Carnival Corp has delayed its restart for German brand AIDA Cruises by at least two months because countries around Germany are not ready to welcome back cruiseships, it said.

The New York-listed owner two weeks ago said it would start sailing 3,300-berth AIDAperla (built 2017) within Europe next month before sending other vessels into service.

Arnold Donald-led Carnival also said then that it planned to relaunch Costa Cruises' 2,260-berth Costa Deliziosa (built 2010) on 6 September and 4,947-berth Costa Diadema (built 2014) on 19 September.
