As we've seen with JetBlue and Qatar, Turkish Airlines has decided to put out a great offer for healthcare workers and their loved ones. They're offering 40% off both economy and business class flights after you register. While not free, 40% off business class on Turkish is pretty much unheard of, so if business is your thing, this offer may be better than earlier ones we've seen.
40% Percent of Turkish Airlines Flights Timeframe: 12. Jun. 2020 - 31. May. 2021
