Korean health officials reported 60 new confirmed cases of coronavirus and one additional death in South Korea on Tuesday morning. That bring the total number of confirmed cases in the country to 893, with eight dead.

The airline's social media has been flooded with people trying to get a refund on tickets or change their flights.

"Hi, I am trying to contact Korean Air service centre to cancel tickets to Korea," said one Facebook comment on Tuesday.

"It is impossible to get connected to your service representative! I was waiting on hold forever the past 2 days," reads another Facebook comment. "I have a reservation to fly to Korea in May and [am] very concerned about the current situation."

One person tweeted at Korean Air: "hi are you gonna cancel flights and refund ??? my mom wants to cancel but i think the 100usd cancellation fee is ridiculous considering that this is an unforeseen circumstance that she has no control over."

"I would like to know about flight cancellations and refunds due to coronavirus situation," tweeted another. "One of your cabin crew is confirmed positive with the virus and I am not confident in flying with Korean Air."

Korean Air is offering refunds on certain flights impacted by the coronavirus. The airline is offering refunds on tickets for flights through China, Hong Kong, and Taiwan purchased before January 28.

Additionally, Korean Air is offering refunds to passengers with "entry restriction regarding novel coronavirus," meaning if you can get a refund if you have recently visited a country for which another country issued a travel ban.

For example, if you recently visited China, you can get a refund on your flight into the US, which has barred foreigners who have visited China in the last 14 days.

The IATA is forecasting a 8.2% year-over-year reduction in demand in the Asia-Pacific region, resulting in a $27.8 billion revenue loss.
