Another Qantas A380 flight from the US had to be cancelled after it reportedly recorded the longest wait on Los Angeles International Airport’s tarmac since 2007, in the latest blow for the airline.
The cancellation of the Sydney-bound flight on Sunday night, Los Angeles time, came after a computer glitch at global distribution system provider Amadeus caused chaos on Sunday, the Australian reported.

An A380 flight from Melbourne to Los Angeles was cancelled on Monday because of a faulty fuel indicator after 443 people spent more than four hours on the plane waiting for take-off.

The latest problem also involved an indicator light, this time on the braking system.

Almost 400 passengers spent three-and-a-half hours on the plane before Qantas cancelled it for 24 hours.

US sources said this was the longest stretch passengers have had to wait on the Los Angeles tarmac since a computer glitch in August 2007.

Authorities have moved to impose fines of up to $US27,500 ($30,080) for US carriers leaving passengers stuck on a plane for three hours or more.

Flight QF93 from Melbourne to Los Angeles was initially delayed one-and-a-half hours because of a fuel gauge fault.

It was taxiing when the problem recurred, forcing take-off to be aborted.

Passengers remained on board while maintenance crews examined the problem. They were not allowed to disembark because of heightened security procedures for US-bound flights that made re-screening passengers impractical.

Qantas cancelled the flight altogether when it became apparent the crew would exceed their on-duty time limits.

The Los Angeles-Sydney and Melbourne-Los Angeles flights have since departed.
