Top 10 Longest Flights Worldwide in 2024

As flight technology continues to advance, airlines are stretching the limits of long-haul travel, offering passengers ultra-long-haul routes that connect distant cities with flights lasting up to 20 hours. Thanks to improvements in fuel efficiency, passenger comfort, and inflight amenities, these lengthy journeys are becoming more manageable and even attractive to travelers who value direct flights. The longest flights now span over 17 hours, providing direct links between major global hubs, from New York to Singapore and Sydney to London.

1. Upcoming Project Sunrise by Qantas

Set to launch in 2026, Qantas’ Project Sunrise aims to redefine long-haul travel by introducing nonstop flights from Sydney to London and Sydney to New York. The Sydney-London route will cover approximately 10,573 miles, making it the longest commercial flight in the world, expected to take around 20 hours. The aptly named Project Sunrise promises passengers unique experiences, including viewing two sunrises during the journey.

Qantas is designing this flight with a focus on passenger well-being, offering enhanced lighting to reduce jet lag, nutrient-rich meals, and innovations in cabin comfort for both business and economy passengers. Once operational, these flights will claim the title of the longest commercial routes globally.

2. Current Longest Flight: Singapore Airlines from New York to Singapore

Currently, the world’s longest nonstop flight is operated by Singapore Airlines between New York (JFK) and Singapore, covering approximately 9,585 miles and lasting up to 18 hours and 50 minutes. This route is serviced by the Airbus A350-900ULR, which is specifically configured to enhance passenger comfort on such long journeys. With 67 pod-style business-class seats and 94 premium economy seats, passengers can rest comfortably, although standard economy seats are notably absent.

3. Emirates’ Nonstop from Dubai to Auckland

Emirates operates another ultra-long-haul route from Dubai to Auckland, New Zealand, which spans 8,824 miles and lasts around 17 hours and 20 minutes. This flight connects the Middle East to Oceania, allowing travelers to reach New Zealand directly without layovers. Passengers on this route benefit from Emirates’ renowned inflight service, which includes premium food, entertainment, and a range of seating options to suit both business and leisure travelers.

4. Qantas from Dallas to Sydney

Among the top 15 longest flights globally, Qantas operates a nonstop route between Dallas and Sydney, which lasts around 16 hours and 21 minutes. This route offers a unique experience for travelers, with attentive service, comfortable seating, and the airline’s well-regarded hospitality. Qantas has invested in passenger comfort for long-haul flights, ensuring that business-class travelers can sleep comfortably in fully flat beds.

Experience of Ultra-Long-Haul Flights

Flying on one of these extended routes is a unique experience. In premium cabins, travelers enjoy enhanced sleep setups, including lie-flat seats, mattress toppers, and even complimentary pajamas on some airlines. Business travelers often appreciate these amenities, as they can arrive at their destination feeling refreshed and ready for their next engagement.

However, even in premium economy, the experience varies. For instance, the aisle seats can be less comfortable for sleeping due to frequent passenger movement. Passengers who prioritize comfort may find it worth investing in business class on these ultra-long-haul flights, especially given the hours spent in transit.

Choosing the Right Long-Haul Journey

For those who enjoy getting the entire journey over in one go, these ultra-long-haul flights can be ideal. On the other hand, some travelers may prefer breaking up the trip with a stopover to experience an additional city en route to their final destination. Many airlines offer stopover programs, allowing passengers to explore a new city while reducing the strain of a single lengthy flight.

In the age of advanced aviation technology, the world is more connected than ever. With routes spanning up to 20 hours, travelers can now fly farther and faster, reaching distant corners of the globe with ease and enhanced comfort. Whether you prefer nonstop journeys or breaks for sightseeing, today’s longest flights cater to diverse travel styles, allowing passengers to arrive at their destinations refreshed and ready for adventure.
