As above. I also suspect the 1st July will be exceptionally optimistic for any of the package tour operators to recommence.
Regardless of the logistics of all the above there needs to be an announcement of the FCO travel advice relaxation and also the mythical 'air bridges' to be established. These would need to be announced in the next couple of days to have any hope of a July 1st restart.
There's also the small matter of getting the workforce back into work and the no small task of getting the aircraft out of storage ready for service.
