KLM voucher code - October 2026

Extra baggage allowance for Flying Blue Silver members

Silver tier members receive one additional checked bag free of charge on top of the standard allowance included with their ticket. The extra bag is added automatically when you log in with your Flying Blue number during booking.

Free seat selection for Flying Blue Platinum and Gold members

Top-tier Flying Blue members can choose standard seats at no extra charge on KLM-operated flights, including preferred locations near the front of the economy cabin. Silver members get a discount on seat selection fees instead.

Best price guarantee on klm.com bookings

Find a lower KLM fare for the same flight, cabin and travel dates on another UK website within 24 hours of booking and KLM will refund the difference. Submit a claim through the online form with screenshots of the cheaper fare.

Multi-city trips from the same low base fare

Planning several stops? KLM's multi-city search tool lets you combine up to six flight segments in one itinerary, often at a lower total cost than buying separate one-way tickets. Useful for open-jaw routes like flying into Amsterdam and back from Paris.

Featured destination of the week with special fares

Each week KLM highlights a specific city with promotional pricing on return flights from the UK. The featured route changes every Monday and the offer typically runs for seven days or until the allocated seats sell out.

Group booking discounts for 10 or more passengers

Travelling with a large party? KLM's group desk offers special rates and flexible payment terms for bookings of ten people or more on the same flight. Contact the group reservations team for a tailored quote rather than booking online.

Last-minute getaway fares on unsold seats

When flights have remaining capacity close to departure, KLM may release reduced fares to fill them. These appear in the standard search results for dates within the next few weeks, so try flexible date searches to spot the best late deals.

Business Class deals on selected long-haul destinations

Premium cabin fares to intercontinental destinations are periodically reduced during KLM's promotional periods. Check the offers page for current featured routes, as discounts rotate between regions and are not available on every flight.

Book early for the lowest fares on popular routes

KLM's advance booking fares tend to be cheapest when tickets go on sale around 11 months before departure. Prices typically rise as the travel date approaches and seats fill up, especially on peak holiday routes during school breaks.

Save on flight and hotel packages with KLM Holidays

Bundle your KLM flight with a hotel stay through KLM Holidays and pay less than booking each separately. Destinations across Europe and beyond are available, with package prices shown alongside flight-only options during the booking flow.

Children fly at reduced rates on family bookings

Infants under two travel on a parent's lap for a fraction of the adult fare, while children aged 2-11 receive discounted ticket prices on most routes. When booking, enter the correct age for each passenger so the reduced fare is applied automatically.

Discounted youth fares for travellers under 26

KLM offers special fares for young passengers on many European routes. Eligible travellers must be 25 or under on the date of travel. Availability varies by destination and booking period, so search with your date of birth entered to see qualifying prices.

BlueBiz: free corporate travel programme for small businesses
