Prior to this, the British firm had hopes of resuming in January. 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.”
