Turkish Airlines is running a buy-miles promotion for Miles&Smiles members: the bonus goes up to 100%, and purchases count from September 29 through October 15, 2026.
How the bonus tiers work
The bonus depends on how many miles you buy in a single transaction:
- 50,000–100,000 miles: 25% bonus
- 100,001–250,000 miles: 50% bonus
- 250,001–500,000 miles: 100% bonus
Each transaction is counted on its own, so two purchases of 150,000 miles will not add up to the top tier.
What it costs
Buying 300,000 miles costs $9,000, or 3 cents per mile. With the 100% bonus you get 600,000 miles in total, which brings the effective price down to 1.5 cents per mile.
Fine print
The bonus miles are not shown at checkout and arrive in your account within seven days of the purchase. Neither the purchased nor the bonus miles count as Status Miles.
