Norwegian Cruise Line Holdings Ltd. /zigman2/quotes/204183397/composite NCLH -4.68% said Tuesday that it was extending its global cruise suspension through April 30. The suspension now includes all cruises on its Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises.

The cruise operator had previously suspended all cruises through Feb. 28, and select cruises through March 31. Norwegian's suspension now matches that of Royal Caribbean Group /zigman2/quotes/208854639/composite RCL -5.44% announced last week, while Carnival Corp. /zigman2/quotes/202325446/composite CCL -4.85% said earlier in January that it would pause sailings of Princess Cruises through May 14. Although the Centers for Disease Control and Prevention (CDC) isn't suspending cruises, it currently recommends " all people avoid travel on cruise ships ," because the risk of COVID-19 on cruise ships is "very high."
