Now as for the Wizz flights to Moscow, Wizz will never operate direct flights from Luton to Moscow, period.
Virgin is still trying to get permission to fly LHR to Moscow as it is a controlled route.
I pointed out in an earlier post that it would be via one of its hubs.
It will be possible via BUD in the future, if Wizz get approval from the 18 December up to 4 days of the week for a limited period and daily from the 4th June until mid September.
