Can’t remember if your favorite ship has returned to sailing after the prolonged shutdown of the cruise industry? The uncertainty is nearly at an end because, as of this summer, cruising will have completed its comeback.All the major big-ship cruise lines – Carnival Cruise Line, Celebrity Cruises, Holland America, Norwegian Cruise Line, Princess Cruises and Royal Caribbean – have announced that nearly 100% of their fleets will be operational by the end of June. For summer vacations and beyond, cruisers will have the broadest selection of ships to sail since the pandemic began.For cruise news, reviews and tips, sign up for TPG’s cruise newsletterSome cruise lines will be fully back well before the quarter’s end. “With the opening of the Alaska season in May, Carnival will have returned its entire fleet to service, less than 10 months after resuming operations,” the company said in a recent press release.Norwegian Cruise Line is on the same schedule. “All of our vessels are expected to sail by early May and in time for the peak summer season,” Frank Del Rio, the president and CEO of the cruise line’s parent company said in its Q4 2021 earnings call.Royal Caribbean will have its entire fleet in service by the end of May, Holland America will be back in full force by mid-June and Celebrity Cruises’ last ship debuts in late June.Princess Cruises had planned for all but one of its ships to return to service by the end of June. However, with the recent reopening of Australian ports to cruise ships, the line’s Australia-based Coral Princess will set sail in June instead of September 2022.The cruise industry ramped up slowly after it was shut down for more than 15 months due to the COVID-19 pandemic. In North America, the first ships didn’t welcome passengers onboard until June 2021, and the lines gradually expanded their operations throughout 2021 as destinations opened up and the CDC granted them permission to sail from U.S. ports.This year had a rough start that saw cruise lines pulling ships from service due to the omicron surge, but with new CDC guidance, mask mandates falling and more destinations opening back up to cruise ships, the major cruise lines are looking forward to welcoming more passengers on their full fleets from a large roster of U.S. and international-based ports.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
