Transport minister Mable Chan said officials met the senior management of Greater Bay Airlines on Wednesday morning over its cancellation of 128 flights between February and March.

Chan said authorities want a detailed report from the firm in around a week.

The day before, the airline cited a delay in new aircraft deliveries and statutory safety inspections of existing aircraft as the reason for the cancellations, which will affect 5,500 passengers to places like Japan and South Korea.

The budget airline added on Wednesday that negligence in its flight scheduling process was found following an internal review, but flights over the Lunar New Year period would not be affected.

Speaking after attending a Legislative Council meeting, Chan said the government wants a detailed report on matters such as remedial measures in around a week's time, noting the airline had already submitted some initial figures to officials.

"The Transport and Logistics Bureau and the Civil Aviation Department have already met with senior management of Greater Bay Airlines, to learn more about the way forward," she told reporters.

"Our message is very clear. We told the company that it must protect the rights of affected travellers, and that it must do its best to minimise the effects on passengers through various means."

Chan said aviation authorities meet with airlines regularly, and they require firms to submit regular financial and operational reports to ensure that they are run in a robust manner.

She described the existing regulatory regime as comprehensive.

The minister said Greater Bay Airlines should learn from this experience, noting that it's a growing firm that her bureau wants to help in the process.

Chan expressed hope the airline could be more flexible in scheduling flights in future, by adding buffers in areas such as manpower and computer systems.
