Norwegian Cruise Line, Oceania Cruises and Regent Seven Seas Cruises are dropping pre-departure COVID tests on many sailings.
However, pre-cruise tests will still be mandatory for some departures, including all those from the US, Canada, Greece and Bermuda.
In a statement, Norwegian Cruise Line Holdings, which owns all three lines, said that from 1 August guests would only need to test where required to do so by local regulations.
