Delta Air Lines will let travelers with flights to South Korea change their plans without paying a change fee because of the spread of coronavirus.

South Korea reported 161 new cases of the COVID-19 virus Monday, and South Korea's president put the country under a red alert.

The Centers for Disease Control and Prevention has also recommended travelers avoid all non-essential travel to South Korea due to the widespread coronavirus outbreak. The CDC warned that there is "limited access to medical care in affected areas."

Delta said Monday that those with flights booked to, from or through Seoul through April 30 can keep their travel plans, change to a different flight without paying a change fee, or cancel the trip and use the value for a future flight.

The special terms apply to customers whose tickets were issued Feb. 24 or earlier.

Delta operates flights from Atlanta to Seoul, as does its partner Korean Air. The airline said it is working with customers to adjust travel plans.

Atlanta-based Delta had already issued a change fee waiver for flights to Beijing and Shanghai before suspending all of its flights to China earlier this month.
