Have you ever dreamed of boarding the world’s longest commercial flight, bridging two of the planet’s most distant cities along a polar arc?

Singapore Airlines’ Flight SQ23 connects New York’s John F. Kennedy International Airport to Singapore Changi Airport non-stop in roughly 18 hours, depending on routing. Launched in 2020, the service covers about 9,536 miles, slightly longer than the airline’s earlier Newark–Singapore non-stop.
The route is flown exclusively on the Airbus A350-900ULR, the only production aircraft configured to make this ultra-long-range trip. Airbus built just seven of these extended-range A350s, tailored specifically for Singapore Airlines’ non-stop operations.
“When we introduced ultra-long-haul flying, we knew we had to rethink the entire in-flight experience,” said James Boyd, vice president of public relations at Singapore Airlines. “That meant reconsidering lighting, humidity, pressurization, airflow, dining and entertainment to help passengers feel better on arrival.”
Comfort is a primary focus on SQ23. Two full cabin crews work in shifts so service remains fresh throughout the journey. The aircraft’s custom layout removes a standard economy section, trading higher seat density for extra space and weight savings that help the aircraft reach its long-range performance.

Business class features a 1-2-1 layout so every passenger has aisle access and there are no middle seats. These seats are among the widest offered in business class—around 28 inches across on the ULR configuration—compared with 20–22 inches on a standard A350. Seats convert into fully flat beds and include mattress pads and extra pillows stored behind the seat. On boarding, passengers receive amenity kits with La LaBô lip balm, hand moisturizer and facial mist to help maintain hydration.
Premium economy uses a 2-4-2 layout with three rows of individual seats in the rear cabin. These seats recline about 8 inches and measure roughly 19 inches wide, offering more space than many standard aircraft seats. Singapore Airlines collaborated with wellness experts from Canyon Ranch to design an in-seat stretching routine tailored for premium economy passengers.

Entertainment and connectivity are scaled for the length of the flight. The airline offers nearly 2,000 on-demand options, including hundreds of movies and abundant music selections. Premium economy passengers have 13.3-inch screens, while business class features 18-inch monitors. Satellite Wi-Fi, provided via Panasonic Avionics’ global network, enables browsing, work and streaming for much of the journey.
Meal service is frequent and varied. Singapore Airlines offers its Book the Cook option on SQ23, allowing passengers to preselect dishes ranging from familiar American choices like pizza and burgers to Asian specialties such as Chinese pork rib noodle soup and stir-fried noodles. The carrier also partnered with Golden Door to create wellness-focused meal options intended to aid sleep, boost alertness, reduce inflammation or minimize bloating after larger meals.

Lighting plays a deliberate role in the onboard wellness strategy. The cabin’s LED system can produce more than 16 million color combinations, carefully chosen to encourage alertness or rest and to help passengers reset their circadian rhythms during the flight.
Time management helps make the long trip more manageable. “I recommend time blocking,” says Krista Ritterhoff, a travel publicist who has flown the non-stop route several times. “Treat the 18-hour journey as three six-hour segments—one for dining and entertainment, one for sleep, and one for work.”
Ritterhoff advises scheduling sleep in the middle portion of the flight to better adjust to the destination time zone and reduce grogginess on arrival. Falling asleep too early can leave you with long awake hours later in the flight and feeling dehydrated, while staying awake until landing can make it harder to adapt to the new day.
