By Jonathan Levin (Bloomberg) — Cruise-line stocks led by Norwegian Cruise Line Holdings Ltd. climbed Friday after the Senate passed legislation to help the companies resume sailings to Alaska, a key destination for the industry during the North American summer. Norwegian was up as much as 7.4% to $28.39 in New York, its biggest gain in three weeks. Carnival Corp., the industry leader, rose as much as 7.1%, while Royal Caribbean Cruises Ltd. gained as much as 6.9%. The Senate measure seeks to get around Canada’s ban on cruising until 2022, which was enacted over concern about Covid-19. Maritime law bars foreign-flagged ships from transporting passengers directly between two U.S. ports, so Alaska voyages typically stop in Canada.
