Flying Blue Cost Per Mile (CPM) Explained
Every miles offer looks tempting until you ask the one question that settles it. What did you actually pay for each mile? That single number decides whether a purchase, transfer, or subscription is a smart move or a quiet loss. Most Flying Blue members never run it, so they overpay without knowing. This guide shows you exactly how to work it out, what a good rate looks like, and how to compare any deal before you commit.
Definition
Cost Per Mile (CPM) measures what you paid to acquire each Flying Blue mile. Calculate it as: Total Cost ÷ miles Received. A lower CPM is better. SkyStatus uses €0.012 as a practical benchmark: see how we estimate mile value. Above €0.015 usually only works with a clearly high-value redemption.
The CPM Formula
📘 Example
You buy 10,000 miles for €200.
CPM = €200 ÷ 10,000 = €0.02 per mile
This is above the €0.012 benchmark, so you need a redemption worth at least €0.02/mile to break even.
CPM Benchmarks
SkyStatus uses the following thresholds based on typical redemption values:
| CPM Range | Verdict | When It Makes Sense |
|---|---|---|
| Under €0.008 | 🌟 Excellent | Transfer bonuses, credit card earning on spend you would make anyway |
| €0.008 to 0.012 | ✅ Good | Standard transfers, flight earning, some promotional purchases |
| €0.012 to 0.015 | ⚠️ Fair | Subscribe to Miles, topping off for a specific redemption |
| €0.015 to 0.02 | ⚠️ Marginal | Only for high-value Business Class redemptions |
| Above €0.02 | ❌ Poor | Almost never worth it; consider paying cash instead |
CPM by Acquisition Method
| Method | Typical CPM | Notes |
|---|---|---|
| Transfer partners (with bonus) | €0.006 to 0.008 | ✅ Best option when 25%+ bonus available |
| Transfer partners (standard) | €0.008 to 0.01 | ✅ Excellent if you earn points on regular spending |
| Flying (implicit cost) | ~€0.01 | ✅ Part of your ticket cost; not incremental spend |
| Subscribe to Miles | €0.011 | ⚠️ Best for small top-ups; cancellable |
| Promo purchase (80% bonus) | €0.016 | ⚠️ Only for specific high-value redemptions |
| Promo purchase (45% discount) | €0.016 | ⚠️ Similar to bonus promos |
| Standard purchase | €0.028 | ❌ Almost never worth it |
Transfer Partners: The Best Value
The most cost-effective way to acquire Flying Blue miles is through credit card transfer partners. If you earn points on spending you would do anyway, your effective CPM approaches zero.
Official list of partners and conversion options: Flying Blue partner conversions.
Flying Blue transfer partners
- American Express Membership Rewards
- Chase Ultimate Rewards
- Citi ThankYou Points
- Capital One miles
- Bilt Rewards
- Wells Fargo Rewards
Transfer bonuses of 20 to 30% happen several times per year. A 25% bonus means 100,000 credit card points become 125,000 Flying Blue miles. Ratios may vary by partner and region.
📊 Transfer Bonus Example
You earn 50,000 Amex points on €25,000 credit card spend (2x earning rate).
Transfer during 25% bonus: 50,000 → 62,500 Flying Blue miles.
If you value the Amex points at €0.01 each: CPM = €500 ÷ 62,500 = €0.008/mile
This is excellent value, well below the €0.012 benchmark.
Subscribe to Miles
Flying Blue offers a monthly subscription service called "Subscribe to Miles" where you pay a fixed monthly fee for a set number of miles.
Official overview: Introducing Subscribe to Miles. Manage subscription: Subscribe to Miles portal.
| Package | Miles per Month | Price (USD) | CPM (USD) | CPM (EUR approx.) |
|---|---|---|---|---|
| Starter | 2,000 | $34.20 | $0.0171 | €0.014 |
| Smart | 5,000 | $79 | $0.0158 | €0.013 |
| Advanced | 10,000 | $146 | $0.0146 | €0.012 |
| Complete | 17,000 | $227.80 | $0.0134 | €0.011 |
Subscribe to Miles: Key Details
- Cancellation and refund rules depend on your checkout terms and country
- Miles validity is governed by the Flying Blue programme terms
- Posting timing can vary after payment
- Plan changes may be restricted depending on subscription terms
- Miles do NOT count toward XP or status
The Complete package at $0.0134 USD (approximately €0.011) is close to typical redemption values of €0.012. This makes it useful for topping off your balance for a specific redemption, but not for speculative accumulation.
Promotional Purchases
Flying Blue runs promotional purchase offers several times per year, typically offering 50 to 100% bonus miles or 35 to 45% discounts.
| Promotion Type | Effective CPM (USD) | Effective CPM (EUR) | Frequency |
|---|---|---|---|
| 100% bonus (best ever) | 1.53¢ | €0.0142 | Rare, last seen 2022 |
| 80% bonus (current Dec 2025) | 1.69¢ | €0.0157 | Several times per year |
| 45% discount | 1.68¢ | €0.0156 | Several times per year |
| 50% bonus | 2.03¢ | €0.0189 | Common |
| Standard (no promo) | 3.05¢ | €0.0284 | Always available |
CPM vs Value Per Mile
Do not confuse these two metrics. They measure opposite sides of the equation.
- CPM (Cost Per Mile): What you PAID to acquire the mile (lower is better)
- Value Per Mile: What the mile is WORTH when you redeem it (higher is better)
Your goal is simple: Low CPM + High Value Per Mile = Profit. The spread between them determines whether you come out ahead or behind.
📊 Profit Example
Acquire miles via transfer bonus at €0.008 CPM
Redeem for Business Class at €0.025 value
Profit = €0.017 per mile (3.1x return on "investment")
📊 Loss Example
Buy miles at €0.016 CPM (80% bonus promo)
Redeem for short-haul Economy at €0.008 value
Loss = €0.008 per mile (50% loss)
Weighted Average CPM
If you acquire miles from multiple sources, calculate your weighted average to understand your true cost basis:
📊 Portfolio Example
Your mile sources this year:
- Transfer (25% bonus): 62,500 miles from 50,000 points valued at €500
- Subscribe to Miles (1 month): 17,000 miles for €187
- Flying: 25,000 miles (implicit cost ~€250 of ticket price)
Weighted CPM = €962 ÷ 104,500 = €0.0092/mile
This is excellent! Below the €0.012 benchmark, meaning most redemptions are profitable.
Practical Application
Here is how to use CPM in your decision-making:
- Track your acquisition costs using SkyStatus or a spreadsheet
- Before any purchase, calculate the CPM and compare to €0.012
- Before any redemption, calculate the value per mile
- Only proceed if redemption value exceeds acquisition cost
- For XP runs, remember that miles earned from flying have an implicit CPM that is part of the ticket price you already paid

FAQ
What is a good cost per mile for Flying Blue?
A good CPM is under €0.012 (1.2 cents). SkyStatus uses this as a practical benchmark based on typical redemption values. Below €0.01 is excellent. Above €0.015 is marginal, and above €0.02 is poor value unless you have a specific high-value redemption planned.
What is the cheapest way to acquire Flying Blue miles?
The cheapest methods are: (1) Transfer partners during bonus promotions (effectively free if you earn credit card points anyway), (2) Subscribe to Miles at around 1.34 cents USD per mile for the Complete tier, (3) Promo purchases with 80%+ bonus at around 1.69 cents per mile. Standard purchases at 3+ cents are rarely worth it.
How do I calculate cost per mile?
Divide the total cost by the miles received. For example: €200 spent on 15,000 miles = €200 ÷ 15,000 = €0.0133 per mile. Compare this to typical redemption values (€0.01-0.02) to determine if it was a good deal.
