Citi just lit up a 20% transfer bonus from ThankYou Points to Flying Blue (Air France KLM): live Jul 19 – Aug 22, 2026, initiated via thankyou.com transfer page.
The 20% is added on top of the base 1:1 TY→FB ratio, and stacks with FB’s own monthly Promotions (XP purchase tiers, targeted X-redemptions, etc.). Window is short — 5 weeks only.

Key Dates & Rules
- Transfer window: Jul 19 – Aug 22, 2026 (inclusive); must be initiated within this window on thankyou.com
- Bonus: +20% on top of base transfer (e.g. 10k TY → 10k FB + 2k bonus FB)
- Base ratio: Citi TY → FB is 1:1 flat; these periodic bonuses are the only time it lifts
- Posting: Citi→FB typically T+2 to T+3 business days; bonus posts same time or slightly after. Don’t leave the last transfer for Aug 22.
- Min/Max: Citi TY→FB single transfer usually starts at 10k TY min (check thankyou.com real-time); Citi side didn’t publish a cap for this round, but FB side has its own daily/monthly inbound limits per FB program rules
Who This Is For
US East Coast / China-EU / Africa flyers
Flying Blue is the value play for EU via CDG, West Africa via ABJ/ACC, and French Caribbean. Delta JFK/BOS–CDG/AMS often codeshares AF/KL metal, but DL awards price high + taxes; booking AF/KL on FB XP with low taxes is the common workaround. If you sit on 5-figure TY and have an AF/KL trip in ’26, this 20% pulls ahead of the usual 1:1.
People stacking FB monthly Promotions
FB drops a rotating Promo almost every month — targeted X-redemptions, hotel/car XP bonuses, purchase tiers. TY transfers land as FB mileage principal, so they participate in whatever Promo is live that month. “TY 20% transfer + FB monthly Promo” are two independent pipes.
Note on TY source cards: ThankYou Preferred / Premier / Prestige / Custom Cash have different transfer rights. Premier/Prestige usually full-transfer; no-fee cards (Preferred) may be restricted unless you “pool” under a higher-tier TY account. Log in thankyou.com first, check if FB shows in your “Transfer Points” and what the per-transfer floor is.
How to Do It
- Log into thankyou.com → “Transfer Points” → Flying Blue (Air France KLM)
- Confirm your Flying Blue number is linked in TY (First/Last Name spelling must match FB account exactly, otherwise miles land in someone else’s lap)
- Enter amount (watch per-transfer minimum; do one larger lump rather than several small ones so the 20% bonus isn’t fragmented)
- Posting T+2-3 biz days; bonus +20% same batch or 1-2 days after
Other Citi TY Moves This Window
- Citi TY other partner bonuses: Jul 2026 Citi often runs parallel 20-30% on AA, Avianca LifeMiles, Singapore KrisFlyer — compare which partner fits your next trip; FB this round skews EU/Africa.
- FB dynamic pricing: intra-Europe short-hauls 4.5k-7.5k XP common; TATL economy promo 25k-30k XP r/t pops seasonally. 20% bonus effectively knocks ~16.7% off dynamic pricing if you’re promotion-hunting.
- DL联营绕路 (US East): JFK/BOS–CDG/AMS on DL codeshare AF/KL, but DL awards price high; TY→FB→AF/KL metal + low taxes is the known micro-move for US East flyers.
Where People Trip
- Short window: Jul 19 open, Aug 22 close — 5 weeks tops. Citi→FB T+2/3 weekdays + possible 1-2 day lag on bonus. Nothing new after Aug 18.
- Name mismatch: TY side binding FB number — First/Last must align exactly with FB profile, otherwise unrecoverable.
- FB miles 24-month expiry: any earning/redemption resets the 24-month clock. Check if old FB balance is near expiry before pulling this transfer — don’t let the fresh 20% land then sit stale.
