What Is The Longest Possible Flight?
The longest possible flight is 20+ hours long. If you want to know how long your flight will be, you can use this online calculator to find out. This is because the speed of an airplane depends on its wingspan and weight, which are both listed in pounds per square inch (PSI).
The fastest plane in the world is actually a Boeing 777-8 Dreamliner! It can fly at Mach 0.89, or 890 miles per hour!
Other longest flights are as below:
Qantas non-stop flight between New York (JFK) to Sydney, Australia
Qantas non-stop flight between New York (JFK) to Sydney, Australia
Flight time: 20 hours and 30 minutes
Distance: 9,529 miles
Airplane used: Boeing 787-9 Dreamliner
This route was launched in 2018 and is operated by Qantas Airlines.
Emirates non-stop flight between Auckland, New Zealand and Dubai, UAE
The Emirates non-stop flight between Auckland, New Zealand and Dubai, UAE is 17 hours and 30 minutes long. It has an average flight distance of 9,032 miles (16,312 km), which means you’ll have to fly for almost three times as long as a normal flight just to get there!
Qatar Airways non-stop flight between Doha, Qatar and Auckland, New Zealand
The longest non-stop flight is Qatar Airways’ QR920, which flies between Doha, Qatar and Auckland, New Zealand. The journey takes 17 hours and 55 minutes to complete and covers 8,578 miles (13,622 km).

Qantas non-stop flight between Perth, Australia and London Heathrow Airport in England
The longest non-stop flight in the world is between Perth, Australia and London Heathrow Airport in England. This route takes 17 hours and 30 minutes to complete, making it the longest flight on earth.
The Qantas Boeing 747-400 can carry up to 510 passengers at a time across this route; however, as of summer 2019 there are only two flights each day serving this route: one at 7am and another at 5pm (local time).
Conclusion
In the end, however, there’s no definitive answer to this question: it depends on how you want to look at it. If you want a more realistic assessment of travel times and distances, then let me recommend the following:
Calculate the total distance of each flight as well as its duration. 2) Add these two numbers together and divide by two (this will give us the average flight time). 3) Now subtract this amount from 20 hours to determine what time difference actually exists between cities like London or New York City with smaller airports like Perth, Australia; Doha or Dubai; Sydney or Auckland in New Zealand; Johannesburg or Cape Town in South Africa; etcetera!
