Cathay Pacific Airways asked its 27,000 employees on Wednesday to take three weeks of unpaid leave while the Hong Kong carrier struggles with plunging revenue due to China’s virus outbreak.

In a video message to employees, CEO Augustus Tang said the situation is as grave as the 2009 financial crisis, The South China Morning Post reported.

On Tuesday, Cathay announced a 90% reduction in flight capacity to mainland China, which has cancelled group tours and told businesspeople to put off foreign travel while Beijing fights the outbreak centred on the city of Wuhan.

The airline cut 30% of its worldwide capacity for two months.

Employees were asked to take “special leave” sometime between March 1 and June 30, a Cathay statement said.

“Preserving cash is the key to protecting our business,” the airline said.

The airline used similar “special leave” in 2009 and during the 2003 outbreak of SARS, or severe acute respiratory syndrome, which also led to cuts in flights.

“I am appealing to each and everyone one of you to help,” Tang was quoted as saying.
