Economy on world's longest direct flight will have extra legroom and 'wellness zones'

The economy seats for the what will be the world's longest non-stop commercial flight have been unveiled.

In 2025 Qantas will start running routes from Sydney to New York and London direct, with the journey likely to take between 19 and 20 hours.

That will make it a bigger slog than the Singapore to New York route which is just shy of 19 hours, and the Perth to London journey that currently comes in at 17 hours and 15 minutes on average.
