Imagine boarding a flight in New York and landing in Singapore more than 19 hours later, without stopping anywhere along the way. That’s what passengers can expect on the world’s longest scheduled nonstop passenger flight. Today, airlines connect distant cities with flights that can last almost an entire day. Let’s look at the 10 longest nonstop flights in the world in 2026.

Which Is the Longest Nonstop Flight in the World?

The longest scheduled nonstop passenger flight in 2026 is from New York’s John F. Kennedy International Airport (JFK) to Singapore Changi Airport (SIN). Singapore Airlines operates this route, which covers about 9,532 miles. The scheduled block time is 19 hours and 15 minutes.

The airline also operates the second-longest flight, from Newark Liberty International Airport (EWR) to Singapore. That trip has a scheduled block time of 19 hours and 10 minutes, just five minutes less than the JFK service.

Both routes use the Airbus A350-900ULR, an ultra-long-range version of the A350-900 designed for extended nonstop journeys. For passengers traveling between the United States and Singapore, these services remove the need to change planes along the way.

Top 10 Longest Nonstop Flights in the World in 2026

Here are the 10 longest nonstop flights ranked by their longer scheduled block time in either direction. The ranking is based on September 2026 schedule data and includes seasonal services. Some routes may not operate nonstop in both directions or throughout the year.

Why Does Singapore Airlines Have the Longest Nonstop Flights?

Singapore is a long way from New York, but Singapore Airlines offers travelers a way to fly between the two cities without stopping. Its JFK and Newark services are the only two flights on this list with scheduled block times exceeding 19 hours.

For travelers, the main benefit is convenience. Instead of waiting at another airport and boarding a second plane, they can stay on the same flight until they reach Singapore. Of course, sitting on a plane for more than 19 hours isn’t easy for everyone. But some passengers may prefer one long flight over a journey with a connection.

Why Are Australian Routes Among the Longest Flights?

Australia is far from many major cities in Europe and North America. That’s why several routes connecting Australia with Europe and North America appear in the top 10.

The London Heathrow to Perth route is listed at 17 hours and 50 minutes. Qantas operates this nonstop service. However, the Perth-to-London direction was not operating nonstop in the September and December 2026 schedules checked by Passrider. Travelers should check the airline’s current schedule before booking.

Another Qantas route, Dallas/Fort Worth to Melbourne, has a scheduled block time of 17 hours and 40 minutes. United Airlines also operates a long flight between Houston and Sydney, with a scheduled block time of 17 hours and 35 minutes. This is a seasonal service.

Qantas also operates the seasonal Perth-to-Paris route, which has a scheduled duration of 17 hours and 30 minutes in the ranking. These routes can give passengers a way to travel between distant cities without stopping at another airport.

Why Do Some Shorter Flights Take Longer?

You might expect the flight covering the most miles to take the most time. But that isn’t always how it works. Wind plays a big part in how long a flight takes. Strong tailwinds can help an aircraft reach its destination sooner. Headwinds can slow the aircraft down.

The direction of travel also matters. A flight going one way may take longer than the return trip. Airlines also plan their schedules around weather, flight paths and other operating needs. That’s why two routes covering different distances can have similar scheduled flight times.

What Should Travelers Know Before Booking a Long Nonstop Flight?

A flight lasting 17 to 19 hours needs a little more planning than a short trip. Before booking, check the total travel time and compare it with flights that include a stop. A nonstop ticket may save time, but a connecting flight could give you a break along the way.

Seat choice also matters when you’ll be sitting for so many hours. If possible, choose a seat that feels comfortable for a long journey. Keep your medicines, travel documents, phone charger and other important items in your carry-on bag. During the flight, drink water and get up to stretch when it’s safe to do so. Small things like these can make a long journey more comfortable.

The World’s Longest Nonstop Flights in 2026

The world’s longest nonstop flights show just how far air travel has come. Singapore Airlines leads the list with its New York JFK to Singapore service, which has a scheduled block time of 19 hours and 15 minutes. Other airlines, including Qantas and United Airlines, also operate some of the world’s longest nonstop routes.

For travelers, these international flights offer a way to reach distant cities without changing planes. Before booking, compare scheduled travel times, ticket prices and comfort options to choose a journey that works best.
