How to Survive Long-Haul Flights

Long-haul flights are generally considered to be those eight hours and over, while any that stretch past a grueling 16 hours are nicknamed “ultra long-haul.” The longest nonstop commercial flights currently available include New York to Singapore (18 hours and 50 minutes; 9,530 miles) and Perth, Australia, to London (17 hours and 45 minutes; 9,010 miles).

Packing a change of clothes (if there is a stopover, you may be able to find a shower in the airport) as well as a toothbrush and toothpaste will go a long way to helping you feel fresher during your journey. Make sure you’re wearing comfortable clothing and a pair of compression socks to combat swollen feet from so many hours with little physical activity.

“Wear a hoodie,” recommends Nikki Greenberg, 40, a futurist and innovation strategist from Sydney who frequently travels internationally for work. “It is cozy, warm, covers the ears (less noise) and eyes (less light for sleep), and creates a private cocoon environment.”

Find a way to sleep as much as possible

Do anything and everything you can to make sure you spend a large chunk of the time onboard asleep. Some travelers consider sleeping pills or melatonin supplements as must-haves, while eye shades and…
