The line cited government and health authority restrictions and limitations on border and port access, as well as the "continued uncertainty" around air travel.

Island Princess’s 2021 world cruise sailing from North America, including associated segments and remaining voyages sailing immediately prior to the departure, has been cancelled.

Meanwhile, Pacific Princess’s 2021 circle South America sailing from Australia, including its associated positioning cruises, has also been pulled.

“We share in the disappointment of this cancellation for guests of our world cruises because it’s a pinnacle cruise vacation experience, booked by some of our most loyal guests,” said Princess president Jan Swartz.

Guests booked on these cancelled voyages will receive a refundable future cruise credit equivalent to 100% of the cruise fare paid, plus an additional non-refundable bonus FCC equal to 25% of the cruise fare paid.

Alternatively, guests can forfeit the bonus FCC and request a refund for all money paid. Guests have until 30 September to opt for a refund, or they will automatically receive the default FCC offer.

Princess has vowed to protect travel agent commissions on bookings for cancelled cruises that were paid in full, "in recognition of the critical role they play in the cruise line’s business and success".
