For many travellers, a flight is simply a way of getting from A to B. But some routes are destinations in themselves. Stretching across oceans, continents and multiple time zones, the world's longest flights represent the pinnacle of modern aviation, connecting cities that once required several stopovers and well over a day of travel.
Today, ultra long-haul aircraft allow passengers to fly non-stop for nearly 19 hours, making it possible to travel between some of the most distant city pairs on the planet without changing planes. Whether you're planning a once-in-a-lifetime trip or simply fascinated by aviation, here are some of the longest flight routes currently operating around the world.
What Is the Longest Non-Stop Flight in the World?
The title currently belongs to Singapore Airlines' service between Singapore and New York (JFK).
- Distance: Approximately 9,537 miles (15,349 km)
- Flight time: Up to 19 hours
- Typical Aircraft: Airbus A350-900ULR
This remarkable route connects Southeast Asia with the US East Coast and is specifically operated using an ultra long-range version of the Airbus A350, designed to maximise efficiency on marathon journeys.
If you're planning a trip to New York, you can compare flights to the city and explore accommodation options before you travel:

Singapore to Newark
Another Singapore Airlines service ranks among the longest routes in the world.
- Distance: Approximately 9,520 miles
- Flight time: Around 18 hours 45 minutes
- Typical Aircraft: Airbus A350-900ULR
Although Newark and JFK both serve New York City, the routes operate separately and consistently appear at the very top of the world's longest-flight rankings.
Perth to London
When Qantas launched its non-stop service between Perth and London, it transformed travel between Australia and Europe.
- Distance: Approximately 9,009 miles
- Flight time: Around 17 hours
- Typical Aircraft: Boeing 787 Dreamliner
Previously, travellers flying from Australia to the UK needed at least one stop in Asia or the Middle East. Today, passengers can fly directly between Western Australia and London.

Dallas Fort Worth to Melbourne
Australia features heavily in the ultra long-haul market due to its geographic location.
The route between Dallas Fort Worth and Melbourne covers an immense distance across the Pacific Ocean.
- Distance: Approximately 8,992 miles
- Flight time: Around 17 hours
- Typical Aircraft: Boeing 787 Dreamliner
This service provides a vital link between Australia and the southern United States without requiring passengers to transit through Los Angeles.
Auckland to New York
Air New Zealand's Auckland to New York route marked a significant milestone for the airline when it launched.
- Distance: Approximately 8,828 miles
- Flight time: Up to 17.5 hours
- Typical Aircraft: Boeing 787 Dreamliner
The route dramatically reduces travel times between New Zealand and the United States East Coast.

Doha to Auckland
Qatar Airways has long been a leader in ultra long-haul travel.
Its service between Doha and Auckland remains one of the longest routes anywhere in the world.
- Distance: Approximately 9,032 miles
- Flight time: Around 17 hours 30 minutes
- Typical Aircraft: Boeing 777
The flight spans multiple continents and crosses vast stretches of ocean, making it one of aviation's most impressive achievements.
Why Are Long-Haul Flights Becoming More Popular?
Several factors have driven the growth of ultra long-haul routes:
More Efficient Aircraft
Modern aircraft such as the Airbus A350, and Boeing 787 Dreamliner consume significantly less fuel than older aircraft, making previously impossible routes commercially viable.
Passenger Convenience
Many travellers prefer a single long flight over multiple connections. Avoiding airport transfers, immigration queues and missed connections can make a journey far less stressful.
Growing Global Demand
Business and leisure travel continue to connect increasingly distant cities. Airlines are responding by introducing direct flights between major economic and tourism hubs.
The Challenges of Flying for 18+ Hours
While non-stop flights save time overall, they present unique challenges.
Jet Lag
Crossing numerous time zones can disrupt sleep patterns for several days after arrival.
Cabin Fatigue
Even on modern aircraft, spending almost an entire day in the air can be physically demanding.
Travellers on long-haul flights should:
- Stay hydrated
- Walk around the cabin regularly
- Avoid excessive alcohol consumption
- Adjust sleep schedules before departure where possible
Crew Logistics
Ultra long-haul flights require multiple flight crews, dedicated crew rest areas and carefully planned fuel management systems.
Could Flights Get Even Longer?
The answer is yes.
Qantas has been developing its "Project Sunrise" initiative, which aims to operate non-stop flights from Sydney to destinations such as London and New York.
Once fully implemented, these services could exceed 19 hours in the air and challenge the current record holders for the world's longest commercial flights.
Such routes would allow travellers to fly directly between Australia and Europe or the United States without intermediate stops, which would have seemed impossible only a generation ago.
What About the Shortest Flights in the World?
While some aircraft spend almost an entire day in the air crossing oceans and continents, others complete their journeys in a matter of minutes. The contrast is remarkable. Ultra-short routes play an important role in connecting remote communities and offer a fascinating glimpse into the other end of commercial aviation.
