How long does the longest flight take?

There are only 24 time zones in the world, but does this mean that the longest and farthest flight distance of an airplane is 24 hours? This answer is obviously incorrect.

Geographical diversity makes geography feel very complicated, and it is easy to be confused with a slight mistake. Because the time zone map is a plan, but I believe that people who have a little knowledge of life and geography know that the earth is round, and it becomes shorter when a straight line is converted into a curved surface, so the longest flight will generally not exceed 24 hours.

The longest flight data obtained online is flight MH370, which has not yet reached its destination. Of course, the above is just a joke.

Seriously, according to the data analysis, the longest flight duration is 15- 18 hours (note that this is a direct flight! There will be a connecting flight in 30 hours. This is the longest flight data in the air under very smooth conditions. If there is turbulence or other forced landing, the extra time is another matter.

Give a few examples:

Doha, Qatar-Auckland, New Zealand; 18 hours. This is the latest data of February 17, which has also become the longest commercial direct flight route in history.

Dallas-Sydney; 17 hours.

Dallas-Hong Kong; 16.5 hours.

Atlanta-Johannesburg; 16.5 hours.

Los Angeles-Dubai; 16.5 hours.

Los Angeles-Jeddah; 17 hours.

New york-Guangzhou; 16 hours.

……

The above is a summary of some network data, which is subject to the actual situation.
