How to Transfer Citi ThankYou Points to Singapore KrisFlyer (2026)

Quick answer

Citi ThankYou points transfer to Singapore Airlines KrisFlyer at 1:1, unlocking access to one of the world's most coveted premium cabin products. Singapore Suites — their double-bed first class suite — consistently ranks as the world's best first class. Business Class (SilverKris) is among the top 3 globally. At 95,000–115,000 miles for Suites and 78,000 for Business Class to Singapore from the US, TY transfers to KrisFlyer can deliver some of the highest cents-per-mile values possible.

TL;DR: Citi ThankYou points transfer to Singapore Airlines KrisFlyer at 1:1. Transfer takes 1–3 business days. Best redemptions: Singapore Suites from US to Singapore (95,000–115,000 miles one-way), Singapore Business Class (78,000 miles round trip from US East Coast). KrisFlyer uses Saver and Advantage pricing. Saver space must be confirmed before transfer. Advantage pricing is more expensive but easier to find.

Why Singapore KrisFlyer

Singapore Airlines is regularly voted the world's best airline. Their premium products are particularly compelling when you understand how the Citi ThankYou program works and its full roster of transfer partners:

Singapore Suites (First Class)

Available on A380 flights to select destinations. Features private suites with closing doors, double beds when flying with a partner, personal butler service, and Restaurant à la Carte dining. Cash price: $15,000–$25,000+ one-way to Singapore. Nearly impossible to book with cash during busy periods.

Singapore Business Class (SilverKris)

Available on A380 and A350 flights. Direct aisle access from every seat, fully flat beds, and Singapore's legendary service. Cash price: $4,000–$8,000 one-way to Asia.

Transfer mechanics

• Transfer ratio: 1 ThankYou point = 1 KrisFlyer mile (1:1)
• Transfer time: 1–3 business days (not instant)
• Minimum transfer: 1,000 points
• KrisFlyer miles expiration: Miles expire 3 years from date of earning, or 12 months from last activity — check your KrisFlyer account

Critical: KrisFlyer uses two award types:

• Saver awards: Fixed mileage (the values in this guide). Limited availability, must be confirmed before transferring. See the Citi ThankYou sweet spots guide for other high-value redemptions in the program.
• Advantage awards: ~30% more miles. Available on any regular fare, but more expensive. Easier to find for last-minute travel.

Award pricing for US travelers

US East Coast → Singapore (one-way, Saver)

US West Coast → Singapore (one-way, Saver)

Singapore → Europe (one-way, Saver)

Value calculation

Singapore Suites (US East Coast → SIN): 114,500 miles, cash cost ~$20,000. Value: 17–18 cents per mile — among the highest achievable with any currency.

Singapore Business (US → SIN, round trip): 155,000 miles (2 × 77,500), cash cost ~$10,000–$15,000. Value: 6–10 cents per mile.

How many TY points do you need

For a round-trip Singapore Business from the US West Coast (roundabout):

• 2 × 74,500 = 149,000 KrisFlyer miles
• Citi Strata Premier welcome bonus, if Citi is running one when you apply, plus ongoing 3x category spend
• At 3x dining on Strata Premier: $25,000 in dining spend

For Singapore Suites one-way from US East Coast:

• 114,500 miles needed
• Whatever welcome bonus Citi is running, plus the balance from ongoing 3x spend
• At 3x dining + 3x hotel spend combined: 6–8 months of heavy Citi TY earning

Step-by-step transfer guide

1. Search Saver award availability first at singaporeair.com → Book → Book with KrisFlyer miles. Confirm your exact flights and dates BEFORE transferring.
2. Create a KrisFlyer account if you don't have one (free, takes 5 minutes).
3. Log in to thankyou.com and navigate to Transfer Points.
4. Select Singapore Airlines KrisFlyer from the partner list.
5. Enter your KrisFlyer membership number (9-digit number from your account).
6. Transfer the required number of points — verify you're transferring enough for your specific award.
7. Wait 1–3 business days for miles to post.
8. Book the award immediately after miles appear. Hold inventory for 24–48 hours in some cases.

Singapore Airlines partner routes via KrisFlyer

You can also book Star Alliance partner airlines using KrisFlyer miles — though this has become more expensive in recent years. For a full breakdown of which programs offer the best Star Alliance rates, see the complete list of Citi ThankYou transfer partners:

• Lufthansa (but fuel surcharges apply — use Turkish instead)
• ANA All Nippon Airways (alternative to AAdvantage)
• United Airlines (possible but usually more expensive than LifeMiles)

For most Star Alliance partners, Avianca LifeMiles or Turkish Miles & Smiles are better options. KrisFlyer shines specifically for Singapore Airlines own metal.

KrisFlyer miles expiration policy

• Miles earned from credit card transfers: expire 3 years from date earned
• Miles earned from flights: expire 12 months from last earning activity
• Extend expiration: book an award, earn miles by flying, or transfer more points

Don't transfer miles to KrisFlyer speculatively — only do so when you have confirmed award availability to book. If you're building a multi-card earning strategy, the Citi trifecta setup can significantly accelerate how quickly you accumulate points for a redemption like this.

Comparing Citi TY Singapore KrisFlyer vs other paths

Citi TY and Amex Membership Rewards are the two primary US credit card currencies with direct KrisFlyer transfer access.

Bottom line

Singapore Airlines KrisFlyer is one of the best-value transfers in the Citi ThankYou program — and one of the top picks when you look at how to maximize Citi ThankYou points. If you're targeting Singapore Suites or Business Class, your Strata Premier ThankYou points are one of the best earning vehicles available in the US market. Always confirm Saver availability before transferring — KrisFlyer miles take 1–3 days to post, and award space on Singapore's premium cabins is genuinely limited.
