100K Flying Blue miles: the XP flips the math on a 5/24 slot.

Bank of America cardholders can score a $175 statement credit by spending $1,500 within 90 days through the close-card flow in the app or online chat. That's an 11.67% return before normal earnings, which on a Customized Cash card with the 3% online category pushes it to 14.67%. BofA appears to allow one retention offer per cardholder at a time, so target your most valuable card first. The process gives clear warnings before closing, so there's low risk of accidental cancellation.

Turkish Airlines is running a gift-miles promo from July 27 through August 7, 2026, where sending 1,000 miles to another member costs $30 and earns you 1,000 bonus miles back – effectively buying miles at 3 cents each. That’s the price of a mediocre cash ticket, not a smart mileage play. For a program whose best redemptions can clear 2 cpp, paying 3 cpp upfront leaves no margin. The 250,000 annual receiving cap limits the upside for anyone hoping to flood an account, and the bonus miles don’t post until a week after the campaign ends. This is noise, not signal.
