This, following an advisory against cruise travel from the US-based Centers for Disease Control (CDC).

Carnival said in a press release that their decision will affect all embarkations from US homeports from January 1-31 and all embarkations on Carnival Legend out of Tampa through March 26.

The cancellation will also affect embarkations from Baltimore, Charleston, Jacksonville, Long Beach, Mobile, New Orleans and San Diego through February 28.

Carnival had previously cancelled certain other itineraries on four ships (Magic, Paradise, Valor, and Victory/Radiance) that are scheduled for required dry docks in the first half of 2021, with the plan to return them to operations after maintenance work and upgrades are completed.

Carnival previously cancelled operations in Australia through March 2, 2021.

Carnival said it is in the process of building a gradual, phased-in approach to resume guest operations, which will focus initially on Miami and Port Canaveral, to be followed by Galveston.

Consistent with CDC protocols, Carnival Horizon arrives in Miami this week, and Carnival Breeze will be the next ship back to the US.

Sixteen Carnival ships are currently following the CDC process for an eventual resumption of guest service in the US in 2021, including Carnival Conquest, Dream, Ecstasy, Elation, Freedom, Glory, Liberty, Miracle, Panorama, Pride, Sensation, Sunrise, Sunshine and Vista. Mardi Gras, which is under construction in Finland, will also enter service in 2021.

“We are committed to meeting the CDC requirements and keeping our guests and business partners informed of our progress,” said Christine Duffy, president of Carnival Cruise Line.

“The entire Carnival team appreciates the great support of our guests, travel advisors and business partners, and local officials in our homeports and destinations.
