The world’s longest commercial flight is poised to land at New York’s Newark airport after leaving Singapore yesterday.

The Singapore Airlines’ flight SQ22 was scheduled to cover the 15,000 kilometres from Singapore in 19 hours, although passengers were told it could take just 17 hours.

The flight left Singapore’s Changi Airport full with 150 passengers in business class and premium economy seats. The flight has no economy cabin.

Singapore Airlines has relaunched the service five years after it was cut because it had become too expensive.

The carrier said there was demand for customers for non-stop services which help cut travelling times compared with flights which have a stopover.
