Citi Transfer Bonus: 40% to Turkish Miles&Smiles Through Aug 31

Citi ThankYou is running a 40% transfer bonus to Turkish Miles&Smiles through August 31, and Turkish is one of the most rewarding Star Alliance programs to hold points in.

• The rate: 1,000 Citi ThankYou points become 1,400 Turkish miles.
• Why Turkish: strong Star Alliance sweet spots, including cheap United domestic flights and US-to-Europe awards.
• Two catches: the bonus is capped at 50,000 bonus miles (transfer about 125,000 to max it), and the bonus posts retroactively after the promo ends, not instantly.
• The deadline is early: it ends 11:59pm Turkiye time on August 31, a few hours before US midnight.
• Transfer only with an award in mind since Turkish miles can be tricky to use.
• Ends August 31, 2026 (Turkiye time).
