, the flight length is defined as the time airborne during a flight.
Short-haul flight: <3 hours
Medium-haul flight: 3 to 6 hours
Long-haul flight: >6 hours

Domestic

A short-haul domestic flight is commonly categorized into being no longer than 500 mi (804.7 km) 1.5 hours in length, meaning that all domestic flights within a country such as the United Kingdom

 are short-haul. In addition to this criterion, the destination airport must be in the same country as the departure airport. Domestic flights can vary greatly in length due to some countries being larger than others.

Long-haul flights

Long-haul flights are journeys typically made by wide-body aircraft

A wide-body aircraft is a large airliner with two passenger aisles, also known as a widebody aircraft or twin-aisle aircraft. The typical fuselage diameter is . In the typical wide-body economy cabin, passengers are seated seven to ten abreast, allowing a total capacity of 200 to 850 passengers...

Great circle distance and other factors

A flight will typically take a direct route to minimise flight length. For long-haul flights, the most direct route is a great circle

However, a flight route will also take into account weather conditions, and air currents. A transcontinental flight in an Easterly direction will often take a more southerly route to take advantage of the jet stream
