AIDA Cruises will not sail any ships to the US or Canada until next year amid both countries' ban on passengerships.
The US has an entry stop for Europeans until further notice, while Canada is not allowing cruise calls through October.
"In expectation of a normalisation of tourism, AIDA Cruises is working intensively on detailed plans for a speedy restart," the Carnival-owned German brand of 13 vessels said on Friday.
"However, as a result of the continuing effects of the coronavirus, the conditions for international travel to the USA and Canada are not currently in place."
Refund or rebook
AIDA Cruises will inform all affected guests and provide them a full refund or the chance to rebook their voyages through 2021 with a 10% added cruise bonus.
"AIDA regrets very much that it is not possible to offer guests the unforgettable holiday experience they had hoped for at the moment," the company said.
"The focus is now on developing a framework of policies and procedures for a restart. In doing so, AIDA is taking into account the forthcoming openings in European travel."
AIDA Cruises will also give travel agents a "liquidity advance" equal to 10% of cruise credit values once AIDA Cruises issues travel credits to joint customers.
Repeated delays
The big three cruise majors have pushed back fleet restart dates numerous times over the past few months.
Carnival's P&O Cruises prolonged its fleet suspension once again on Tuesday, this time to 15 October after previously setting a date of 31 July.
Royal Caribbean's 62 vessels will stay at anchor into June, while Norwegian Cruise Line Holdings delayed its restart four times to the end of July.
Other companies that have laid up their ships include Viking Cruises and Saga Cruises , Fred Olsen Cruises and Crystal Cruises. MSC Cruises is also not sailing.
US two-ship outfit Bahama Paradise Cruise Line does not plan to sail again until 25 July, and Greek line Celestyal Cruises will not sail until 30 July.
Further extensions on fleet lay-ups may happen as the US Centers for Disease Control has banned all cruiseships from US territories until late July.
