Wizz Air sent an email that flights will resume:
Travel limitations imposed by local authorities to minimize the spread of coronavirus pandemic (COVID-19) are changing dynamically and always require immediate actions. Wizz Air has been fighting daily to accommodate instantly all the government decisions and to comply with new regulations, but many flights’ changes, including yours, are the unfortunate result of the unsuccessful negotiations between Wizz Air and local representatives (this time in Bulgaria) on operation of the flights in the new given circumstances.
We have tirelessly continued the negotiations and as a result we would like to gladly inform you
that there will be flights operated between Sofia and Luton in the upcoming days. In case it still fits your travel plans to fly, we kindly ask you to refer to our cancellation related e-mail, choose the rebook option and select the same route on a new date at your convenience (subject to availability of seats. If you made a different choice before, go to our website at
wizzair.com . or
https://wizzair.com/en-gb/information-and-services/mobile-app/mobile-app]mobile application. and book a new flight directly.
