Cunard is offering free onboard credit and accommodation upgrades as part of its wave booking campaign.
Guests choosing selected 2021 and 2022 voyages of seven nights or longer until 1 March will receive up to $800pp to spend onboard for spa treatments, shopping or drinks.
Customers booking applicable voyages sailing on Queen Elizabeth from Southampton or Barcelona next year can take advantage of a complimentary upgrade on their suite or stateroom.
Cunard president Simon Palethorpe said: "As we start the New Year dreaming of future holidays, we’re making it even more enticing for guests to book one of our voyages through to 2023. And for added reassurance and flexibility, guests can book with confidence as all Cunard bookings can be moved unlimited times before the balance is due."
