Are you guys sure that it's clever to not pro-actively cancel?
It looks like Alitalia is taking over the tickets from OTAs which means that they are in control of when to send the money back.

Given their recent liquidity problems and a financial situation close to bankruptcy I guess they will try to stretch the time until they pay you back to the maximum. Worst case: they go bust and you never see the money.

What they do right now is pretty smart:
Cancel all bookings that are SkyTeam, leave the *A and OW legs in the booking to hurt the competing alliance. Take over the booking so that OTAs can't cancel and they are in control of the liquidity.

They are hurting the competition, hurting error fare customers by taking their money and secure their own financial situation. That's how you make a bad situation to work in your favour, pretty impressive.
