What are the longest commercial flights in the world?

Australian airline Qantas said Monday it will launch the world’s longest non-stop commercial flights by the end of 2025, connecting Sydney with London and New York in just over 19 hours aboard an Airbus A3500-1000.

Only a handful of companies offer non-stop flights over such a long distance, posing issues of aircraft capacity, economics and even crew and passenger health.

Here are some of the longest flights in the world in terms of time in the air:

Singapore Airlines flight SQ24, connecting the city-state to New York’s John F. Kennedy International Airport, is the world’s longest commercial flight to date. On board an Airbus A350-900, passengers cover this journey of more than 15,000 kilometers.

The Singapore company also offers the second longest flight in the world. The SQ22 takes 18 hours and 25 minutes from Changi Airport in Singapore to Newark Airport in New Jersey, near New York.

Currently Qantas’ longest flight, QF9, is a daily long-haul route between Darwin in Northern Australia and London. Passengers travel almost 14,000 km on board a Boeing 787 Dreamliner.

This flight originally departed from the western city of Perth but was relocated to Darwin due to Covid-19 restrictions in Australia. Qantas said it would resume the Perth-London route this year.

Singapore Airlines Flight SQ35 connects the city-state with Los Angeles on the west coast of the United States in 17 hours and 10 minutes, more than 14,000 km.

The airline’s San Francisco-Singapore route takes 16 hours and 40 minutes.

Hong Kong-based Cathay Pacific announced in March that it plans to operate the world’s longest passenger flight due to a route change between New York and Hong Kong.

This route would be longer than Singapore Airlines flight SQ24 to JFK. The flight route will cover “just under 9,000 nautical miles” — or 16,668 kilometers — in 16 to 17 hours, the airline told AFP in a statement.

According to Bloomberg, she declined to comment on why her trajectory avoids Russian airspace, through which she has flown in the past.

Many airlines have canceled routes to Russian cities or are avoiding Russian airspace because of the Russian invasion of Ukraine.

Cathay Pacific said the decision was made due to “strong seasonal tailwinds.”
