How long is the American Express 20% Flying Blue transfer bonus available?

The 20% transfer bonus is available through October 31, 2025, ending at 11:59 PM Mountain Time. You must complete your transfers by this deadline to receive the bonus miles.

How many Flying Blue miles will I receive with the 20% bonus?

With the 20% bonus, you'll receive 1,200 Flying Blue miles for every 1,000 American Express Membership Rewards points transferred. The bonus is automatically applied when you make the transfer, so you'll see the total miles before confirming.

Do I need to be a Flying Blue member before transferring points?

Yes, you must be enrolled in the Air France-KLM Flying Blue program before making any transfers. Registration is free and can be completed quickly on the Flying Blue website. You'll need your Flying Blue membership number when initiating transfers from American Express.

How quickly do transfers from American Express to Flying Blue process?

Transfers are typically instant, though American Express recommends allowing up to 48 hours for completion. Most transfers appear in your Flying Blue account within minutes of confirmation.

What are the best ways to use Flying Blue miles?

Top redemptions include Air France/KLM business class to Europe (60,000 miles = 50,000 Amex points with bonus), short-haul Delta flights (5,000 miles one-way), and KLM business class to Africa (115,000 miles = 96,000 Amex points with bonus). Monthly Promo Rewards offer additional discounts.

Do Flying Blue miles expire?

Flying Blue miles expire after 24 months of account inactivity. Transferring points from American Express doesn't count as qualifying activity, so you'll need to fly on Air France, KLM, or SkyTeam partners, or use a Flying Blue credit card to keep miles active.

Can I transfer points back to American Express if I don't use them?

No, transfers from American Express Membership Rewards to Flying Blue are permanent and cannot be reversed. Only transfer points if you have realistic plans to use the miles within Flying Blue's 24-month expiration period.

How often does American Express offer Flying Blue transfer bonuses?

Based on historical data, American Express typically offers Flying Blue transfer bonuses about once per year, though timing and bonus percentages vary. The current offer is the first in over a calendar year, making it particularly valuable.

Are there limits on how much I can transfer during the bonus period?

You can take advantage of the bonus multiple times throughout October. Each transfer requires a minimum of 1,000 points and allows up to 999,000 points per transaction. There's no overall limit on total transfers during the promotion period.

Should I make a speculative transfer with this bonus?

The 20% bonus makes speculative transfers more attractive, especially given Flying Blue's competitive award pricing and 24-month expiration period. However, only transfer if you have realistic travel plans within two years, as transfers cannot be reversed and don't count as qualifying activity to prevent expiration.
