Two Carnival Corp brands and a smaller line have again extended their fleet suspensions as the Covid-19 shutdowns ease slowly worldwide.

AIDA Cruises and Costa announced on Wednesday that neither brand would sail before 31 July, while Greek line Celestyal Cruises will not sail until 30 July.

In a statement, AIDA said many of its destinations are adjusting their regulations around international tourism but have not yet set specific conditions for cruise sailings.
