to the city-state, by five minutes (daily A350-900ULR).

These two routes should not be surprising. They are always first and second. Flightradar24 shows that they fly over the Pacific to the US, and over Europe on the way back to Asia. They have done this for a long time. The carrier benefits from tailwinds, which reduces fuel consumption, emissions, journey time, and overall operating expenses.

Singapore’s Third To Fifth-Longest Nonstop Flights

Unsurprisingly, flights from Singapore to JFK/Newark are so long as to be longer than the third distinctive route. As they’re simply a different leg of the same markets, they are not considered separately. As such, Singapore Airlines’ third-longest nonstop offering is Los Angeles back to Singapore. Timed at up to 17 hours and 50 minutes, the carrier runs 10 weekly on both the A350-900 and, from November, also on the A350-900ULR. Its one-stop flights via Tokyo are excluded.

San Francisco back to Changi is fourth. At up to 17 hours and 30 minutes, the carrier operates twice-daily on the A350-900 and, until October, also on the A350-900ULR. In fifth place is Seattle back to the city-state (five weekly A350-900), with the block time being a maximum of 17 hours.

Part of Singapore Airlines’ network since 2019, Seattle flights operate nonstop in both directions. They were tagged with Vancouver during the pandemic, although British Columbia no longer sees the carrier’s passenger frames. According to the US Department of Transportation, Singapore Airlines filled 91.6% of its Seattle seats in the 12 months to January 2026. This was its best-performing US route in this sense (as always, it should not be considered in isolation).

The Sixth To Tenth-Longest Nonstop Flights

Things open up considerably in this category. Not just in terms of routes, but also equipment. Two links are tied for the sixth spot. At up to 14 hours and 30 minutes, there’s Singapore to both London Heathrow (four daily A350-900, A380, 777-300ER; the A350 appears in July) and London Gatwick (daily to two daily A350-900; the highest frequency exists during the peak northern summer).

In seventh place is Singapore to Manchester (up to 14 hours and 25 minutes; five weekly A350-900). Then there’s Changi to Paris CDG (up to 14 hours and 15 minutes; 10 weekly to twice-daily A350-900/777-300ER) and Singapore to Barcelona (up to 14 hours and five minutes; two to five weekly nonstop A350-900; other flights operate via Milan). Finally, in tenth place, is Changi to Brussels (up to 13 hours and 55 minutes; four weekly A350-900), which welcomed the airline in 2024. As usual, other routes were extremely close to being included.
