MIAMI — More cruise cancellations have been announced by Carnival Cruise Line, which is extending its pause in all operations in the United States through March 31, 2021.

In addition, select ships and homeport operations related to itineraries and dry dock work have been paused, says the cruise line.

Booked guests and travel agents are being notified directly of the cancellations and their options for a future cruise credit and onboard credit package, or a full refund.

The cancellations, brought on by the ongoing COVID-19 pandemic, include the following:

• All embarkations from U.S. homeports through March 31, 2021
• Carnival Freedom from Galveston through April 10, 2021, which includes a repositioning of the ship from Galveston to Seattle and a 17-day Carnival Journeys cruise that is not allowed under the current guidelines issued by the CDC
• Carnival Miracle from San Diego and San Francisco through Sept. 16, 2021, which includes many 10-day and longer itineraries not allowed under the current CDC guidelines
• Carnival Liberty from Port Canaveral from Sept. 17-Oct. 18, 2021 to accommodate rescheduled dry dock work
• Carnival Sunshine from Charleston from Oct. 11-Nov. 13, 2021 to accommodate rescheduled dry dock work
• Carnival Spirit’s 15-day cruise from Singapore to Brisbane on June 12, 2021 consistent with the current limitations on international travel in place in Australia

“We are sorry to disappoint our guests as we can see from our booking activity that there is clearly a pent-up demand for cruising on Carnival,” said Christine Duffy, president of Carnival Cruise Line. “We appreciate their patience and support as we continue to work on our plans to resume operations in 2021 with a gradual, phased-in approach.”
