Cruise lines say no change on sailing plans after new COVID-19 cases

Royal Caribbean Group and Carnival Corp will push ahead with a return to cruises this summer despite two guests onboard Royal Caribbean's Celebrity Millennium ship testing positive for COVID-19.

A year after several cruise ships were host to major coronavirus outbreaks and with large numbers of Americans now vaccinated, cruise lines have been striving to get business going. Shares in Royal Caribbean, Carnival Corp and Norwegian Cruise Line Holdings Ltd fell between 1% and 2% in response to the report of the positive tests.
