Cunard, P&O Cruises and Princess Cruises have extended their balance payment due dates 

The three Carnival UK brands originally had a 90 day deadline on balance payments, but they have now extended that to 120 days, meaning customers are required to pay their outstanding fees 30 days sooner than before.

The change affects all bookings made from 10 March while all existing bookings will retain the 90 day deadline.

A spokesperson for the lines said: “We have extended our balance payment deadline for new bookings made on or after 10 March 2026 from 90 days to 120 days before departure.

“This change applies to all fare types and cruises sailing from 1 December 2026. Existing bookings are not affected.”
