Sydney flight chaos stretches into second day

Almost 40 domestic flights had been cancelled by Saturday morning.

Air traffic controller Airservices Australia told the airport it was likely just one runway would be operating later in the day due to strong winds. 

Thousands of passengers were left scrambling to find new flights on the first day of NSW school holidays.

A spokesman for Sydney airport said any passengers with concerns should speak to airlines directly.

Hawaiian Airlines has been contacted for comment.
