Greece this week suspended all flights from Doha following the positive results of 12 passengers on a flight from Doha to Greece.
The airline has released a message stating that all 91 passengers on the flight had tested as negative during departure.
Greece tested the passengers and found 12 positive for COVID-19. As a result, flights from Doha have been suspended and all passengers on the flight are in quarantine.
The suspension of Qatar Airways flights until 15 June has caused problems for those wishing to travel to Greece from Australia as the air carrier is the only provider of flights between the two countries.
Qatar has had 63,741 confirmed cases of COVID-19 in the country and 45 deaths.
