Transfer Partner Overlap: Which Points Currency Offers the Most Unique Access?
An analysis of how much the transfer partner networks of Chase Ultimate Rewards, American Express Membership Rewards, Citi ThankYou, and Capital One Miles overlap — and which partners are exclusive to a single program.
Key Takeaways
- World of Hyatt is accessible only through Chase among the four major transferable programs — Amex, Citi, and Capital One do not transfer to Hyatt
- Delta SkyMiles is accessible only through American Express among the four programs — Chase, Citi, and Capital One do not transfer to Delta directly
- British Airways Avios appears in all four networks (Chase, Amex, Citi via Citi Strata, Capital One), making it one of the least differentiating partners
- Singapore KrisFlyer appears in Chase, Amex, and Citi but not Capital One, giving the first three programs an edge for Singapore Airlines redemptions
- Air France-KLM Flying Blue is the most widely available airline partner, accessible through all four programs at 1:1 ratios
- Capital One's 23-partner network includes EVA Air, Japan Airlines, and I Prefer Hotel Rewards that appear in none of the other three programs
Methodology
Data Source
Publicly available transfer partner lists for Chase Ultimate Rewards, American Express Membership Rewards, Citi ThankYou Rewards, and Capital One Miles as of early 2026
Approach
Transfer partner lists were compiled from each program's official transfer partner page. Partners were cross-referenced across all four programs to identify exclusive partners (appearing in exactly one program), broadly available partners (appearing in three or four programs), and mid-overlap partners (two programs). Transfer ratios were noted where non-standard.
Limitations
- • Transfer partner networks change; exclusivity findings reflect early 2026 and may have shifted
- • Some transfers operate at non-1:1 ratios (e.g., Amex to Emirates at 5:4, Amex to JetBlue at 250:200) — these partners are included but the ratio differential affects practical value
- • Analysis covers major U.S. transferable programs only — Bilt Rewards and bank-specific programs like Wells Fargo are not included
- • Partner network size (14 vs 20 vs 23) is not directly comparable to value — a smaller network with better partners may outperform a larger one
Background
The four major U.S. transferable points programs — Chase Ultimate Rewards (14 partners), American Express Membership Rewards (20 partners), Citi ThankYou Rewards (~12 airline and hotel partners on premium cards), and Capital One Miles (23 partners) — are often compared by total partner count. That framing misses the more practically useful question: if you already hold one program, which partners are you not accessing?
Overlap analysis reveals which partners are genuinely differentiating and which appear across so many programs that they provide no competitive reason to choose one currency over another.
Key Findings
Chase: The Hyatt Moat
World of Hyatt is the most consequential exclusive in the competitive set. Among the four programs analyzed, only Chase Ultimate Rewards transfers to Hyatt. American Express, Citi, and Capital One have no direct Hyatt transfer path. For cardholders who value Hyatt's Globalist benefits — breakfast, suite upgrades, and late checkout — or who want to redeem for high-value Category 1–7 properties, Chase is structurally irreplaceable.
Chase's airline-side exclusives are more modest. Southwest Rapid Rewards transfers only through Chase among the four programs, which matters to domestic US travelers but carries less weight internationally.
American Express: The Delta Lock-In
Delta SkyMiles is accessible only through American Express Membership Rewards among the four programs. Given Delta's hub dominance in Atlanta, Boston, Los Angeles, Minneapolis, and New York (JFK), this exclusivity has real operational value. For travelers who fly Delta regularly and want to top off SkyMiles balances with transferable points, Amex is the only path.
American Express is also one of only two programs (alongside Chase) to offer United MileagePlus transfers, though Chase's United partnership is the more widely documented of the two.
Broadly Available Partners: Less Differentiating
British Airways Avios is available through all four programs, making it one of the weakest arguments for any single currency. Air France-KLM Flying Blue is similarly available across Chase, Amex, Citi, and Capital One at 1:1 ratios. Avianca LifeMiles appears in Amex, Citi, and Capital One. Singapore KrisFlyer appears in Chase, Amex, and Citi. These broadly available partners should not drive program selection — they are accessible from multiple positions.
Capital One: Unique Airlines, No Major Hotel
Capital One's 23-partner network includes EVA Air Infinity MileageLands, Japan Airlines Mileage Bank, and I Prefer Hotel Rewards — none of which appear in the other three programs. However, Capital One lacks access to the three most-discussed hotel programs: Hyatt (Chase only), Marriott (Chase and Amex), and Hilton (Amex only). Travelers focused on hotel redemptions are poorly served by Capital One alone.
Practical Implication: One Card Is Not Enough
No single program covers all high-value partners. A cardholder holding only Chase cannot reach Delta or Hilton. A cardholder holding only Amex cannot reach Hyatt. A two-card combination of Chase (for Hyatt, Southwest) and Amex (for Delta, Hilton) covers the most consequential gaps at the cost of managing two ecosystems.
Implications for Users
- If you prioritize hotel redemptions: Chase is required for Hyatt access; Amex provides Hilton and Marriott
- If you fly Delta regularly: Amex Membership Rewards is the only transferable currency that reaches SkyMiles
- If you target British Airways Avios or Air France Flying Blue: program choice is not a differentiator — all four programs transfer to these
- If you want the broadest airline coverage: Capital One's 23 partners include several that other programs lack, at the cost of weaker hotel access
Methodology
Transfer partner lists were extracted from each program's official partner page in early 2026. Partners were mapped into a cross-reference table and categorized by exclusivity level. Non-standard transfer ratios (Amex to Emirates at 5:4, Amex to JetBlue at 250:200, Capital One to Emirates at 4:3) were noted but partners were counted as present in that program regardless of ratio.
Limitations
Transfer partner networks change without notice. The Citi ThankYou network in particular has expanded rapidly, and the findings above may be outdated within months. Additionally, this analysis counts access, not value — a partner being available does not mean redemptions through that partner are competitive. Users should verify current partner lists and transfer ratios before making card decisions based on partner access.
