Costa Allegra will never sail for Costa again Greg Dragonetti All Cruise Lines March 12, 2012 44As part of Carnival’s latest press release regarding their financials, Micky Arison, CEO of Carnival Corporation, stated that the Costa Allegra will not be returning to service with Costa Cruises. She will either be sold or scrapped in the next few months. She always seemed out of place in Costa’s fleet. Even more than the neoRomantica. Ok kidding on that last remark but really. The Allegra measures 28,500grt and is the oldest and one of the smallest ships in the Costa fleet.
