Singapore: A marathon flight of nearly 19 hours is launching in October — and there’s something familiar you won’t see on board.

Tickets have already gone on sale and will be the world’s longest commercial flight — a whopping 18 hour, 45 minute marathon from Singapore to New York.

Singapore Airlines has revealed more details about the record-breaking flight ahead of its launch on October 11. The flights will be daily beginning on Oct 18.

The 16,700km route between Singapore’s Changi airport and Newark Liberty Airport, Newark, New Jersey, will be the first airline to use Airbus' A350-900 ULR (for ultra long range) planes, which have extra fuel capacity, are made of a carbon fibre that is lighter than the aluminium of traditional jets and burn less fuel because they have only two engines, compared with the four on many other long-haul jets.

The non-stop flight is primarily meant to appeal to business travellers, which is why Newark airport was chosen as the New York gateway. It gives the airline easy access to business customers in Manhattan and in northern New Jersey.

The airline said there will be no economy seats on the flight, with only premium economy and business class seats available to passengers.

There will be 94 seats in premium economy — a class between economy and business class — and 67 business class seats.
