Jax's longest flight so far was about 5 hours. When we told him some flights last almost an entire day, he couldn't believe it. Here are the routes where planes fly the farthest without stopping.

Top 5 Longest Flights

Airline: Singapore Airlines
Distance: 9,537 miles

How Do Planes Fly So Far?
Ultra-long-range planes carry HUGE amounts of fuel. An Airbus A350 on the Singapore-New York route carries about 43,000 gallons of fuel — that's enough to fill a swimming pool!
These planes are also designed to be extra lightweight and fuel-efficient. They use special engines and materials to travel farther on less fuel.
What's It Like on a Super Long Flight?
Airlines make these flights as comfortable as possible:
- Meals are served multiple times
- There are hundreds of movies and TV shows to watch
- The cabin lights change color to help your body adjust to the time zone
- Some airlines have special stretching areas where you can stand and move around
Fun Math
If the longest flight is about 9,500 miles and takes 18 hours, the plane is traveling at about 528 miles per hour. That's almost as fast as the speed of sound (767 mph)!
