What happened
Turkish Airlines is offering a 100% bonus on Miles&Smiles purchases of 250,001 to 500,000 miles in one transaction from September 29 through October 15, 2026. Orders of 100,001 to 250,000 miles earn 50% extra. Orders of 50,000 to 100,000 miles earn 25% extra. Separate purchases cannot be combined to reach a higher bonus.
Purchases are made on the Turkish Airlines website or app after a Miles&Smiles login. Extra miles are missing from the purchase screen and post within 7 days after the campaign ends. A 300,000-mile buy plus 300,000 bonus miles is priced at $9,000, or 1.5 U.S. cents per mile. Bought miles and bonus miles do not count as status miles and are non-refundable. Members may purchase at most 500,000 miles in a calendar year during the campaign.
Buy 250,001 miles or more in a single order by October 15 only against a Turkish Airlines award already planned.
