Which is the longest airline route in the world?

In the last few decades of the development of air travel, airlines have been able to provide nonstop service connecting longer and longer segments of the globe. This allows passengers to move from one city to another without the need to disembark and get on a new flight mid-journey. So just how long can these ultralonghaul flights be? As we speak, what remains the longest airline route in commercial aviation today?

Defining the Longest Route

The longest airline route is used most often as a reference point for the longest distance between the departure and arrival points. This is also known as the great circle distance, in other words, the distance between two points on the surface of a sphere which is the Earth in this case.

Therefore, the longest route is the direct nonsale scheduled air carriage of passengers, mail, and cargo between two airports with the greatest distance between the point where aircraft depart and the final point where they arrive. This does not take into account the distance traveled, or the time that one is on a particular flight.

To be precise several ultralong haul routes could be potential contestants for this title. But there can be some small changes in the flight timetables and the routes, so that is why the ranks can change from year to year. As for today generally, there is an agreement regarding the top 23 airlines that provide the longest nonstop flights in terms of distance.

The Top Contenders

In recent years, these three routes have alternated as being the absolute longest: In recent years, these three routes have alternated as being the absolute longest:

1. Singapore Airlines flight numbers 21 and 22 between Changi Airport Singapore International (SIN) and New Jersey's Newark Liberty International Airport (EWR) near New York state. This route is about 15,344 kilometres and it would take 18 hours and 25 minutes of flight time.

2. Auckland AKL to Dubai DXB Emirates flight number 449 nonstop service. Spanning 8,824 mi (14,193 km), this route can over 17 hours depending on the wind.

3. Some of the routes flown by the company include the direct route between Doha, Qatar (DOH) and Auckland, New Zealand (AKL) on flight numbers QR920 and QR921. It covers a distance of 7,845 miles (12,637km) and it is among the longer routes having 18 hrs and 20 mins of duration.

Some other ultralonghaul competitors that can also be sometimes on the list of the top 5 longest flights are Qantas with a route network connecting Perth Airport (PER) with London Heathrow Airport (LHR) and Dallas Fort Worth (DFW).

GameChanging Aircraft

The question is: What allows such an extensive nonstop flight? The main consideration here is factors such as the availability of more enhanced aircraft that can carry more fuel and other material to cover large distances such as the twinjet airliners. Particularly Airbus A350 XWB as well as Boeing's 777X & 787 dream liners make these ultralonghaul flights over oceans or continents possible.

The emergence of these revolutionary widebody jets with improved fuel-burning rates means that there is a possibility of undertaking long journeys without refueling. This is accompanied by the slimming of the body of the aircraft and lighter material used in manufacturing the planes, besides the engines that give out more power and at the same time consume less fuel. Modern advancements in aerodynamics turn into record-breaking nonstop flight distances.

Why Fly Over Many Hours?

But what would motivate airlines to provide such long services that much exceed 15 plus hours of flight duration? Did not most passengers rather utilize services that would take them shorter distances with one or more halts? There are several key reasons behind these point to point services: There are several key reasons behind these point to point services:

• Convenience Even when air time is as long as a marathon, people prefer flying a nonstop flight to having to wait for connecting flights.
• Time savings: However, the overall door-to-door traveling time can be less on an ultralong haul route due to reduced time waiting during interline transfers.
• Competitive Advantage Remember, getting record-setting routes is a plus for competitive airlines since it offers them prestige.
• Fuel Economy While there are certain parameters such as winds or the performance of the aircraft that might dictate it is more fuel efficient to ‘circle' over a location without stopping to refuel.
• Growth with increased advancement in aviation technology, it is logical that the reach of airline's nonstop flight distances will continue to increase in the future. One may consider the present innovation as radical and unimplementable, only to find it the new norm in the following years.

Challenges That The Longest Routes Present

However, such lengthy routes do pose many obstacles for airlines to grapple with, including: 

• Capacity and engineering Because an aircraft has a limited capacity and can only be engineered to hold a certain amount of fuel, it has certain strict limitations on the distance it can cover before it has to refuel. New plane designs still tend to push such boundaries.
• Fewer passengers There will be fewer passengers willing to travel such long distances nonstop or undertake very long-haul flights perhaps for exceptional reasons only.
• Tiredness As pilots, cabin crew, and other employees of the airline company also become weary from nearly full-day flights, calling for a backup team.
• Time change Fly too long and passenger/crews must quickly shift their internal clocks. Certainly, west coast flights challenge most of the human biological rhythms.
• Emergency contingencies When there is an unexpected landing, such as a precautionary one due to mechanical failure, it becomes worse if there are no nearby diversion airports.

ULH is the future of aviation, with some of the ULH routes being attributed to the future of aviation.

Present technology of airplanes has allowed for the longest flight to happen but there is always a drive to try and go farther without having to stop over. This kind of traveling may eventually revolutionize international routes for commercial space travel.

However, in the near term, expect the airlines to utilize new planes like the Boeing 7778X to provide unmatched services from point A to point B. Higher seating, range, and fuel for this aircraft could mean routes over more than 10,000 miles of distance. Future airplanes should keep on pushing the limits of how quickly long-range city pair air service can be maintained in the forthcoming years.

Yet as flight QR921 from Doha to Auckland is now shaping the record as today's longest airline journey, there can be sure to be more advancements in the aviation industry that will allow longer nonstop flights in the future. The expansion of business and commercial activity remains the major cause of concern as well as the main stimulus for further development of connecting the remotest points of the Earth.
