September Flying Blue Promo Rewards

Last year we saw some incredible Flying Blue Promo Rewards for long haul business class out of the USA to Europe. Nothing compared to this May where we saw a ton of city pairs offering discounted business/economy that coincided with the Bilt Rewards 100% transfer bonus. For September, there are a number long haul Promo Rewards focusing on Economy out of numerous North American cities, but Mexico City is the only one offering a business class discount.

Flying Blue Promo Rewards for September – long haul

The prices you see below are between select destinations and Europe. So you’ll find different prices depending on where you finish/start your trip.

If you’re open to flying economy – NYC/Boston/Miami are offering some pretty great deals


STTP found that a few cities are discounting award rates even though they aren’t technically included

Each month, it seems that FlyingBlue buries some hidden award flights. Spencer, Straight To the Points, found some cities that are discounted but aren’t officially on sale.

  • Boston = 56k
  • Austin = 60k
  • LAX = 60k
  • JFK = 41.25k

For instance, here is a look at JFK

Great uses of Air France/KLM Flying Blue Miles

Air France Business Class

There are many great uses, but in particular redeeming miles for Air France business class is a wonderful use. Normal rates begin at 53k miles – this is a super competitive rate, but keep in mind a couple hundred in taxes and fees will also apply

Virgin Atlantic Upper Class

Starting as low as 61,500 miles and a couple hundred in taxes and fees its a great way to fly on a super cool product and pay fewer taxes and fees than Virgin Atlantic would charge


KLM Business Class

KLM offers world class service and a great business class – keep your eye out for the planes that offer reverse herringbone 1-2-1 configuration ( primarily the 787-9 ). I’ve flown both it and the 777-300ER and they are world’s apart in comfort…make sure you find the 787-9

    Can not book any flights with AF or KLM using the promo code. Tried multiple cities/dates, both websites, called customer service no help as you have to book with their flying blue tool which does not recognize any of the specials when you click on them, ( but if you want to pay full mileage price you can ) called flying blue customer service ( which is different from their regular customer service ) and after being on hold listening to banjo music for over 50 minutes I was told that all their reps were busy and I would have to call back and then the call was disconnected! Lousy customer service!

  • Emeka Nwani May 1, 2023

    No promos are showing on the Flying Blue website for May 2023. Is that occurring for everyone?

    • Miles May 1, 2023

      i’m seeing them still, they are just fewer and far between. this was been really well publicized so I wonder if they aren’t getting snagged. You’l find more if you search connecting cities, or if you look at routes back from Europe

      • Emeka Nwani May 1, 2023

        Usually on the Flying Blue website it gives you a list but I’m getting a notice saying “Unfortunately, there are no Promo rewards available. Nevertheless, you can book a regular reward to your destination via Air France or KLM websites”.

        Are you just searching destinations via the AF/KLM websites vs going through Flying blue? Thanks.

    Wow! I just booked 2 RT tix from Montreal to Milan in May!! I transferred I think it was 89,000 of my AMEX pts and it turned into more than 111,000 pts w this offer for the 2 business class tix. I’m pretty happy about this!

    I struggled to figure out how to do it but finally after trial and error with the website, I booked the flights.

    Now I need to get from Denver to Montreal. My husband has always wanted to go to Canada so we can stop there for a couple of days.

    Thank you for the tip!

  • Geoff December 1, 2022

    Wow, this gets weirder by the minute!

    When I select DTW from the Promo page, I get an Air France booking page, and it carried over my login ID and the Explorer tag, which I guess is a Flying Blue thing. It plugs DTW in the Arrival field, not the Departure field. Well, these are Europe-based carriers, so I guess I can see why they set it up this way. So I enter AMS in the departure field, and the system tells me “You must select both a departure and arrival city, and they must be different cities.” Well, they are different, so what’s this about???

    So I flipped it: I entered DTW in the Departure field, and AMS in the Arrival field. This time I get a different error: “Sorry, there are no flights available for this combination of departure airport, arrival airport and travel dates. ” Hmmm…This is the Air France site, so maybe I should shift to French cities.

    So I start over. System pops DTW in the Arrival field again, I enter CDG in Departure. Same result: “You must select both a departure and arrival city, and they must be different cities.” I flip the cities again (depart DTW, arrive CDG) and hit Search. Now I get the Months display, but no fares in either USD or points.

    Maybe the KLM site works better…I choose Montreal (YUL) from the Promos page because it has the KLM logo in the box, implying these fares are only good on KLM, not Air France. So here we go….

    KLM booking engine starts up, again with me logged in and the Explorer logo on the top margin. But it plus YUL in the Arrival spot. OK, I’m now used to that. I enter AMS in the Departure field, and I get the same error: “Please select both a departure and arrival city. They must be different cities.” But I hit Search anyway, and I get the Months display (hooray!) but with no USD or point fares displayed (boo-hoo). Just for grins, I poke a few random dates to see what will happen, and I get this error: “Sorry, there are no flights available for this combination of departure airport, arrival airport and travel dates. Please try again.”

    That’s just flat-out WRONG. Google Flights shows KLM 671 flying that route on all of the dates I chose.

    So once again, we’re tempted with a great-sounding offer but the booking engines prevent us from taking advantage of it, just like ANA (my current most-hated airline website).

    I welcome any suggestions about how to navigate this. I’ve wasted quite enough time for one night.

  • Geoff December 1, 2022


    Great post! No idea this existed. I joined FB just based on this post.

    One question: How can I see the various destinations for promo rewards? Do I have to enter DTW, YUL, etc as the departure airport and then choose every possible destination to find the bonus routes? Seems quite tedious! How did you find the bonus destinations for this post?


  • Roberta December 1, 2022

    I cant get the departure date to stay blank. Im signed in and it requires it to be filled. Not signed in, it wont let me search. So Im unable to replicate your searches…bummer But I appreciate the insight on AF/KLM.

  • Elaine Almond April 11, 2022

    A few questions:
    1. Trying to research flights using Flying Blue and it is saying that no flights are available. I don’t have my miles transferred yet, so I have a zero mile balance. Will it not show me me the flights available to purchase with miles when you don’t have the miles available? I’m flying over the holidays so my dates are not flexible.
    2. Should I transfer the miles before I know if I can use them? So could I transfer them back if I can’t use them with Flying Blue?

    • Miles April 11, 2022

      Hey Elaine – it should show you avail whether you have award points or not, and no, unfortunately you can’t transfer miles back so you want to ALWAYS make sure there is availability before transferring otherwise you’ll be stuck with your points in that account and maybe have a better use for them elsewhere down the line.

      • Elaine Almond April 12, 2022

        So I guess they limit the amount of flights that can be taken with rewards points? The flights are there but when I search under the book with miles button, it says flights are not available??

  • […] New Flying Blue Promos:  Every month, Air France/KLM post their flying blue promotions where they offer award discounts on certain routes.  This month is extremely appealing because you’re able to stack this promotion with a transfer bonus for an amazing deal! […]

  • Sam April 5, 2022

    Thanks for this!
    If someone books an AF business award using flying blue miles but credits their delta skymiles account, will they still be eligible to a paid upgrade option based on availability, or is it better to stick with flying blue account all the way? Thanks in advance.
