The length of a flight to Dubai from a particular location will depend on the distance between the two locations and the speed of the aircraft.
As a rough estimate, a flight from London to Dubai takes around 7 hours, while a flight from New York to Dubai takes around 17 hours. These flight times can vary depending on factors such as wind speed and direction, the specific route taken by the aircraft, and any layovers or stops along the way.
To get a more accurate estimate of the flight time from a specific location to Dubai, you can use a flight time calculator or check with an airline. It is also a good idea to factor in additional time for layovers and connecting flights if applicable.
