Norwegian Cruise Line, Royal Caribbean, Virgin Voyages, Disney Cruise Line and Carnival Cruise Line all issued additional cruise cancellations at the beginning of April.
The announcements are only the latest in a constant stream of cancellations throughout the first part of 2021.
Cruise lines have repeatedly pushed back their restart dates as they wait for additional guidance from the U.S. Centers for Disease Control and Prevention regarding the criteria to be used in the next phase of its Framework for Conditional Sailing order.

Norwegian Cruise Line
"The Cruise Line today canceled all July and August itineraries aboard Norwegian Breakaway, Dawn, Escape, Getaway, Sky, Spirit, Star and Sun," Norwegian said in an April 6 release. "In addition, voyages aboard Norwegian Epic through Sept. 1; and Norwegian Pearl through Nov. 7 have also been canceled."
Norwegian Cruise Line Holdings Ltd., Norwegian's parent company, canceled sailings until July on all three of its cruise lines, the company announced in a March release.
"The suspension now includes all voyages on Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises embarking through June 30," Norwegian said. "The company will continue to work in tandem with global government and public health authorities and its Healthy Sail Panel expert advisors to take all necessary measures to protect its guests, crew and the communities visited."
Princess Cruises said March 9 it would cancel all cruise vacations in the Caribbean, along the California Coast, in Mexico and in the Mediterranean through June 30, impacting departures from Los Angeles, Fort Lauderdale and Rome including those on Caribbean Princess, Enchanted Princess and Ruby Princess.
Holland America Line, Seabourn
Holland America announced March 9 that it canceled its European cruises departing through June 30. The new cancellations will impact cruises departing in May and June on Nieuw Statendam, Volendam and Westerdam.
Seabourn, Carnival Corp.'s luxury line said on March 9 that it "is maintaining its optimism for the ultimate restart of travel while, in the meantime, continuing to take a practical approach in extending its current operational pause," Seabourn said in a statement.
As a result, the brand is cancelling a selection of 2021 European departures pausing operations on its ships Seabourn Sojourn, Seabourn Encore and Seabourn Ovation until July 3 and Seabourn Quest until Nov. 7.
The cancellations come a couple of weeks after those lines announced they wouldn't sail in Alaska or Canada due to that country's decision to ban cruise ships in its waters until 2022.
Princess canceled its seven-day voyages of the Glaciers itineraries between Vancouver, British Columbia and Anchorage (Whittier, Alaska), as well as all Pacific Coastal itineraries that begin or end in Vancouver and Canadian Adventure round-trip sailings from Southampton, England.
Meanwhile, Holland America said it is canceling all cruises that begin or end at a Canadian port. The move affects the following itineraries:
Alaska: Multiple cruises from all departure points through September aboard Koningsdam, Nieuw Amsterdam, Noordam and Zuiderdam. (That also includes any Land+Sea Journeys connected with canceled Alaska sailings.)
Pacific Coastal: Two early October cruises aboard Koningsdam and Oosterdam.
Canada/New England: Three Zaandam cruises departing in September.
The Holland America statement added that "at this time, Alaska cruises departing from mid-May and sailing roundtrip from Seattle, Washington, are not being canceled," and it noted that cruisers who book to sail out of Vancouver will not be permitted to switch to Seattle instead.
Holland America and Princess noted that they were working with the United States and Canadian governments in hopes of salvaging some part of the 2021 cruise season for Alaska and Canada.
Seabourn announced in a statement that it is canceling all 2021 itineraries for Alaska and British Columbia. The moves affects 19 summer cruises on the Seabourn Odyssey.
Carnival Cruise Line
Carnival Cruise Line has canceled all voyages through the end of June, the line announced on April 6.
"In order to allow additional time for our return to service preparations, we have decided to extend the suspension of sailings for our global fleet through June 30th, 2021 – excluding sailings onboard Quantum, Spectrum, Voyager, Anthem, Adventure, Vision, Jewel, and Odyssey of the Seas," Royal Caribbean said in an announcement Thursday.
The cruise line plans to resume "further operation in July." The ships that are exempt from the order are scheduled to sail in different parts of the world.
Celebrity Cruises and Silversea Cruises itineraries through May 31 are canceled. Azamara, which Royal Caribbean Group is in the process of selling, has canceled voyages through June 30.
While Virgin Voyages announced August sailings in England on April 8, it also canceled sailings in U.S. waters until Sept. 22, when Scarlet Lady, its first ship, will sail from Miami, making its long-delayed debut.
Disney Cruise Line
Disney has canceled sailings on its Disney Magic ship through Oct. 9 during its European season, the company announced April 15. Instead, the Magic will hold a series of short voyages in the U.K. this summer that are only open to residents.
Additionally, Disney Cruise Line announced April 6 that all U.S. departures through June are canceled.
"We are carefully reviewing the recently released guidance from the U.S. Centers for Disease Control and Prevention and working toward resuming operations," Disney said in an announcement. "As we continue to refine our protocols for our eventual return to service, we are canceling all Disney Dream, Disney Fantasy and Disney Wonder sailings departing through June 2021."
