Chase Ultimate Rewards points transfer to Air France/KLM Flying Blue at a 20% bonus through May 27, 2026. Every 1,000 Chase points becomes 1,200 Flying Blue miles instead of the standard 1,000. If you have UR points in a Chase Sapphire account and have been considering a Flying Blue award, this window is worth acting on.
How the Bonus Works
The standard Chase UR to Flying Blue transfer ratio is 1:1. During this promotion (May 1 through May 27, 2026), that becomes 1,000 UR to 1,200 Flying Blue miles. The bonus applies to any transfer of at least 1,000 points. Chase credits the bonus miles within 7 days of the transfer, so factor that in if you are booking a specific award.
The math at scale: 50,000 UR becomes 60,000 Flying Blue miles. 100,000 UR becomes 120,000 miles. For awards that sit just above a redemption threshold, even a small transfer goes further than it normally would.
Which Chase cards qualify: You need a card that supports partner transfers. The Chase Sapphire Preferred ($95 annual fee, last verified 2026-03-22) and the Chase Sapphire Reserve ($795 annual fee, last verified 2026-03-31) both transfer directly. The Chase Freedom Flex, Freedom Unlimited, and Ink Business Cash earn UR points but cannot transfer to partners on their own. You need to pool those points into a Sapphire or Reserve account first, then transfer from there.
Why Flying Blue Is Worth Considering
Air France/KLM Flying Blue is the loyalty program for Air France, KLM, and their SkyTeam alliance partners, which include Delta and Korean Air. Two things make Flying Blue useful for Chase cardholders:
Promo Rewards: Flying Blue releases discounted award pricing on the first of each month. These Promo Rewards cut award costs by 25 to 50 percent on specific routes. The selection rotates monthly, but common appearances include US to Paris (CDG), US to Amsterdam (AMS), US to Caribbean destinations, and intra-Europe routes. If you are flexible on dates and destination, Promo Rewards regularly surface options at lower mile costs than comparable portal bookings.
SkyTeam access: Flying Blue miles can book partner awards on Delta, Korean Air, and other SkyTeam carriers. For Chase cardholders who also fly Delta, Flying Blue provides an alternative redemption path, since Delta SkyMiles cannot be transferred out of Delta. Award pricing for Delta flights via Flying Blue is dynamic and should be checked at booking time.
When to Transfer (and When to Hold)
Transferred points are permanent. Once you move UR to Flying Blue, those miles stay in Flying Blue until you redeem them. Flying Blue miles do not expire as long as your account shows activity every 24 months, so you will not lose them, but you do lose the flexibility that makes UR points valuable across multiple programs.
Transfer makes sense when: You have confirmed award availability on a specific route. You are matching a current Promo Reward to a trip you are already planning. You need a top-up to cross a redemption threshold. For example, if you have 52,000 Flying Blue miles and need 60,000 for a specific award, transferring 7,000 UR in this window costs roughly 5,834 UR points before the 20% bonus rounds up.
Hold your UR points when: You do not have a specific redemption confirmed. You are planning a World of Hyatt stay (Hyatt transfers through UR remain consistently high-value and are not available through Flying Blue). You hold the Chase Sapphire Reserve and have a portal booking that qualifies for Points Boost on select premium flights or hotels.
How to Transfer
Log in to your Chase account and go to the Ultimate Rewards portal. Select Transfer to Partners and choose Flying Blue. The current 1.2x ratio will display during the promotion period. Transfers post immediately to your account request; Flying Blue credits the base miles and the 20% bonus within 7 days.
Transfers are processed in increments of 1,000 UR points. The minimum is 1,000 UR points. There is no stated maximum for the promotion.
Earning More UR Before You Transfer
If this promotion has you thinking about building UR points ahead of a future Flying Blue opportunity, here are the relevant earning rates from the eligible cards.
The Chase Sapphire Preferred earns 3x points on dining and most travel purchases, and 5x on bookings made through Chase Travel (last verified 2026-03-22). Points are worth 1.25 cents each through the Chase Travel portal, which gives you a baseline for comparing a transfer against a portal booking.
The Chase Sapphire Reserve earns 3x on dining and travel, and 10x on hotels and car rentals booked through Chase Travel (last verified 2026-03-31). New cardholders who applied after October 26, 2025 have a 1 cent per point baseline through the portal, with Points Boost available on select premium flights and hotels. Cardholders with accounts opened before October 26, 2025 retain the 1.5 cents per point value through October 2027.
The Freedom Flex and Freedom Unlimited both earn UR points that can be pooled into a Sapphire or Reserve account, then transferred. If you carry multiple Chase cards, combining your balances before transferring is worth the extra step.
Bottom Line
The Chase UR to Flying Blue 20% bonus runs through May 27, 2026. If you have confirmed award availability on an Air France, KLM, or SkyTeam partner flight, this bonus means you need fewer UR points to book it. The strongest use case is matching the transfer to a current Flying Blue Promo Reward. If you do not have a specific redemption in mind, keep your UR points flexible until you do.
