The Great Reopening: Are Cruise Lines Open in 2021?
As the world slowly emerged from the grips of the pandemic in 2021, travelers found themselves asking a critical question: Are cruise lines open 2021? After a year of suspended operations, port closures, and unprecedented uncertainty, the cruise industry began to cautiously resume services, but with a host of new protocols, restrictions, and safety measures in place. The allure of the open sea, exotic destinations, and onboard luxury remained undiminished, but the journey to get back on the water was far from straightforward. For many, the dream of sailing the Caribbean, exploring the Mediterranean, or cruising through Alaska was still alive—but it required careful planning, flexibility, and a deep understanding of the new normal.
In 2021, the cruise industry faced a delicate balancing act: restoring operations while ensuring passenger safety, complying with evolving health regulations, and rebuilding traveler confidence. Major cruise lines such as Carnival, Royal Caribbean, Norwegian, and Princess Cruises launched phased restarts, often beginning with short, domestic sailings or “cruises to nowhere.” These trial voyages were critical in testing new health and sanitation protocols, including enhanced ventilation systems, contactless check-ins, and mandatory pre-boarding testing. While not every line was fully operational, the industry’s commitment to a safe, responsible return to sailing offered hope to millions of would-be cruisers. This guide will explore the status of cruise lines in 2021, the safety measures implemented, destination availability, and practical tips for planning your next voyage in a post-pandemic world.
Which Cruise Lines Were Operating in 2021?
Major Cruise Lines Resuming Service
In 2021, the major cruise lines adopted a staggered approach to reopening, with some launching operations earlier than others based on regional regulations, port availability, and internal readiness. Carnival Cruise Line began limited sailings in July 2021 from U.S. homeports like Miami and Galveston, initially offering 3- to 5-night Caribbean itineraries. These voyages were open only to fully vaccinated passengers (ages 12 and up), with unvaccinated children requiring medical exemptions and additional testing.

Royal Caribbean International took a more aggressive stance, launching its first U.S. cruise in June 2021 with the Freedom of the Seas from Miami. The line introduced the “Healthy Sail Panel” protocols, developed in collaboration with medical experts, which included mandatory pre-cruise PCR or antigen testing, mask requirements in indoor public areas, and enhanced air filtration systems. By August, Royal Caribbean had over 10 ships sailing from the U.S., including longer 7-night Caribbean itineraries.
Norwegian Cruise Line resumed operations in July 2021 with the Norwegian Encore, sailing from Seattle to Alaska. The line required 100% vaccination for passengers and crew, a policy that set it apart from some competitors. Norwegian also implemented “Cruise with Confidence,” a flexible booking program allowing changes or cancellations up to 24 hours before departure.
Princess Cruises began its comeback with the Caribbean Princess in August 2021, offering 7-night voyages from Port Everglades. The line partnered with the CDC and local health authorities to ensure compliance with all U.S. and international regulations. Similarly, MSC Cruises and Costa Cruises resumed European sailings in the Mediterranean as early as June 2021, with strict testing and vaccination mandates.
Regional and Niche Operators
Beyond the big names, several regional and luxury operators also returned to the seas. Holland America Line launched its first Alaska cruise in July 2021 with the Nieuw Amsterdam, while Regent Seven Seas Cruises resumed service in September with the Seven Seas Splendor in the Caribbean. River cruise lines like Uniworld and AmaWaterways began European river sailings in the summer, often with smaller ships and lower passenger counts, making it easier to enforce social distancing.
For adventure seekers, Lindblad Expeditions and Hurtigruten resumed polar and coastal cruises in Norway and Alaska, focusing on small-group, nature-based experiences. These niche operators often had fewer regulatory hurdles due to their smaller scale and remote itineraries.
Lines That Delayed or Canceled 2021 Sailings
Not all cruise lines were able to resume operations in 2021. Disney Cruise Line canceled all U.S. sailings through at least October 2021, citing the complexity of family travel and the need for extended planning. Celebrity Cruises delayed its U.S. restart to August, focusing instead on European sailings earlier in the summer. Some lines, like Crystal Cruises, suspended operations entirely due to financial challenges, though they later announced plans to return in 2022.
It’s important to note that the status of each line changed frequently throughout the year. Travelers were advised to monitor official cruise line websites, sign up for email alerts, and work with trusted travel advisors to stay updated on cancellations and new sailings.
Safety Protocols: How Cruise Lines Ensured Passenger Health
Pre-Cruise Health Requirements
One of the most significant changes in 2021 was the implementation of strict pre-cruise health screening. Most cruise lines required proof of full vaccination for passengers aged 12 and older (and later 5+ as vaccines became available for younger children). Unvaccinated passengers often faced additional hurdles, such as mandatory medical exemptions, enhanced testing, and limited access to certain onboard areas.

All passengers were required to submit negative COVID-19 test results within 72 hours of boarding. Royal Caribbean, for example, accepted both PCR and antigen tests, but required documentation from an approved provider. Carnival mandated a second test at the terminal, adding another layer of safety.
Travelers were also asked to complete health questionnaires 72 hours before departure, disclosing symptoms, exposure risks, and recent travel history. Some lines, like Norwegian, used mobile apps to streamline the process, reducing contact at the terminal.
Onboard Safety Measures
Once onboard, passengers encountered a transformed cruise experience. Enhanced sanitation became standard: high-touch surfaces (elevator buttons, handrails, restrooms) were disinfected hourly using EPA-approved products. Many ships introduced electrostatic sprayers for deeper cleaning during overnight hours.
Ventilation systems were upgraded with HEPA filters and increased air exchange rates. Royal Caribbean’s “Healthy Sail Panel” recommended at least 10 air changes per hour in indoor spaces, significantly higher than pre-pandemic levels.
Social distancing was enforced through capacity limits, spaced seating in dining rooms, and timed entry for shows and activities. Some ships reduced passenger loads by 20–50% to maintain space. Masks were required in indoor public areas (except when eating or drinking) and on tenders to ports.
Contactless technology was widely adopted: digital check-ins, mobile keycards, QR code menus, and app-based service requests minimized physical contact. Carnival’s “HUB App” allowed passengers to book dining, shore excursions, and even order room service without speaking to staff.
Medical Facilities and Outbreak Response
Each ship was equipped with dedicated isolation areas for suspected or confirmed cases. Medical staff were trained in pandemic response, with rapid antigen and PCR testing available onboard. In the event of an outbreak, cruise lines followed CDC guidelines for quarantine, contact tracing, and port disembarkation.
For example, when a passenger tested positive on a Royal Caribbean cruise in July 2021, the ship returned early, and all guests were offered refunds or future cruise credits. The line also implemented “Test-to-Sail” programs, allowing asymptomatic passengers to rejoin after a negative test.
Many lines partnered with third-party medical providers like MedAire to ensure 24/7 telemedicine support and emergency evacuation plans.
Destination Availability and Itinerary Changes
U.S. Homeports and Domestic Sailings
In 2021, most U.S. cruise lines operated from a handful of approved homeports, including Miami, Port Canaveral, Galveston, and Seattle. These ports had established agreements with local health authorities and the CDC, allowing for streamlined embarkation and debarkation.
Domestic “cruises to nowhere” were popular early in the year, especially when foreign ports were closed. These 3- to 4-night voyages stayed at sea, offering passengers a taste of cruising without international complications. However, by mid-2021, most lines transitioned to Caribbean and Alaska itineraries, as destinations reopened with vaccination requirements.
International Ports and Travel Restrictions
International cruising faced significant challenges. The Caribbean was the first region to reopen, with islands like St. Maarten, Aruba, and Barbados welcoming vaccinated cruisers. However, entry requirements varied: some islands required additional testing upon arrival, while others banned unvaccinated passengers entirely.
The European Union allowed cruise ships to dock from June 2021, but individual countries set their own rules. Italy and Greece required negative tests for all passengers, while Croatia allowed entry based on vaccination status alone. Mediterranean sailings often skipped ports with stricter regulations.
Canada banned cruise ships until February 2022, eliminating Alaska cruises that traditionally stopped in Vancouver or Juneau. As a workaround, lines like Princess and Holland America offered “round-trip Alaska” itineraries from Seattle, avoiding Canadian ports entirely.
The Baltic and Nordic regions saw limited operations, with Hurtigruten and Viking Cruises focusing on Norway and the UK, where domestic travel was permitted.
Flexible Itineraries and Last-Minute Changes
Cruise lines introduced dynamic itineraries in 2021, allowing for last-minute port changes based on health conditions. For example, a Royal Caribbean cruise might replace St. Thomas with a sea day if the island reported a surge in cases. Passengers were notified via email or the cruise app, often with compensation options.
Some lines offered “flexible ports” on booking, where the final destination was determined 30 days before sailing. This allowed cruise lines to adapt to changing regulations without canceling entire voyages.
Booking and Cancellation Policies: What You Need to Know
Refund and Credit Options
Flexibility was the hallmark of 2021 cruise policies. Most lines offered full refunds or future cruise credits (FCCs) for cancellations due to COVID-19. Carnival’s “Book with Confidence” program allowed changes up to 48 hours before departure, while Norwegian’s policy permitted cancellations up to 24 hours prior.
FCCs were often transferable and combinable with other offers, and some lines (like Princess) added a 10–20% bonus value to credits. However, travelers were advised to read the fine print—some credits expired in 12–24 months or required rebooking by a specific date.
Travel Insurance and Health Coverage
Comprehensive travel insurance became essential in 2021. Standard policies often excluded pandemic-related cancellations, so passengers needed “cancel for any reason” (CFAR) add-ons. Companies like Allianz and Travel Guard offered plans covering medical quarantine, trip interruption, and missed port calls.
Some cruise lines partnered with insurers to offer bundled protection. Royal Caribbean’s “Travel Protection Plus” included $25,000 in medical coverage and $1,000 in quarantine benefits. Norwegian’s “Cruise Assurance” program provided similar coverage at a lower cost.
Group Bookings and Special Offers
To boost bookings, lines launched aggressive promotions. Carnival offered “Buy One, Get One 50% Off” on select sailings, while Royal Caribbean provided onboard credit and free upgrades. Loyalty programs like Crown & Anchor Society and Latitudes offered double points for 2021 bookings.
Group bookings (10+ cabins) received additional perks, such as private events, complimentary gratuities, and waived cancellation fees. However, groups were subject to the same health requirements as individual travelers.
Tips for Planning Your 2021 Cruise
Research and Verify Before Booking
- Check official cruise line websites for the latest sailing status and protocols. Avoid relying solely on third-party sites, which may not update quickly.
- Verify port entry requirements for each destination. Use resources like the International Air Transport Association (IATA) Travel Centre or CDC’s Cruise Ship Travel page.
- Contact your travel advisor to confirm vaccination policies, testing timelines, and insurance coverage.
Prepare for the New Onboard Experience
- Pack extra masks and hand sanitizer, as supplies may be limited onboard.
- Download the cruise line’s app before arrival to complete check-in and health forms digitally.
- Bring a portable charger for your phone, as app-based services require constant connectivity.
Plan for Contingencies
- Book refundable airfare to avoid losses if your cruise is canceled or changed.
- Schedule extra days at your destination in case of quarantine or delayed disembarkation.
- Keep copies of vaccination records and test results in both digital and physical formats.
