On 20-Hour Flight, Lights Will Be Bright and Food Will Be Zesty

Qantas Airways Ltd. will ditch the traditional in-flight service routine for this weekend’s marathon nonstop trip from New York to Sydney.

At almost 20 hours, the unprecedented journey is set to be the world’s longest flight. It’s a key test run as Qantas prepares to start direct commercial services connecting Sydney with New York and London as soon as 2022.
