Well, that seems a reassuring and reliable airline. From their website:
airports throughout Wizz Air's network will be performing medical screening of passengers, therefore it is possible you may be subjected to such a check upon arrival at your destination airport.
Wizz Air shall not be obliged to pay the compensation if the cancellation is caused by extraordinary circumstances
Wizz Air does not offer a refund when the trip is voluntarily cancelled by the passenger.
It is the traveller’s responsibility to verify travel restrictions in a given country with the local authorities and ensure their admissibility to enter/exit a given country. Please also make sure your health condition allows you to travel and will not have an effect on other passengers.
I received a notification that I was a passenger on a flight with a confirmed coronavirus case. What should I do?
Please contact your local health authority immediately and follow any guidance that is given.
My impression is that Wizz are happy to take people's money and either dump them in the arrival airport or just tell them to fuck off if they realise and try to cancel. They probably figure it's cheaper to fly the planes empty than refund everyone.
They have already had confirmed cases on flights and the help they provided is to email people's travel agents after the event.
Next month? Good news? Crazy. Yeah, that.
