Traveling halfway around the world no longer requires a connecting flight. Some of today’s longest commercial routes keep passengers on board for more than 19 hours, pushing the limits of nonstop air travel.
This visualization ranks the world’s 10 longest nonstop flights by scheduled duration, revealing which cities are connected by these marathon journeys.
The data comes from Passrider.com, with route durations compiled as of September 2026, including seasonal routes. Flights are ranked by their longer scheduled direction, with distance used as a tiebreaker.
Singapore Airlines Operates the Two Longest Nonstop Flights
Singapore Airlines dominates the top of the ranking, operating the only two routes scheduled to exceed 19 hours.
Both connect Singapore Changi Airport with the New York metropolitan area, departing from JFK and Newark, respectively. The JFK route covers 9,532 miles, making it one of the most demanding nonstop journeys in commercial aviation.
The following table ranks the longest nonstop flights by duration:
| Rank | Departing | Arriving | Duration (HH:MM) |
Distance (Miles) |
|---|---|---|---|---|
| 1 | New York JFK | Singapore SIN | 19:15 | 9,532 |
| 2 | Newark EWR | Singapore SIN | 19:10 | 9,530 |
| 3 | Perth PER | London LHR | 17:50 | 9,015 |
| 4 | New York JFK | Auckland AKL | 17:50 | 8,833 |
| 5 | Dallas DFW | Melbourne MEL | 17:40 | 8,995 |
| 6 | Houston IAH | Sydney SYD | 17:35 | 8,597 |
| 7 | Perth PER | Paris CDG | 17:30 | 8,869 |
| 8 | Dallas DFW | Hong Kong HKG | 17:15 | 8,111 |
| 9 | Los Angeles LAX | Singapore SIN | 17:10 | 8,762 |
| 10 | Auckland AKL | Dubai DXB | 17:05 | 8,824 |
Just five minutes separate the top two routes, which cover nearly identical distances.
Both use the Airbus A350-900ULR, an aircraft specifically designed for ultra-long-haul travel. Their scheduled durations are also at least 85 minutes longer than any other flight in the top 10.
Australia Dominates the Next Tier of Long-Haul Flights
Australian routes feature prominently among the world’s longest nonstop flights, with Qantas, one of the world’s top airlines by revenue, operating several of the highest-ranked services.
Perth to London Heathrow ranks third at 17 hours and 50 minutes, covering 9,015 miles.
The New York-JFK to Auckland route, operated by Qantas and Air New Zealand, matches that duration despite covering a shorter distance of 8,833 miles.
Qantas also operates the fifth-longest route, from Dallas/Fort Worth to Melbourne, at 17 hours and 40 minutes, while United Airlines’ Houston to Sydney service ranks sixth at 17 hours and 35 minutes.
How Flight Duration Differs From Distance
Flying farther doesn’t always mean spending more time in the air.
Scheduled flight times are influenced by prevailing winds, flight direction, and operational planning. As a result, a shorter route can sometimes take longer than a more distant one.
For example, Shenzhen to Mexico City spans 8,780 miles but is scheduled for 16 hours and 15 minutes. Dallas/Fort Worth to Hong Kong covers just 8,111 miles yet takes an hour longer.
Other major long-haul connections include Auckland to Dubai and Dubai to Los Angeles, both operated by Emirates and scheduled at 17 hours and five minutes, despite the former being nearly 500 miles longer than the latter.
These ultra-long-haul services represent a different side of global aviation from the world’s busiest flight routes by region, where passenger demand and frequency are key measures of activity.
Together, these routes demonstrate how modern commercial aircraft can connect distant cities without a single stop.
