In a statement, the American river cruise operator said that despite "great efforts" by its team, operations were deemed unsustainable, adding that "guests should expect to have their cruise deposits refunded in full."
Despite previously unveiling plans for the year ahead, all future voyages have been cancelled.
Refunds can be requested via the cruise line's dedicated refund portal.
Fred. Holidays, the UK representative for American Cruise Lines, said it was "saddened to hear the news" about American Queen Voyages, but reassured agent partners that "American Cruise Lines offers a similar product" but has "no connection with American Queen Voyages."
Agents who have booked American Queen Voyages are invited to reach out to their Fred. Holidays' trade rep for additional support, including re-booking similar sailings or general booking advice.
