Hmmm. Given Alitalia’s long history of financial difficulties I’m not sure if this is good news but they are returning to SFO next year with nonstop service to Rome on Monday, Wednesday and Saturday. Service will be on B777 aircraft. Perhaps it may be best to purchase trip insurance that includes coverage for financial default.

More options and competition is good though.
