In recent years, air travel has seen remarkable advancements, with ultra-long-haul flights redefining our perception of distance and connectivity. These marathon journeys, spanning thousands of kilometers non stop, have become emblematic of modern aviation’s capabilities. They not only bridge continents but also minimize travel time, offering passengers unparalleled convenience and efficiency.
In this article, we will delve into the top 10 longest non stop flights as of 2025, examining each route’s specifics and the unique experiences they offer to travelers.
The Top 10 Longest Non Stop Flights in 2025
1. Singapore (SIN) to New York (JFK) – Singapore Airlines SQ23
Singapore Airlines runs Flight SQ23 from Singapore Changi Airport (SIN) to New York’s John F. Kennedy International Airport (JFK), covering about 15,349 kilometers (9,537 miles) in around 18 hours and 50 minutes. The service uses the Airbus A350-900ULR, designed specifically for ultra-long-haul flights with better fuel efficiency and passenger comfort.
The Airbus A350-900ULR used for this route is configured to prioritize passenger comfort on long-duration flights. The aircraft features a spacious cabin layout, advanced air quality systems, and reduced noise levels, all contributing to a more comfortable travel experience.
Ticket prices for SQ23 vary based on cabin class and booking time. As of 2025, round-trip fares from New York to Singapore start at approximately USD 1,076 for Economy Class and can exceed USD 4,600 for Business Class, depending on the season and availability.
Due to the extended duration of SQ23, certain operational considerations are in place. For instance, Singapore Airlines does not permit the carriage of pets on this non stop flight, ensuring the well-being of animals during such a lengthy journey.
2. Newark (EWR) to Singapore (SIN) – Singapore Airlines SQ21
Singapore Airlines’ Flight SQ21 connects Newark Liberty International Airport (EWR) to Singapore Changi Airport (SIN), covering a distance of 15,344 kilometers (9,534 miles) in approximately 18 hours and 45 minutes. This route is operated using the Airbus A350-900ULR.
To enhance passenger comfort, Singapore Airlines has configured the A350-900ULR without an economy class section. Instead, the aircraft offers 67 business class seats and 94 premium economy seats. This strategic choice addresses both passenger comfort and operational efficiency, as it reduces the aircraft’s weight, thereby optimizing fuel consumption over such a long distance.
Passengers on Flight SQ21 get a solid mix of comfort and service. Business class seats give you plenty of space and convert into fully flat beds, making it easier to get real sleep mid-flight. Premium economy offers more legroom and a deeper recline compared to regular economy, giving you extra comfort without the full business class price. The KrisFlyer entertainment system is packed with movies, music, and games to help pass the time.
Singapore Airlines first launched non stop flights between Newark and Singapore in 2004 with the Airbus A340-500. Rising fuel costs and other challenges forced a suspension in 2013. In 2018, the airline brought the route back using the more fuel-efficient A350-900ULR, showing just how strong the demand is for direct flights between these two major financial centers.
