Air France and KLM are offering a flash Valentine sale with £50 off for bookings made by 20th February.
To get the credit you need to use the promo code UKVALDAY50 for Air France and KLUKLOVE50 for KLM.
They are valid on any long haul and European flights departing the UK operated by Air France / KLM with a minimum value of £160.

Tickets must be round-trip and purchased on the Air France or KLM websites, with travel between now and the end of June 2023. The promotion can be used in any cabin class.
The discount code can only be used 200 times, so you’ll want to move quickly if you see a fare you like.
The Air France site is here and the KLM site is here. Most flights show on both sites, irrespective of which airline is flying them, so if one code fails then try the other site with the other code.

How to earn Flying Blue miles from UK credit cards (June 2025)
Air France and KLM do not have a UK Flying Blue credit card. However, you can earn Flying Blue miles by converting Membership Rewards points earned from selected UK American Express cards.
These cards earn Membership Rewards points:
- American Express Preferred Rewards Gold Credit Card (review here, apply here) – sign-up bonus of 20,000 Membership Rewards points converts into 20,000 Flying Blue miles. This card is FREE for your first year and also comes with four free airport lounge passes.
- The Platinum Card from American Express (review here, apply here) – sign-up bonus of 50,000 Membership Rewards points converts into 50,000 Flying Blue miles
- The American Express Rewards Credit Card (review here, apply here) – sign-up bonus of 10,000 Membership Rewards points converts into 10,000 Flying Blue miles. This card is FREE for life.
Membership Rewards points convert at 1:1 into Flying Blue miles which is an attractive rate. The cards above all earn 1 Membership Rewards point per £1 spent on your card, which converts to 1 Flying Blue mile.
The American Express Preferred Rewards Gold Credit Card earns double points (2 per £1) on all flights you charge to it, not just with Air France and KLM but with any airline.
