Plane Facts: The world's longest flights

Ultra-long-haul flights push the boundaries of aviation, connecting distant continents in single journeys that can last almost a full day. These routes represent remarkable feats of engineering and endurance for both aircraft and passengers.

What is currently the world's longest flight?

New York (JFK Airport) to SIngapore (Changi Airport) with Singapore Airlines

Singapore Airlines operates the world's longest commercial flight, connecting New York's JFK Airport to Singapore Changi Airport. This epic journey covers 15,332 kilometres (9,527 miles) and takes approximately 18 hours and 40 minutes eastbound, with return flights lasting up to 19 hours due to prevailing winds.

The route launched in 2018 using the Airbus A350-900ULR (Ultra Long Range), specifically configured for extended flights with additional fuel capacity. Singapore Airlines offers only business and premium economy classes on this route, prioritising passenger comfort and even weight distribution over maximum capacity.

How do airlines manage ultra-long-haul flights?

Airlines deploy their most advanced aircraft for these routes. The Airbus A350-900ULR and Boeing 787 Dreamliner feature enhanced fuel efficiency, improved cabin pressurisation, and better humidity control to reduce passenger fatigue.

Crew management becomes complex on flights exceeding 16 hours. Airlines typically carry additional pilots and cabin crew, with dedicated rest areas allowing teams to rotate during flight. Some routes require technical stops for crew changes while passengers remain aboard.

What are your rights on the longest flights?

Ultra-long-haul flights fall under the EU261 regulation when departing from European airports or operated by EU/UK carriers. This means passengers can claim up to €600 compensation for significant delays or cancellations.

However, extraordinary circumstances like severe weather or air traffic control strikes remain exempt from compensation requirements, even on ultra-long routes.

Are longer flights more likely to be delayed?

Ultra-long-haul flights face unique challenges that can increase delay risks. Extended flight times mean greater exposure to weather systems, air traffic congestion, and technical issues. Additionally, these routes often operate with minimal schedule padding, making recovery from initial delays difficult.

However, airlines typically prioritise their flagship long-haul services with premium aircraft maintenance and experienced crews, potentially offsetting some delay risks. Route planning also accounts for seasonal weather patterns and air traffic flows.
