For the uninitiated, Flying Blue is the loyalty program for Air France, KLM, and a few smaller airlines, and Promo Rewards is the program's monthly promotion to discount award flights by 25% on select routes operated by Air France and KLM. Flying Blue may discount any combination of economy, premium economy, and business-class awards, depending on the route.
Flying Blue's May 2025 offerings let travelers book awards from nine North American airports to Europe starting at just 18,750 miles each way in economy. Unfortunately, Flying Blue's January devaluation means Flying Blue Promo Rewards now require more miles, but it's still a great deal.
This month, Flying Blue's Promo Rewards travel window extends through the end of October 2025. That means travelers can book up to six months out and lock in these low award prices. Here's a look at the new Flying Blue Promo Rewards and how to maximize them for cheap award travel.

Flying Blue Promo Rewards Routes for May 2025
Each month, Flying Blue discounts select economy, premium economy, and/or business class awards. For bookings in May 2025, the following nine North American cities are discounted:
- Atlanta (ATL): 25% discount on economy class (from 18,750 miles)
- Boston (BOS): 25% discount on economy class (from 18,750 miles)
- Miami (MIA): 25% discount on economy class (from 18,750 miles)
- Minneapolis (MSP): 25% discount on economy class (from 18,750 miles)
- Phoenix (PHX): 25% discount on economy class (from 18,750 miles)
- Salt Lake City (SLC): 25% discount on economy class (from 18,750 miles)
- San Francisco (SFO): 25% discount on economy class (from 18,750 miles)
- Washington, D.C. (IAD): 25% discount on economy class (from 18,750 miles)
- Montreal (YUL): 25% discount on business class (from 45,000 miles)
But if you head a bit farther south, there’s another Flying Blue Promo Rewards route. This month, you can also book business class awards from St. Martin starting at 63,750 miles. It’s a solid deal if you reside in St. Martin — or if you’re up for booking a positioning flight there to enjoy a longer transatlantic crossing.
New Flying Blue Promo Rewards Award Pricing
In late 2023, Flying Blue standardized award rates between the U.S. and Europe — but then devalued these “starting at” prices in January 2025. Now, all routes start at 25k Flying Blue miles in economy, 40k in premium economy, or 60k in business class. That means a 25% discount reduces award rates between North America and Europe as low as:
- 18,750 miles each way in economy.
- 30,000 miles each way in premium economy.
- 45,000 miles each way in business class — or 63,750 miles if you fly from parts of the Caribbean and Central America
Example Flying Blue Promo Rewards Awards
Throughout this month's booking window, availability is generally good for flights between North America and Europe, in all eligible classes. Here are some examples of the Flying Blue Promo Rewards you can book during May for travel through October of this year:
Economy between North America and Europe for 18,750 miles
Flying Blue's cheapest Promo Rewards from North America to Europe are a bargain. And there's plenty of availability, too, starting at 18,750 miles. For instance, here's what the Flying Blue award calendar shows as available between Boston (BOS) and Amsterdam (AMS) this September:
If you want to fly further, you can do that too. Flying Blue will allow you to add a connection within Europe (and as far as Turkey) for no extra mileage cost. For example, you could fly an itinerary like Boston to Athens, Greece, via Amsterdam for just 18,750 miles plus taxes and fees.
Business class between Montreal and Europe for 45,000 miles
Nowadays, it's not very often that Flying Blue discounts business-class awards. But for this month, you can book awards between Montreal (YUL) and Europe for as little as 45,000 miles plus taxes and fees.
Better yet, we're seeing tons of availability between Montreal and cities like Amsterdam — even during the summer months.

Our Take
Flying Blue Promo Rewards offers an amazing opportunity to maximize your points and miles. The list of destinations available in May is something to behold (at least compared to previous months), and there's tons of availability — even during summer!
The disappointing thing, though, is that the days of 15k-mile awards to Europe via Flying Blue are over. So, this deal isn't as good as it used to be.
But if this deal piques your interest, you can book discounted awards through October 31, 2025, as long as you make your reservation by May 31, 2025. Travel between North America and Europe is available most months for as low as 18,750 miles in economy. And it can cost even less if you're able to take advantage of an ongoing transfer bonus.
Since Flying Blue is a transfer partner of all major transferable points programs, you can redeem for discounted awards no matter which points you collect. If there's no Promo Reward available from your airport, Flying Blue still offers several sweet spots outside of these monthly discounts.
