Six US transferable currencies still move 1:1 into Flying Blue. The September 8 unbundling does not change the transfer ratios; it changes which mileage number you should use when you decide whether to transfer at all.
Which six currencies still transfer
American Express Membership Rewards, Chase Ultimate Rewards, Citi ThankYou Rewards (premium cards), Capital One Miles, Bilt Rewards, and Wells Fargo Rewards all transfer to Flying Blue at 1:1. Marriott Bonvoy continues at the less efficient 3:1 plus the occasional 5,000-mile bonus. U.S. Bank Altitude Reserve holders gained access in August 2026, but the card remains closed to new applicants. Transfers from the six remain the practical routes for most US holders.
The honest transfer-decision math now
Treat the Standard mileage price as the true cost of an Air France or KLM metal award. Light keeps the old headline number but is a restricted product for non-elites: fewer or no checked bags, paid seat selection, no lounge access even in business, and no changes or refunds. Paying the extra 25–30 percent for Standard restores the package most people previously assumed they were buying. Flex is only rational when the cash surcharge drop and free changes outweigh the large mileage premium.
Partner awards booked with Flying Blue miles remain untouched by the new tiers. When a Delta, Virgin Atlantic, or other SkyTeam partner award is available at a competitive rate, it often beats pure AF/KLM metal once Standard pricing is the baseline. Search both before any transfer. Do not move points on the strength of a Light number; move them only when a concrete Standard or partner award clears your personal cents-per-point threshold.
The pattern it fits
This is the second documented step in Flying Blue’s shift away from fully featured saver awards. The January 2025 saver-level increases (documented at https://www.bonuseagle.com/devaluations/program/air-france-klm) already raised the floor on many long-haul routes. The September 8 unbundling keeps the floor number visible while stripping the inclusions that made it useful. Flying Blue has been narrowing its famous values for years — its Israel-and-Morocco-as-Europe pricing, one of the program's legendary sweet spots, died back in 2018 and now rests in our Sweet Spot Graveyard.

What to do
Hold points in the bank currencies until a specific Standard or partner award is confirmed and priced. Compare the Standard mileage cost against the same itinerary on Virgin Atlantic, Aeroplan, or LifeMiles when those partners release space. Status (Silver and above) can restore some Light restrictions, but free changes still require Platinum. Transfer bonuses remain useful only when they apply to a Standard booking you already intend to make.
The bottom line
The six 1:1 transfer paths are intact. The decision rule is not. Standard is now the comparison price for AF/KLM metal; Light is a restricted product for non-elites; partner awards frequently win once that adjustment is made.
FAQs
Do any of the six transfer ratios change? No. All six remain 1:1.
When is Light still rational? Only for elites who regain bags, seats or lounges via status, or for travelers who accept non-refundable, no-bag tickets at the old mileage level.
Should partner awards be checked first? Yes. They sit outside the new tiers and often undercut Standard AF/KLM pricing.
Does a transfer bonus change the math? Only if the bonus applies to a Standard or partner award already identified; it does not make Light more attractive for non-elites.
