Quick Answer
The Citi to Turkish Airlines transfer bonus August 2026 offer gives a 40% bonus on Citi ThankYou points transferred to Turkish Miles&Smiles, with the campaign running through August 31, 2026. The catch is structural, not a glitch: Turkish credits the base miles within the normal transfer window, but the 40% bonus miles post only after the campaign closes, meaning the earliest you can expect them is September 1, 2026. If you need every mile in hand to book a specific award seat this week, transfer only what you can book with the base miles and treat the bonus as a later top-up.
Key Takeaways
The promotion is a 40% bonus, run by Turkish Miles&Smiles (not Citi), and it ends August 31, 2026.
Premium Citi cardholders (Strata Elite, Strata Premier, Prestige, AT&T Access More) effectively get 1,400 Turkish miles per 1,000 ThankYou points.
Bonus miles are credited after the campaign period ends, so plan on early-to-mid September for posting, not instant availability.
The bonus is capped at 50,000 bonus miles, which corresponds to roughly 125,000 ThankYou points transferred.
Base miles typically post fast (often same-day to a couple of business days), so the delay applies only to the bonus portion.
The strongest Miles&Smiles sweet spots remain partner Star Alliance awards, especially United domestic economy and long-haul partner business class.

Transfers are irreversible. Confirm award space before moving points, because Turkish’s dynamic-ish partner pricing and phone-only bookings add friction.
Skip this bonus if you have no concrete redemption in mind. A 40% boost on miles you never use is still zero cents per point.
What Is the Citi to Turkish Airlines Transfer Bonus?
It is a Turkish Miles&Smiles promotion that adds 40% extra miles when you convert Citi ThankYou points to Miles&Smiles during the campaign window ending August 31, 2026. Turkish sponsors and administers the offer, which is why the terms, the cap, and the crediting schedule follow Turkish’s rules rather than Citi’s.
Two details separate this from a typical Amex or Chase bonus:
The airline runs it. Citi’s transfer page may not advertise it prominently. Registration or campaign terms live on the Turkish side.
Bonus miles are batched. Turkish credits promotional miles after the campaign closes, not at the moment of transfer.
Bonus miles from this promotion are award miles only. They do not count toward Elite or Elite Plus status, and transferred miles never earn status miles in Miles&Smiles.
Before moving anything, it helps to know where Turkish sits among your options. Our Turkish Airlines Miles&Smiles transfer partners overview covers which currencies feed the program and at what ratios.
What the Citi to Turkish Airlines Transfer Bonus Actually Offers
The practical value depends entirely on which Citi card you hold, because the base transfer ratio is not identical across the ThankYou lineup.
Card groupEffective miles per 1,000 ThankYou pointsNotesCiti Strata Elite, Strata Premier, Citi Prestige, AT&T Access More1,4001,000 base + 400 bonus milesOther ThankYou cards (Double Cash, Custom Cash, Strata, ThankYou Preferred, most AT&T cards)~980 base, plus the 40% applied per Turkish’s termsWeaker starting ratio; confirm your card’s ratio in your Citi account before transferring
Two rules of thumb:
If you hold a premium ThankYou card, 1,400 miles per 1,000 points is a genuinely strong ratio for a Star Alliance program.
If you only hold cash-back-style ThankYou cards, the sub-1:1 base ratio eats much of the gain. Pool your points into a premium card account first if you have one on the same login.
How does the 40% transfer bonus work?
You transfer ThankYou points to your Miles&Smiles account during the campaign window; Turkish credits the base miles on its normal schedule and then adds 40% of that base amount as separate promotional miles after August 31, 2026.
Transfers are made from Citi’s ThankYou portal, in increments Citi sets (commonly 1,000 points, with a 1,000-point minimum).
Your name on the Citi account must match the Miles&Smiles account. Mismatches are the single most common cause of stuck transfers.
U.S.-issued Citi accounts are eligible; the Miles&Smiles account must be active and, ideally, at least a few days old.
Common mistake: transferring on August 31 and assuming the whole balance shows up in time to book a seat that expires from availability the next morning. It will not.
The Timing Trap: Why Your Bonus Miles Do Not Arrive With the Transfer
Turkish’s campaign terms state that promotional miles are credited after the campaign period ends. That is the direct cause of the “late” miles, it is written into the offer, not a processing error. The earliest realistic posting date for this promotion is September 1, 2026, and points blogs tracking the offer in early August 2026 read the terms the same way.
The base miles are the ones you can book with in August. The 40% is a September deposit. Plan the booking around that split.
Why are my transfer bonus miles delayed?
Because Turkish batches promotional credits at the end of the campaign rather than issuing them per transaction. Base miles and bonus miles travel on two different clocks.
Base miles: usually post quickly, often within the same business day and typically within about two business days.
Bonus miles: post after August 31, 2026, commonly within days to a few weeks of the campaign closing.
How long does it take to receive transfer bonus miles?
Expect base miles in roughly 0 to 2 business days and the 40% bonus at some point after September 1, 2026. Turkish does not publish a guaranteed hour-by-hour timeline, so treat any specific promise of “instant” bonus miles as inaccurate.
What happens if my bonus miles don’t post?
Give it a reasonable buffer after the campaign closes, then escalate with documentation. A practical sequence:
Wait until at least mid-September 2026 before treating it as a problem.
Screenshot your Citi transfer confirmations (date, points amount, destination account) before you need them.
Confirm the base miles posted to the correct Miles&Smiles number and that the name matches exactly.
Contact Miles&Smiles customer service in writing, referencing the Citi campaign and your transfer dates.
If Turkish denies the credit, ask Citi to confirm the transfer date and amount in writing as supporting evidence.
Edge case: transfers initiated late on August 31 that Turkish records as posting on September 1 may be treated as outside the campaign. If you want the bonus, transfer with a day or two of margin.
This is exactly why timing matters more than the headline percentage. Our guide on when transfer bonuses are actually worth chasing walks through the math of waiting versus acting.
Is the 40% Bonus Still Active in August 2026?
Yes, as of this writing, the 40% Citi-to-Turkish bonus is live and scheduled to end August 31, 2026. Because Turkish administers the campaign and posting rules can be updated, verify the percentage, the end date, the time zone the deadline follows, and the cap on the official Turkish campaign page before you transfer.
Things worth re-checking on the campaign page:
The exact cutoff time and time zone (deadlines that read “August 31” can effectively close hours earlier in U.S. time zones).
Whether registration is required.
Whether the cap is per account or per transfer.
What’s the Difference Between Transferring Now vs Waiting for the Bonus?
Transfer now if the bonus is live and you have a redemption in mind; there is no better version of this offer to wait for once the campaign is running. Waiting only makes sense if you have no booking target, because unused miles carry devaluation risk that no transfer bonus offsets.
Choose “transfer now” if:
You have found or confirmed award space and know the mileage price.
You hold a premium ThankYou card at the 1,400-per-1,000 ratio.
You can cover the base cost of the award with base miles alone, or your travel dates are far enough out that a September top-up is fine.
Choose “wait” if:
You have no specific route, cabin, or date in mind.
You would be transferring purely to speculate on future Star Alliance pricing.
Your card only earns the sub-1:1 base ratio and the redemption value is marginal.
Can I combine multiple transfer bonuses?
No. This is a single Turkish campaign, and promotional offers of this type are generally not stackable with other Turkish mileage campaigns on the same transfer. You also cannot combine it with a Citi-side promotion, because Citi is not running one here.
What you can do is diversify across currencies. If a different program is running a better offer for your specific route, compare first. Recent examples worth reviewing include the Citi ThankYou to Virgin Atlantic transfer bonus and the Citi to Flying Blue bonus analysis.
Turkish Miles and Smiles Sweet Spots Worth Targeting
Miles&Smiles earns its reputation on partner Star Alliance awards, not on Turkish’s own metal, where surcharges and availability are less friendly. The program historically prices partner awards off region-based tables that are cheaper than most Star Alliance competitors for the same seat.
Where the value concentrates:
United domestic economy on short and medium routes. Turkish has long been one of the cheapest ways to book U.S. domestic Star Alliance economy, which makes it useful for positioning flights.
Long-haul partner business class to Europe and Asia on carriers like ANA, EVA Air, Lufthansa (when saver space opens), Singapore, and Air Canada.
Intra-Asia and intra-Europe partner hops, which often price well below the operating carrier’s own program.
Where it disappoints:
Turkish-operated flights from Europe can carry meaningful fuel surcharges, cutting into value.
Award availability is the binding constraint. Turkish only sees what partners release into saver inventory, and Lufthansa first class is effectively off-limits.
Phone-only bookings for many partner itineraries, which slows everything down.
For a broader sense of which Citi partners deserve your points, see our comparison of Chase, Amex, Citi, and Capital One transfer partners.
How many Citi points do I need to make the transfer worth it?
Enough to complete an actual award, plus a small buffer. Transferring 8,000 points to collect 3,200 bonus miles is not useful if the award you want costs 45,000.
Decision rule:
Price the award first in Miles&Smiles.
Divide that mileage cost by 1.4 to get the ThankYou points needed (premium cards).
Transfer that amount, rounded up to the nearest 1,000, only if the award seat exists.
If the seat does not exist yet, transfer the smaller amount you are confident you will use.
Is there a limit to how many miles I can transfer with bonus?
The bonus is limited to 50,000 promotional miles, so the practical ceiling for bonus purposes is around 125,000 ThankYou points. There is no benefit to transferring more than that during this campaign unless you separately need the miles.
Booking Realities: Award Availability, Phone Agents, and Account Setup
Turkish is a high-value program with real operational friction. Setting up correctly before you transfer prevents most problems.
Pre-transfer checklist:
Open the Miles&Smiles account well before you transfer and verify the name matches your Citi profile exactly.
Search partner space on a reliable tool (United’s site and Aeroplan are common proxies for Star Alliance saver inventory), then cross-check on Turkish.
Note the flight numbers, dates, and cabin before calling.
Confirm the taxes and surcharges quoted, especially on Turkish-operated segments.
Only then transfer, and only the amount needed.
Things that trip people up:
Married segment logic can hide connections that would otherwise be bookable. Try alternative routings.
Phone agents vary widely. If one agent cannot see the space, a polite hang-up-and-call-back sometimes works.
Dynamic and changing pricing. Turkish has adjusted its charts before, and Star Alliance partners control the inventory. Prices seen last month are not guarantees.
Does Turkish Airlines devalue miles after transfer?
Turkish has revised award pricing and program rules in the past, as most airline programs have, so there is real devaluation risk in holding a large speculative Miles&Smiles balance. The safest approach is to transfer close to booking, not months ahead. If the award you want requires the September bonus miles, accept that you are carrying a few weeks of exposure.

What Are the Alternatives to Transferring to Turkish Airlines?
If Turkish’s phone bookings, surcharge exposure, or delayed bonus miles do not fit your plans, other transferable-points routes can reach the same Star Alliance seats or comparable premium cabins.
Star Alliance alternatives:
Air Canada Aeroplan, online booking, broad partner access, transparent pricing, but higher mileage costs on many routes.
Avianca LifeMiles, no fuel surcharges on most partners and frequent transfer bonuses of its own; see the current LifeMiles transfer bonus analysis.
United MileagePlus, dynamic pricing, but instant confirmation and no phone calls.
Non-Star alternatives worth comparing before you commit:
Virgin Atlantic Flying Club for select partner awards.
Flying Blue for Europe, especially during promo awards.

Who Should Take This Bonus and Who Should Wait
Best for:
Premium Citi cardholders (Strata Elite, Strata Premier, Prestige, AT&T Access More) with a confirmed or near-confirmed Star Alliance partner award.
Travelers booking United domestic economy or long-haul partner business class where Turkish’s partner pricing beats alternatives.
Anyone whose travel is far enough out that receiving the 40% in September is fine.
Not for:
Cardholders limited to the ~0.98 base ratio with no premium card to pool into.
Anyone who needs the full mileage balance available before September 1, 2026.
Speculative transfers with no route in mind, given devaluation risk and the irreversibility of transfers.
Travelers who strongly prefer online self-service booking.
FAQ
Which Citi cards offer the Turkish Airlines transfer bonus?
All ThankYou-earning Citi cards can transfer during the campaign, but the effective value differs. Citi Strata Elite, Strata Premier, Citi Prestige, and AT&T Access More reach 1,400 Turkish miles per 1,000 points. Other ThankYou cards start from a base ratio near 0.98 miles per point.
How do I transfer Citi points to Turkish Airlines?
Log in to your Citi ThankYou account, select Turkish Miles&Smiles as the transfer partner, enter your Miles&Smiles number and matching name, choose an amount in the allowed increments (commonly 1,000-point multiples), and confirm. Transfers cannot be reversed.
When exactly will the 40% bonus miles post?
After the campaign ends on August 31, 2026. The earliest realistic date is September 1, 2026, and Turkish does not publish a guaranteed posting time, so allow days to a few weeks.
Can this bonus be stacked with another Turkish promotion?
No. Treat it as a standalone Turkish campaign that cannot be combined with other Miles&Smiles mileage promotions on the same transfer.
Do the bonus miles count toward Miles&Smiles elite status?
No. Transferred miles and promotional bonus miles are award miles only and do not generate status miles toward Elite or Elite Plus.
How many ThankYou points does it take to max out the bonus?
About 125,000 ThankYou points, which produces the 50,000-mile bonus cap. Transferring beyond that still converts at the base ratio but adds no further bonus.
Is a 40% bonus better than waiting for a bigger future offer?
Turkish bonuses at this level are strong but not unprecedented. If you have a specific award seat, take the current offer. If not, holding your ThankYou points is usually safer than parking a speculative balance in an airline program.
Conclusion and Next Steps
The 40% Citi to Turkish Airlines transfer bonus in August 2026 is a legitimately good ratio for premium Citi cardholders, but the promotion’s design forces a timing decision. Base miles arrive fast; the 40% arrives after the campaign closes. Build your booking plan around that split rather than assuming a single lump-sum deposit.
Do these five things, in order:
Verify the bonus percentage, end date, cutoff time zone, and 50,000-mile cap on Turkish’s official campaign page.
Search Star Alliance saver space for your target route and cabin, and write down the flight numbers.
Price the award in Miles&Smiles, divide by 1.4, and calculate exactly how many ThankYou points you need.
Confirm your Miles&Smiles account name matches your Citi profile, then transfer with at least a day of margin before August 31, 2026.
Save every transfer confirmation, and follow up with Turkish after mid-September if the bonus miles have not posted.
