Uncertainty around European ports of call has been blamed by P&O Cruises for a further cancellation of sailings into April 2021.

Passengers with bookings on a cancelled cruise will be notified and automatically receive a 125% future cruise credit or a refund by filling out a web form.

The latest pause affects sailings by Aurora, Arcadia, Azura and Britannia.

The company said: “With restrictions on travel constantly evolving, we feel it is necessary to extend our pause.

“These further cancellations vary according to ship and itinerary. We’ve also taken into account complexity and length of itineraries, advice and guidance regarding ports of call and current air availability for fly-cruises.”

P&O Cruises president Paul Ludlow said: “With hopeful news headlines clearly we do not want to extend our pause in operations any further than absolutely necessary, but given the ever changing guidance around international travel and the varying regulations in many European ports of call we felt it prudent to cancel these additional dates.

“In addition, as the final payments are due for these cruises very soon we felt it was the right thing to do for our guests.

“We are so sorry to disappoint those who were due to travel but really hope they will re-book for later in the year or for our new programme of 2022 holidays which went on sale earlier this month with strong demand, showing great confidence in cruising in the future.”
