Should You Transfer Chase Points to Flying Blue?

Air France-KLM Flying Blue is one of the most valuable frequent flyer programs for SkyTeam alliance redemptions, particularly for flights between North America and Europe. With this 20% bonus, there are several compelling reasons to consider a transfer:

Advantages of Transferring During This Promotion

Better award availability: Air France and KLM typically release more award seats to Flying Blue members than to partner programs
Competitive pricing: Flying Blue often offers the best award rates for transatlantic SkyTeam flights, especially after recent Delta SkyMiles devaluations
Monthly Promo Rewards: You can stack this transfer bonus with Flying Blue’s monthly Promo Rewards, which discount select routes by 25-50%
Instant transfers: Unlike some other programs, transfers from Chase to Flying Blue typically process immediately, allowing you to book as soon as you find availability

Sweet Spots with the 20% Bonus

Here are some of the best redemption opportunities when leveraging this transfer bonus:

Business class to Europe: One-way awards start at 60,000 Flying Blue miles (50,000 Chase points with the bonus)
Promo Rewards business class: If you find a route with a 25% discount, you could fly business class to Europe for just 45,000 Flying Blue miles (37,500 Chase points)
Domestic Delta flights: As low as 5,000 Flying Blue miles one-way (4,167 Chase points)
China Airlines business class to Taipei: 62,500 Flying Blue miles one-way from North America (52,084 Chase points)
North Africa connections: Countries like Tunisia and Algeria are included in Flying Blue’s “Europe” zone, offering excellent value

Considerations Before Transferring

While this promotion offers good value, there are several factors to consider before transferring your Chase points:

Expiration policy: Flying Blue miles expire after 24 months of inactivity, and transfers don’t extend the expiration of existing miles
Multiple transfer partners: Flying Blue partners with all major transferable points currencies (Amex, Capital One, Citi, and Chase), so you might want to save your Chase points for exclusive partners like World of Hyatt
Fuel surcharges: Flying Blue does impose carrier surcharges on many awards, which can add $100-300+ to the cost of a ticket
Dynamic pricing: While Flying Blue has some general pricing guidelines, award costs can vary based on demand and specific routes

Strategic Approach to This Transfer Bonus

There are three main strategies to consider with this promotion:

1. Transfer for Immediate Redemptions

The safest approach is to transfer points only when you have a specific redemption in mind and have confirmed award availability. This allows you to take advantage of the bonus while minimizing the risk of future devaluations or having miles expire.

Since transfers from Chase to Flying Blue are typically instant, you can search for availability first, then transfer the exact number of points needed once you’ve found a suitable option.

2. Speculative Transfers for Future Travel

If you’re confident you’ll use Flying Blue miles within the next 24 months and want to lock in the 20% bonus, a speculative transfer could make sense. This approach works best if:

You frequently fly routes served by Air France, KLM, or other SkyTeam partners
You have specific travel plans in mind, even if you’re not ready to book immediately
You already have some Flying Blue miles that you want to top off for a redemption

3. Stack with Flying Blue Promo Rewards

For maximum value, consider waiting for Flying Blue’s monthly Promo Rewards to be announced, then transferring points to take advantage of both discounts. Promo Rewards typically offer 25-50% off select routes, which combined with this transfer bonus can result in exceptional value.

For example, a business class flight to Europe that’s discounted to 45,000 miles through Promo Rewards would require just 37,500 Chase points with this transfer bonus—a fantastic deal for transatlantic premium cabin travel.

Alternative Uses for Chase Ultimate Rewards Points

Before transferring to Flying Blue, consider whether your Chase points might be more valuable when used with other transfer partners:

World of Hyatt: Often considered the most valuable Chase transfer partner, with points typically worth 1.7-2.0 cents each
United MileagePlus: For Star Alliance redemptions, especially with no fuel surcharges
British Airways Club: For short-haul partner awards, particularly on American Airlines domestic flights
Virgin Atlantic Flying Club: For partner awards on ANA, Delta, and Air France

Chase Ultimate Rewards points are among the most flexible and valuable currencies in the points and miles world, so it’s worth considering all options before committing to a transfer.

Bottom Line

The 20% transfer bonus from Chase Ultimate Rewards to Air France-KLM Flying Blue represents a solid opportunity to maximize value for SkyTeam alliance redemptions, particularly for business class flights to Europe. With the bonus running through September 30, 2025, you have a few weeks to consider your options and make a decision.

The optimal strategy depends on your specific travel plans and points portfolio. If you have immediate redemption needs on routes served by Air France, KLM, or their partners, this bonus can provide excellent value. However, if you value the flexibility of Chase points or have better uses for them with other transfer partners like World of Hyatt, you might want to be more selective about how many points you transfer.

As always with points transfers, the key is to have a specific redemption strategy in mind rather than transferring speculatively, especially given Flying Blue’s 24-month inactivity expiration policy.

Whether you decide to take advantage of this promotion or not, it’s a good reminder of the value that transfer bonuses can provide in maximizing your points and miles strategy.

Frequently Asked Questions

How long do transfers from Chase to Flying Blue take?

Transfers from Chase Ultimate Rewards to Air France-KLM Flying Blue typically process instantly or within a few minutes. However, you may need to log out and log back into your Flying Blue account to see the miles appear. This quick transfer time is advantageous when you find award availability and want to book immediately before it disappears.

Do Flying Blue miles expire?

Yes, Flying Blue miles expire after 24 months of inactivity in your account. Importantly, transferring points into your Flying Blue account does not reset the expiration clock for miles you already have. To extend the validity of existing miles, you need to either fly on Air France, KLM, or a partner airline, or earn miles through a Flying Blue co-branded credit card. This expiration policy is something to carefully consider before making a speculative transfer.

What are Flying Blue Promo Rewards?

Flying Blue Promo Rewards are monthly promotions that offer discounted award tickets on select routes, typically with savings of 25% to 50% off the standard award rates. These promotions are announced at the beginning of each month and are valid for travel during specific periods. By combining a Promo Reward with this 20% transfer bonus, you can achieve exceptional value for your Chase points. For example, a business class flight to Europe that’s discounted to 45,000 miles would require just 37,500 Chase points with the transfer bonus.

What other programs partner with Flying Blue for point transfers?

Flying Blue is one of the few airline programs that partners with all major transferable points currencies. You can transfer points to Flying Blue from American Express Membership Rewards, Capital One Miles, Citi ThankYou Points, and Chase Ultimate Rewards—all at a 1:1 ratio (before any bonuses). This wide availability of transfer options means you might want to save your Chase points for exclusive partners like World of Hyatt and use another currency for Flying Blue transfers, depending on your points portfolio and redemption goals.

Are there fuel surcharges on Flying Blue award tickets?

Yes, Flying Blue does impose carrier-imposed surcharges (often called fuel surcharges) on many award tickets. These can range from approximately $100-300+ for transatlantic flights, depending on the route, airline, and cabin class. Surcharges are typically higher for premium cabins and on Air France and KLM’s own flights. Some partner airlines, like Delta for domestic US flights, have lower or no surcharges. These additional costs should be factored into your calculation when determining whether a Flying Blue redemption represents good value.

What credit cards earn Chase Ultimate Rewards points?

Several Chase credit cards earn Ultimate Rewards points that can be transferred to Flying Blue. The primary cards include the Chase Sapphire Reserve^®, Chase Sapphire Preferred^® Card, and Ink Business Preferred^® Credit Card. Other cards like the Chase Freedom Flex℠, Chase Freedom Unlimited^®, and Ink Business Cash^® Credit Card earn points that can be combined with the premium cards mentioned above and then transferred to partners. This flexibility in earning and pooling points across multiple cards is one of the strengths of the Chase Ultimate Rewards ecosystem.
