Air France Flying Blue December 2025 Promo Rewards

The Flying Blue loyalty program, shared by Air France and KLM, has released its December 2025 Promo Rewards, offering significant mileage discounts on select routes worldwide. These monthly promotions are among the best opportunities for travelers to redeem miles at reduced rates, making long-haul and European travel more affordable. This guide explains everything you need to know about the December 2025 edition, including eligible routes, booking rules, savings, and strategies to maximize value.

What Are Flying Blue Promo Rewards?

Flying Blue Promo Rewards are discounted award tickets offered each month on specific Air France and KLM routes. These discounts apply to the program’s saver-level award fares, which are already the lowest mileage options available.

Key characteristics include:

Discounts typically range from 25% to 50% off the regular saver award price.
Available in Economy, Premium Economy, and occasionally Business Class.
Valid for both one-way and round-trip bookings.
Taxes, surcharges, and carrier fees are not discounted and must be paid in full.
Promo Rewards availability is limited and varies month to month.

Because Flying Blue uses a hybrid dynamic-pricing model combined with saver award charts, Promo Rewards allow travelers to secure lower award rates even during high-demand periods.

December 2025 Promo Rewards: Booking and Travel Window

For December 2025, the Promo Rewards are:

Booking window: December 1–31, 2025
Travel window: Through May 31, 2026

This provides nearly six months of eligible travel dates, allowing flyers to plan winter, spring, or early-summer European trips at significantly reduced mileage rates.

December 2025 Promo Rewards: Featured Routes and Discounts

Flying Blue continues its recent trend of including several U.S.–Europe routes as part of the monthly promotions. Below is an overview of the key deals available for December 2025.

Economy Class (Saver Award Pricing)

Starting from 18,750 miles one-way on select routes between Europe and:

Detroit (DTW)
Houston (IAH)
Ottawa (YOW)
New York (JFK)
Raleigh–Durham (RDU)
Washington D.C. (IAD)

These discounts reduce the typical economy saver rate from approximately 25,000 miles to just 18,750 miles, offering substantial savings for transatlantic travelers.

Premium Economy Class

Some routes are available from 30,000 miles one-way, reduced from the standard 40,000 miles. Premium Economy is a popular choice for travelers looking for improved comfort, upgraded seats, and better onboard service without the cost of business class.

Business Class (When Available)

Select long-haul or high-value routes occasionally appear with discounted rates:

Starting at 45,000 miles one-way, down from the standard 60,000 miles.

Although Business Class Promo Rewards sell out quickly, they provide exceptional value when available, especially for travelers seeking lie-flat seats across the Atlantic.

Why December 2025 Promo Rewards Are Worth Considering

Significant Mileage Savings

A 25% to 50% discount represents one of Flying Blue’s best redemption opportunities, especially for long-haul travel. Travelers aiming to stretch their miles or book multiple passengers benefit the most.

Flexibility for One-Way or Multi-City Trips

Flying Blue allows one-way award bookings, which gives freedom to mix airlines, combine itineraries, or build multi-city European trips at no extra mileage cost for intra-Europe connections.

Easy Miles Accumulation

Flying Blue miles are easy to earn because the program partners with major credit-card transfer programs such as American Express Membership Rewards, Chase Ultimate Rewards, Capital One Miles, and Citi ThankYou Points.

Consistent Transatlantic Coverage

Promo Rewards frequently include U.S.–Europe routes, making it a reliable monthly tool for finding discounted Europe travel.

How to Book Flying Blue Promo Rewards

Follow these steps to secure a discounted award seat:

Visit the Air France or KLM website and log in to your Flying Blue account.
Select “Book with Miles” as your payment option.
Enter your departure and destination cities.
Search for travel dates during the Promo Rewards travel window.
Look for award prices reflecting the discounted mileage rates (e.g., 18,750 miles instead of 25,000).
Complete the booking and pay the standard taxes and surcharges.

If you plan to use transferable credit-card points, transfer them to Flying Blue before booking. Most programs transfer instantly.

Important Considerations Before Booking

Promo Rewards have limited availability and book out quickly, especially in Premium Economy and Business Class.
Taxes and carrier surcharges can be substantial on some routes, particularly long-haul Air France flights.
Discounts apply only to saver-level availability. If saver seats are sold out, the Promo Reward will not appear.
Each month’s list is different, so specific routes for December may not return in January or future releases.
