Qatar Airways has launched what it says is the longest current non-stop commercial route, after completing a journey from Doha to Auckland.
Flight QR920 landed on Monday after 16 hours and 23 minutes, slightly quicker than expected.
The Boeing 777-200LR jet was showered with water cannons on arrival – a tradition for airlines on new routes.
Carriers like to talk up these records, but how are they measured and do they really matter?
Longest (time) or furthest (distance) are the two key distinctions to make, but it’s not as simple as it might sound.
Qatar Airways’ new route maybe the longest by time. But the 14,535km (9,032 miles) trip is not the longest existing flight by distance – a claim currently held by Air India’s Delhi to San Francisco route which is 15,127 km.
The distance between two cities doesn’t vary for airlines of course, but they might choose to take alternate routes. For example, a carrier might choose to avoid flying over certain countries which can alter how far a plane flies from point A to point B.
But regardless of the route, flight time is dependent on headwinds or tailwinds.
For example Qatar’s return leg form Auckland to Doha is expected to take about 18 hours because of headwinds.
“The longest flying time doesn’t always correspond with the longest distance,” says Ellis Taylor of Flightglobal.
“Of course, from a passenger perspective, the flying time is probably the best measurement. ”
Record-breaking flights may make headlines. But new long-haul flights mean nothing if they’re treated as a standalone route, says Mr Taylor. Rather, it’s what a new route brings to the airline’s existing network.
“On its own, it wouldn’t be viable to fly between Auckland and Doha, but Qatar is focusing on the passengers from Auckland going on to Europe, Africa, the US or elsewhere,” says Mr Taylor.
“In that light, even though it may take some time for the route to stack up from a profit perspective, it may help the economics of its wider network. ”
Historically, most of the major long-haul routes have been serviced by legacy airlines like Singapore Airlines and Australia’s Qantas.
But adding new routes have allowed newer airlines like Qatar, and perhaps most notably Emirates, to expand their business very rapidly.
“It’s also about reach for Middle East airlines striving to outdo each other,” says Geoffrey Thomas of Airlineratings.com.
Longest flight records will continue to change hands as airlines launch new routes, and the range capability of aircraft improves.
Last year, for example, Qantas revealed it would fly direct between Perth and London from March 2018, a flight that will take 17 hours.
The price of fuel and the types of planes which airlines buy will be the determining factors in opening new routes
“With the arrival of the 777-8X in 2022, new records such as flights from Sydney to New York and Sydney to London will be set,” says Mr Thomas. “The 777-8X will be the ultimate long haul airliner. ”
But remember, for routes to be viable, they also require people to buy tickets.
That depends on passengers being willing to sit in their seats for 16, 17 or maybe 18 hours at a time. How long that desire will last (especially for travellers cramped up in economy) is something airlines will monitor carefully.
