daz211, I don't think alitalia is getting many bookings if any at all, as one must be out of the world or in a crazy mind to make one now. Only, they are not talking about it, comprehensibly.
Italian media already reported thta people with paid for tickets have no chance of alternate transport or compensation. Lot of people and companies will simply loose their money.
Anyway, negotiations are still in progress. I hope the unions won't accept, but you can never be sure.
