Air France-KLM's Flying Blue has quietly expanded its mileage subscription service, and the maths now beats anything the programme offers through its regular buying promotions. Subscribe to Miles, launched in late 2024, lets members purchase a fixed monthly batch of miles at a locked-in price. A new top tier doubles what was previously available, and at the best rates you're paying about 1.34 cents per mile.
There are now five tiers. Starter gets you 2,000 miles a month for $34.20 (1.71 cents each), Smart is 5,000 for $79.00, Advanced is 10,000 for $146.00, Complete is 17,000 for $227.80, and the new Complete+ delivers 30,000 miles monthly for $402.00. Taxes and fees are included in those prices, and the two largest tiers work out to the same 1.34 cents per mile. For comparison, Flying Blue's periodic outright purchase bonuses top out at around 80% extra, which works out to roughly 1.69 cents per mile. The subscription undercuts that — if you can wait.
The terms are relatively forgiving. You commit to a minimum of three months, then cancel whenever you like through your account. Miles land within 72 hours of each monthly charge, an active subscription keeps your balance from expiring (Flying Blue miles otherwise die after 24 months of inactivity), and you can pull out penalty-free within 14 business days of a purchase. Two catches: subscription miles don't count toward elite status, and payments run through points.com, so your credit card won't treat them as an airfare spend — no airline bonus categories here.
Who should bother? Honestly, not most people. If you regularly earn Flying Blue miles by transferring points from flexible currencies like Amex or Citi during transfer bonuses, that will almost always be cheaper. And nobody should buy miles speculatively without a specific redemption in mind and the numbers crunched.
But there's a genuine use case: you've found award space in Air France or KLM business class — Flying Blue is one of the better programmes for long-haul premium redemptions, especially if you hold elite status, which unlocks better availability and terms — and you're short on miles. Subscribing for three to six months at the top tiers could top off your account more cheaply than a standard promotion, provided you plan ahead, since miles trickle in monthly rather than arriving in one lump.
The 14-day withdrawal right also gives you a safety net if your plans change early on. Treat it as a tool, not a habit, and it can shave real money off a business class booking.
