ANKARA, Turkey — Turkish Airlines says it is offering a 40 percent discount on airfares for health care workers across the globe.

The national flag carrier said Monday the campaign was aimed at people “who are working selflessly to combat the COVID-19 pandemic.” Up to three people traveling with a health care worker would be able to benefit from the discount, the airline said.

The tickets must be purchased before Aug. 1 for flights before May 31, 2021.

Turkish airline companies resumed domestic flights last week. International flights are scheduled to resume gradually as of June 10.
