Flying Blue miles expiration: how to prevent it

When do your miles expire?
According to the official Flying Blue terms and conditions (Section 1.2.9), your miles expire after 24 months without a qualifying activity. The clock starts running from the moment of your last activity that extends your miles.
"Inactivity" means that during those 24 months you have not performed a single activity considered "extending" by Flying Blue. This does not include logging into your account or checking your balance, but specifically refers to earning miles through qualifying channels.
How to check your expiration date
- Log in to flyingblue.com
- Go to your miles balance (dashboard or "My account")
- Look for the "miles valid until" date
- If no date is shown, you may have elite status (in which case your miles do not expire)
What changed on May 4, 2026: unified miles validity
This is the most important concept that many sources miss. Flying Blue's terms and conditions distinguish between two types of activities that extend your miles. The difference has major implications for how well your miles are protected.
The new rule (from May 4, 2026)
Every eligible earning activity now extends your entire miles balance by 24 months. Whether you fly, use your Amex card, book a hotel through a Flying Blue partner, shop via the Shopping Portal, or earn miles through Subscribe to Miles - it all resets the clock for your complete balance. Your existing miles are merged with the most favorable expiration date at implementation.
All activities that extend your miles (from May 4, 2026)
- Flying on a qualifying flight (AF, KLM, SkyTeam partners)
- Purchases with the co-branded credit card (Flying Blue American Express)
- Hotel bookings through Flying Blue partners
- Car rentals through Flying Blue partners
- Shopping Portal purchases
- Subscribe to Miles subscription earnings
- Partner transfers (Amex Membership Rewards, etc.)
The old rule (before May 4, 2026)
Before the change, Flying Blue distinguished between two types of activities:
- "Overall extending activities" (flights and Amex purchases) extended your entire balance
- "Partial extending activities" (hotels, shopping, subscriptions, partner transfers) only extended miles earned after your last overall activity
This meant you could have multiple expiration dates for different batches of miles. The new rule eliminates this complexity: one balance, one expiration date, extended by any eligible earning activity.
| Activity type | Examples | Extends your miles? (from May 4, 2026) |
|---|---|---|
| Eligible earning activity | Flights, Amex card purchases, hotels, car rentals, Shopping Portal, Subscribe to Miles, partner transfers | Yes - extends your entire balance by 24 months |
| No extension | Buying miles, spending/redeeming miles, logging in | No |
Why this change matters: a practical example
Old rule: You had 80,000 miles from flights (18 months ago) and 5,000 miles from the Shopping Portal (3 months ago). Under the old rules, the shopping activity only protected the 5,000 new miles, NOT your 80,000 flight miles. Those were still set to expire in 6 months.
New rule (from May 4, 2026): That same shopping activity now extends your entire balance of 85,000 miles by 24 months. No more worrying about which miles are protected and which are not.

The cheapest ways to prevent expiration
If your miles are about to expire, you want to choose the cheapest option that protects your entire balance. Below I compare the options by cost, sorted from cheapest to most expensive.
1. Shopping Portal purchase (free)
The Flying Blue Shopping Portal offers miles on purchases at hundreds of online stores. If you are buying something anyway, this is free. From May 4, 2026, this extends your entire miles balance by 24 months.
2. Flying Blue Amex Gold Card (EUR 16.50/month)
The Flying Blue American Express Gold Card is the cheapest "always-on insurance" against miles expiration. Every purchase you make with the card earns miles and extends your entire miles balance by 24 months.
- Cost: EUR 16.50/month (EUR 198/year)
- Extends: Your entire miles balance by 24 months
- Bonus: 1 mile per EUR spent + 30 XP per year
- Advantage: Every card purchase automatically extends your entire balance
3. A cheap flight (EUR 50-100)
A single Economy flight within Europe extends your entire miles balance. You can find a cheap route for EUR 50-100 one-way. This protects your entire balance, but it is a one-time action. You will need to do it again in 24 months.
4. Subscribe to Miles (from EUR 12/month)
Subscribe to Miles gives you a fixed number of miles each month. From May 4, 2026, it extends your entire balance just like any other earning activity. At from EUR 12/month it is a solid low-cost option for keeping your miles alive.
| Option | Cost/month | Type | Extends all miles? (from May 4) |
|---|---|---|---|
| Shopping Portal | Free (with an existing purchase) | Extends all | No |
| Amex Gold Card | EUR 16.50 | Extends all | Yes (all activities do from May 4) |
| Cheap flight | One-time EUR 50-100 | Overall | Yes |
| Subscribe to Miles | From EUR 12 | Extends all | No |
| Amex Platinum Card | EUR 55 | Overall | Yes |
Best choice for most people
The Flying Blue Amex Gold Card remains the easiest way to keep your miles alive. Every purchase (groceries, fuel, online shopping) earns miles and automatically extends your entire balance. From May 4, 2026, even a hotel booking or Shopping Portal purchase does the same - but the Amex requires zero extra effort. At EUR 16.50/month, the card pays for itself if you have more than ~16,500 miles (based on a miles value of EUR 0.012).
Elite status: exemption from expiration
Members with elite status (Silver, Gold, Platinum or Ultimate) are fully exempt from miles expiration. As long as you maintain your status, your miles do not expire, regardless of how long it has been since you last earned miles.
Keep in mind that Silver status is achievable from just 100 XP. With the Flying Blue Amex Gold Card you earn 30 XP per year without flying. Two flights with a connection in Business or Premium Economy may be enough to earn the rest. Once you have Silver, your miles are safe for an entire year.
The Flying Blue Family trick
Flying Blue Family offers a smart way to prevent miles expiration for your entire household. Within a Family account, members share the same activity clock. If one family member performs an extending activity, it can protect the miles of the entire family.
How it works
Situation: Your partner flies regularly for work, but you do not. You have 50,000 miles that are about to expire.
Solution: Add your partner to Flying Blue Family. Every time your partner earns miles (through flights, card purchases, or any other eligible activity), the miles of the entire family are protected.
Alternative: A Family member who earns miles regularly (via Amex, flights, shopping, or subscription) protects the miles of the entire household.
Recovering expired miles: is it possible?
The short answer: there is no standard mechanism to recover expired miles. Once miles have expired, they are permanently lost according to the official terms and conditions.
There are occasional reports of members who received a "goodwill gesture" through customer service, where a small portion of their expired miles was restored. However, this is:
- Not guaranteed and entirely at the discretion of Flying Blue
- Usually only for members with a long history in the program
- Limited to a relatively small number of miles
- Not an official policy, so you cannot count on it
Prevention is the only reliable approach
Do not count on recovering expired miles. Make sure you perform an extending activity in time. The cost of prevention (e.g. EUR 16.50/month for the Amex) is almost always lower than the value of lost miles.
Calculation example: prevention vs loss
Situation: You have 100,000 miles that are about to expire.
Value: 100,000 x EUR 0.012 = EUR 1,200 in value
Prevention cost: EUR 16.50/month for the Amex Gold = EUR 198/year
Conclusion: Spending EUR 198 to protect EUR 1,200 is a 6x return.
