Alitalia 20% Off Weekend Sale

Got plans to head to Europe this summer?  Alitalia is having a special 20% off sale this weekend.  The only caveat is you must book on Alitalia’s Italian site here, and put “SPECIAL20IT” in the promo code box after selecting your fare.  Not only is the sale good for transatlantic flights, but also short-haul trips within Europe.
