Those flying in and out of Sydney Airport today are encouraged to check individual airlines for flight delays as the coast of NSW is battered by strong winds.

The Bureau of Meteorology has recorded winds reaching up to 67 kilometres an hour at Sydney Airport in Mascot, and up to 69 kilometres an hour at Sydney Harbour.

At the time of writing, Virgin Australia, Qantas and Jetstar flight statuses showed approximately 70 domestic and international flight delays in and out of Sydney.

Qantas has already had to cancel 26 flights as winds have been preventing takeoff.

“Due to strong winds at Sydney Airport today, Air Traffic Control has imposed a single runway operation affecting a number of Virgin Australia flights,” a Virgin spokesperson told ABC News.

Just after 1.30pm, Sydney Airport’s Twitter account confirmed delays would continue into the afternoon and only one of the three runways is currently in use.
