Carnival Cruise Line has announced that it will resume operations in North America from 1 August with eight ships from Miami, Port Canaveral and Galveston.
The operations in the remaining North American and Australian markets will continue to be suspended until 31 August.
Last month, Carnival Cruise Line suspended all its operations around the world until 26 June amid the Covid-19 pandemic.
All North American cruises will be cancelled from 27 June to 31 July.
From 1 August, Carnival Dream, Carnival Freedom and Carnival Vista will operate from Galveston, Carnival Horizon, Carnival Magic and Carnival Sensation from Miami and Carnival Breeze and Carnival Elation from Port Canaveral.
The Carnival Spirit Alaskan cruises from Seattle and the Carnival Spirit Vancouver-Honolulu cruise on 25 September and Honolulu-Brisbane transpacific cruise on 6 October have also been cancelled.
All of the Carnival Splendor cruises from 19 June to 31 August in Australia will be cancelled.
The passengers affected by the cancellations will be informed via email and will be able to either receive a full refund or combined future cruise credit (FCC) and onboard credit (OBC) package.
Carnival Cruise Line said: “We are committed to supporting all public health efforts to manage the Covid-19 situation. We are taking a measured approach, focusing our return to service on a select number of homeports where we have more significant operations that are easily accessible by car for the majority of our guests.
“We will use this additional time to continue to engage experts, government officials and stakeholders on additional protocols and procedures to protect the health and safety of our guests, crew and the communities we serve.”
