Flight length

From Wikipedia, the free encyclopedia
(Redirected from Long-haul flight)

In aviation, the flight length is defined as the distance of a flight. Commercial flights are often categorized into long-, medium- or short-haul by commercial airlines based on flight length, although there is no international standard definition and many airlines use air time or geographic boundaries instead (see Flight duration). Route category lengths tend to define short-haul routes as being shorter than 600–800 nmi (1,100–1,500 km), long-haul as being longer than 2,200–2,600 nmi (4,100–4,800 km), and medium-haul as being in-between.

Route category definitions

Lufthansa considers the Embraer E-190 as a short-haul airliner.
Lufthansa considers the Airbus A320 family medium-haul aircraft.
Lufthansa defines the Boeing 747-8 as a long-haul airliner.

Asia & Australia

  • Japan Air Lines defines routes to Europe and North America as long-haul and all other flights as short-haul. [1]
  • Virgin Australia defines domestic flights as within Australia, short-haul as those to South East Asia/Pacific and long-haul as those to Abu Dhabi or Los Angeles. [2]
  • Hong Kong International Airport considers destinations in North and South Americas, Europe, the Middle East, Africa, Southwest Pacific and the Indian Subcontinent long-haul and all others are short-haul. [3]


  • Eurocontrol defines medium-haul routes as being between 1,500 and 4,000 km (930 and 2,490 mi; 810 and 2,160 nmi), short-haul as shorter and long-haul routes as longer than that. [4]
  • The Association of European Airlines defined Long-haul as flights to Americas, sub-Saharan Africa, Asia, Australasia and medium-haul as flights to North Africa and Middle East. [5] The now defunct airline Air Berlin defined short- and medium-haul as flights to Europe/North Africa and long-haul as those to the rest of the world. [6]
  • Air France defines short-haul as domestic, medium-haul as within Europe/North Africa and long haul as the rest of the world. [7]

North America

  • American Airlines defines short-/medium-haul flights as being less than 3,000 mi (2,600 nmi; 4,800 km) and long-haul as either being more than 3,000 mi (2,600 nmi; 4,800 km) or being the New York–Los Angeles and New York–San Francisco routes. [8]
  • United Airlines defines short-haul flights as being less than 700 mi (610 nmi; 1,100 km) [9] and long-haul flights as being greater than 3,000 mi (2,600 nmi; 4,800 km). [10]

Aircraft category definitions

While they are capable of flying further, long-haul widebodies are often used on shorter trips: 40% of A350 routes are shorter than 2,000 nmi (2,300 mi; 3,700 km), 50% of A380 flights fall within 2,000–4,000 nmi (2,300–4,600 mi; 3,700–7,400 km), 70% of 777-200ER routes are shorter than 4,000 nmi (4,600 mi; 7,400 km), 80% of 787-9s routes are shorter than 5,000 nmi (5,800 mi; 9,300 km), 70% of 777-200LRs flights are shorter than 6,000 nmi (6,900 mi; 11,000 km) and 777-300ERs flights are evenly distributed across its range. [14]

Superlative flights

Shortest commercial flight

The Westray to Papa Westray flight in Orkney, operated by Loganair, is the shortest commercial flight in the world over 2.8 km (1.7 mi) in two minutes scheduled flight time including taxiing.

Longest commercial flight

The world's longest ever commercial flight was Air Tahiti Nui Flight TN64 [15] in early 2020. Due to the COVID-19 pandemic and the impossibility of transit in the USA through Los Angeles International Airport, Air Tahiti Nui scheduled and operated in March and April 2020 Flight TN64 as a non-stop flight between Papeete and Paris Charles de Gaulle, using a Boeing 787-9 and covering 15,715 km (9,765 mi; 8,485 nmi). [16] [17]

From November 9, 2020, Singapore Airlines SQ 23/24 is the world's longest active commercial flight between Singapore and JFK Airport New York City, USA. covering 15,349 km (9,537 mi; 8,288 nmi) in around 18 hours 40min and operated by an Airbus A350-900ULR. [18]


Absolute distance versus flight length

Airline routes between San Francisco and Tokyo following the most direct great circle (top) westward, and following a longer-distance jet stream route (bottom) when heading eastward

The absolute distance between two points is the great-circle distance, which is always the shortest geographical route. In the example (right), the aircraft travelling westward from North America to Japan is following a great-circle route extending northward towards the Arctic region. The apparent curve of the route is a result of distortion when plotted onto a conventional map projection and makes the route appear to be longer than it really is. Stretching a string between North America and Japan on a globe will demonstrate why this really is the shortest route despite appearances.

The actual flight length is the length of the track flown across the ground in practice, which is usually longer than the ideal great-circle and is influenced by a number of factors such as the need to avoid bad weather, wind direction and speed, fuel economy, navigational restrictions and other requirements. In the example, easterly flights from Japan to North America are shown taking a longer, more southerly, route than the shorter great-circle; this is to take advantage of the favourable jet stream, a fast, high-altitude tail-wind, that assists the aircraft along its ground track saving more time and fuel than the geographically shortest route.

Air time versus schedule times

Air time is the elapsed time that the aircraft is airborne, regardless of what time-zone the flight began and ended in.

Schedule time is the difference between the scheduled local time at the origin and the scheduled local time at the destination and usually differs from the actual time in the air as it is affected by the local time zones. Local clock time flying westward, or "chasing the sun", is slowed, [19] while local clock time flying eastbound is sped up. However, flights over the International Date Line located at approximately 180o E in the Pacific will subtract 24 hours from the schedule time going eastwards and add 24 hours going westwards. For example, the eastward flight shown in the example from Japan to North America will have a scheduled time of arrival earlier than the departure time, while from North America to Japan the flight will take a whole day longer by local time; the actual flying time in both cases being the same or similar.
