Cruises possible by mid-summer as tensions boil over - CDC

U.S. cruises could resume by mid-summer with restrictions, the Centers for Disease Control and Prevention said Tuesday after Carnival Corp., the largest operator, threatened to relocate ships to other markets.

The agency’s signal sent shares of cruise companies rising in after-market trading, with Carnival gaining as much as 4.9%. Royal Caribbean Cruises Ltd. and Norwegian Cruise Line Holdings Ltd. also advanced. The industry has been pressuring the agency, saying it is restricting their return to the seas even as other hospitality industries like hotels and theme parks reopen.
