Surprising fact: a 20% transfer boost can turn 50,000 Ultimate Rewards into 60,000 Flying Blue miles, cutting the points needed for many premium awards by a large margin.
We’ll walk you through this limited-time offer that runs through September 30, 2025, at 11:59 pm ET. This promo stretches your ultimate rewards points into more miles and opens high-value redemption routes for business and economy travel.

How to Maximize the 20% Chase Ultimate Rewards Flying Blue Transfer Bonus
Start by verifying seat availability, then calculate the necessary moves to ensure you only move what you need.
When it makes sense
Confirm the award space first. Search Air France, KLM, Delta, or partner inventories before any move. If saver seats are visible, the boost cuts the ultimate rewards points you need.
Value math
Compare a one-way AF/KLM business at roughly 60k miles (about 50k chase points after bonus) with a portal booking at up to 2 cents per point. When cash fares spike, transferred miles often deliver superior value. Use cents-per-point as a quick rule of thumb.
Timing and partners check
Keep most points in Chase and top off only what you need, plus a small buffer for fees. Watch Promo Rewards—economy can drop to 18,750 and business to 45k miles. Also, compare Iberia, Aeroplan, and Virgin Atlantic; each partner offers distinct ways to stretch value.
- Tip: search one-way legs, be flexible on dates and gateways, and set alerts for Promo Rewards.
Best Flying Blue sweet spots to target with your bonus miles
A few clear sweet spots will stretch your miles far for both short hops and long hauls.
Short domestic hops: Domestic Delta awards can start at 5,000 flying blue miles one-way with the promo uplift, which equals roughly 4,200 chase points per flight. These redemptions are ideal for quick weekend trips or last‑minute positioning.
Transatlantic and Promo Rewards
Air France/KLM saver levels price transatlantic awards from about 25,000 miles in economy and 60,000 in business class. Stacked Promo Rewards can cut rates further — economy from 18,750 and business from 45,000 on select routes.
- China Airlines business class to Taipei: ~62,500 miles one-way (a standout partner redemption).
- Free stopover available in Paris or Amsterdam — call 800-375-8723 to book a ticket.
- Search gateways (JFK, BOS, LAX, SFO, SEA, ATL, MIA, IAD) and hubs (CDG, AMS) for saver award space.
Strategy: lock awards first, then move only the needed points. Watch fees on Air France/KLM awards and compare portal pricing when cash fares are low.
Step-by-step: transferring Chase Ultimate Rewards points to Flying Blue.
Set up your Flying Blue profile now and check the exact award inventory you plan to book.
Prep work
Create a Flying Blue account and confirm your name and membership number match your Chase profile.
Search award space on Air France, KLM, or partner sites and note fees for your itinerary.
The transfer flow
Log in to your Chase account, open Ultimate Rewards, choose Travel, then select “Transfer points to partners.”
Pick Air France/KLM Flying Blue, enter the membership number, and choose the number of points in 1,000 increments.
Most transfers post instantly, which lets us complete the booking in the same session.
Irreversible transfers and safeguards
Double-check totals and passenger details before you submit. Once sent, a points transfer is final.
“Verify seats and save screenshots; it can save hours if availability drops while you transfer.”
- Keep both Chase and Flying Blue pages open during the process.
- Screenshot flight details, fare class, and remaining seats as proof.
- If pooling points with a household member, call the number on your card once to enable transfers.
| Step | Action | Why it matters |
|---|---|---|
| Prep | Create account, match names | Avoid delays or rejected transfers |
| Portal flow | Ultimate Rewards → Travel → Transfer to partners | Exact route for a successful points transfer |
| Increments | 1,000-point blocks; usually instant | Enables same-session booking |
| Troubleshoot | Log out/in, clear cache, wait a few minutes | Fix occasional posting delays |
Timing tip: transfer the most critical long-haul leg first, then add connections. Keep a backup date or route in case award space vanishes during the process.
Smart stacking, expiration rules, and pitfalls to avoid
Miles expiration and what resets the clock
Flying Blue miles expire after 24 months of inactivity. Simple account balances move won’t refresh flown miles.
Qualifying activity resets the timer: flying on Air France, KLM, or a partner, or spending on a Flying Blue co-branded card.
Stacking options and practical strategies
Pair the 20% conversion with monthly Promo Rewards for steep discounts. Use short positioning flights to reach better gateways.
Consider mixed-class itineraries: lock the long-haul business segment first, then add cheaper economy legs.
Common mistakes and alternative plays
Never transfer points without confirmed award space. Factor in taxes, surcharges, and mixed-fee legs before committing.
“Hold a small reserve of ultimate rewards points in your Chase account for last-minute top-offs.”
Look at Aeroplan for Star Alliance access, Iberia for U.S.–Madrid nonstop deals, Virgin Atlantic for niche partner redemptions, and Hyatt for hotel value via points transfers.
| Issue | Fix | Why it matters |
|---|---|---|
| Expiration risk | Earn or redeem within 24 months | Prevents balance loss |
| Transferring blind | Confirm the award space first | Avoid stranded points |
| High fees | Compare the portal and other partners | Choose the best real cost |
| Over-transferring | Keep a small Chase reserve | Flexibility for last-minute needs |
Conclusion
When award space lines up, a careful transfer can shrink the cost of European trips dramatically.
We recommend confirming awards first, then moving only the exact points you need. This approach protects your balances and uses instant posting to lock seats.
Headline values: domestic Delta routes can start near 5,000 miles, Air France and KLM economy often from 25k and business around 60k, with Promo Rewards dipping select routes lower.
Triple-check account names, taxes, fees, and have alternate dates or gateways ready. Keep a small cushion of chase points for quick top-ups and monitor monthly Promo Rewards for new deals.
Next step: search award space now, compare portal pricing, then move points only when the math and availability align. Act before Sep 30, 2025, at 11:59 pm ET for this uplift and plan redemptions within 24 months to avoid expiration.
