The group confirmed the latest round of suspensions on Tuesday (9 March). All Silversea and Celebrity Cruises sailings are suspended until 31 May.

All Royal Caribbean International sailings are also suspended to the end of May, excluding Quantum of the Seas, Odyssey of the Seas, Spectrum of the Seas and Voyager of the Seas.

Quantum resumed three- and four-night sailings in Singapore last year, while Odyssey will sail a range of three- to seven-night sailings for the Israeli market to Greece’s islands and Cyprus owing to the progress of Israel’s vaccination programme and its travel bubble with the two countries.

Spectrum and Voyager, meanwhile, are gearing up to resume operations in China next month, which will run into May.

All Azamara sailings are suspended through to 30 June; Royal Caribbean Group is currently in the process of selling the line to US private equity firm Sycamore Partners.

The group said it would continue to work with the US Centers for Disease Control and Prevention on a safe resumption of cruising, and through the industry-led Healthy Sail Panel.

"We are reaching out to our guests and travel partners to share further details," said the group in a statement.
