Royal Caribbean Cruises has extended its fleet lay-up again, to 11 June, because of coronavirus.

The Richard Fain-led cruise major with 62 vessels decided in mid-March to drop anchor on its fleet until 30 April in a concerted move with peers Carnival Corp and Norwegian Cruise Line Holdings.

New York-listed Royal Caribbean then extended that lay-up to 11 May, before continuing it into June.

Its latest move comes after the Centers for Disease Control (CDC) imposed a 100-day cruise ban within US territories.

"Now, after consulting with our partners at Cruise Lines International Association and in conjunction with the CDC, our global suspension has been extended — all sailings departing on and before June 11th, 2020 will be cancelled," the company said.

"While our goal was to resume operations for most of our ships on May 12th, 2020, we will now resume our operation June 12th for the majority of our fleet."

Carnival Corp has suspended its Carnival Cruise Line fleet until 26 June and its Princess Cruises and Seabourn fleets to 30 June, following initial plans to resail those ships on 13 April.

Norwegian Cruise Line Holdings has suspended its fleet until 10 May and MSC Cruises until 29 May.

Other cruise companies that have laid up their ships include Viking Cruises and Saga Cruises through April, Fred Olsen Cruises until 23 May and Crystal Cruises through May.

Cruise providers are providing 100% refunds or future cruise credits as high as 125% to passengers whose voyages have been cancelled as a result of the fleet suspensions.
