Best P&O Ferries Discount Codes

P&O Ferries is currently running a range of route specific discounts. The lead deal is the 25% off Cairnryan to Larne returns of up to 28 hours, applied automatically at booking, and it is best for drivers making a short return crossing who do not need to stay overnight for longer than 28 hours. That is the primary offer on this page and the one to check first for short return trips on that route.

If you need a short return trip (Cairnryan to Larne) within 28 hours, use the 25% off return deal. It applies automatically to eligible returns with stays of up to 28 hours, is for new bookings only, and excludes vans and foot passengers. This is the simplest saving for a quick drive there and back.

If you want flexibility on Larne to Cairnryan fares, the 20% off Flexi and Fully Flexi fares is the one to pick. It is aimed at flexible ticket types, must be booked by 1 December 2026, and covers travel through 16 December 2027. If you value free changes or refund options built into Flexi fares, this 20% reduction on that fare class can be more useful than the short return discount.

If you are towing a caravan or trailer midweek on Cairnryan to Larne, the up to 50% off caravan or trailer part of the fare will usually give the biggest saving on the towing portion. It runs for travel Tuesday to Thursday, requires booking more than two days before travel and applies only to the caravan or trailer element; passengers and the towing vehicle are charged at the regular fare.

If you are travelling in a standard motorhome midweek, choose the no motorhome supplement deal. On selected midweek sailings the motorhome is charged at the same rate as a car, provided the vehicle is under 6m long and under 2.3m high and you book more than two days before travel.

If you plan Dover to Calais travel or short breaks, the 15% off long breaks or single tickets for Dover to Calais, the Hull to Rotterdam 15% early booking offer, the day trips from £65 and the 3 or 5 day short break deals are the relevant options. Day trip and short break prices are route specific and availability bound, so check the advertised starting fares and the travel windows shown.

Our records show 10 offers listed for P&O Ferries in the 12 months to November 2026, and the biggest percentage sale in that time was up to 50% off (November 2026). No team checks are recorded for this brand in the same period.

When you choose between offers, pick whichever reduces your full booking total the most. For Cairnryan to Larne short returns use the 25% automatic discount; for midweek caravan towing use the up to 50% caravan reduction; for flexible ticket needs use the 20% Flexi deal. There is no general stacking rule shown on these offers, so assume only one of the listed discounts will apply unless the terms say otherwise.

P&O Ferries sells ferry crossings for passengers and vehicles, with routes linking Cairnryan and Larne, Dover and Calais, and Hull and Rotterdam. You can also book mini cruises and accommodation deals, so you can compare a crossing on its own with options for a longer break.

Onboard facilities include dining, shopping and entertainment, with cabins available on relevant services. Check the facilities for your chosen route rather than assuming every ship offers the same extras. For a holiday with your own vehicle, compare the full booking total, including any accommodation or onboard services you choose.

Promotions include early booking offers, seasonal sales and deals for particular routes or lengths of stay. Frequent Dover to Calais travellers can also compare season tickets. The lowest advertised fare is only useful if its travel dates, vehicle conditions and ticket flexibility suit your plans.

Start by checking whether an offer needs a discount code or applies automatically. Follow its booking instructions and check the total before paying. Route offers can be restricted by travel dates, ticket type, vehicle or length of stay, so match the conditions to your whole journey rather than just the departure port.

• Early booking offers: Compare these when your plans are settled, but read the ticket change and cancellation conditions before committing.
• Route deals: Look at the deals for your specific crossing. Day trips, short breaks and longer stays can have different promotional fares.
• Newsletter alerts: Sign up for offers and discounts by email. Treat this as a way to hear about promotions, rather than assuming registration gives an immediate saving.
• Season tickets: If you regularly use Dover to Calais, compare the season ticket terms with buying crossings separately.
• Accommodation offers: Check partner accommodation deals alongside your ferry fare, then compare the combined cost with booking each part separately.

The English booking site supports EUR. Online and phone bookings accept major credit and debit cards and PayPal, although available payment methods can vary by country and booking channel.

Ferry tickets have booking and cancellation conditions rather than a retail returns policy. Change fees and refund eligibility depend on your route, ticket type and circumstances. Before paying, compare these conditions as well as the fare, particularly if your travel dates might change.

The terms provide refunds or alternative arrangements for certain delayed or cancelled sailings. Keep the conditions for your chosen crossing to hand, and use the Help Centre when you need assistance with a booking.

For a journey between Ireland and Scotland, compare the Larne to Cairnryan crossing. Larne is in Northern Ireland, so include the journey to the port when working out your total travel cost from the Republic of Ireland.

If your holiday continues to mainland Europe through Britain, Dover to Calais and Hull to Rotterdam are separate crossings to consider. Allow for the overland journey between ports rather than comparing ferry fares alone.

Vehicle details matter when choosing a deal. Motorhome, caravan and trailer promotions can have size restrictions or apply only on selected weekdays. Check those conditions against your vehicle and both travel dates before deciding that a promotional fare is the cheaper option.

If you are comparing ways to make your journey, check the offers on Omio alongside your ferry fare. You can also browse our travel offers when planning the rest of your trip.

How do I use a P&O Ferries discount code?

Follow the offer’s booking instructions and apply your discount code before paying. Check that your route, ticket type and travel dates meet its conditions, then review the total before confirming.

Why might my discount code not work?

Check the booking deadline, eligible travel dates and any route or fare restrictions. Some deals apply automatically rather than requiring a code.

Which crossing should I consider for travel between Ireland and Scotland?

P&O Ferries sails between Larne in Northern Ireland and Cairnryan in Scotland. If you are travelling from the Republic of Ireland, include the journey to Larne when comparing your travel options.

Can I change or cancel my booking?

Change and refund conditions depend on your ticket type and circumstances, so compare the fare terms before paying. Separate terms cover refunds or alternatives for certain delayed or cancelled sailings.

How else can I save at P&O Ferries?

Compare seasonal sales, early booking offers and deals for your chosen route, or join the newsletter for offer updates. Frequent Dover to Calais travellers can also compare season tickets.
