Summer 2026 is roughly four weeks out, and the inbox question I get most right now is some version of the same trade. Reader has 200,000 Chase Ultimate Rewards points and 150,000 Amex Membership Rewards points sitting in two wallets, a family trip to Europe booked or about to be booked, and a real decision about which currency to spend first. I have run the math on both stacks for years and the answer has shifted in 2026 in ways that matter for this specific window of travel.
The Chase Sapphire Reserve refresh landed earlier this year with Points Boost in full production after its 2025 rollout. Amex has spent the same eighteen months running aggressive transfer bonuses through Membership Rewards while keeping its airline partner roster wider than Chase's. Hyatt continues to deliver redemptions at European city hotels that no other hotel chain in either program comes close to matching. That sets up a cleaner head-to-head than the version of this comparison I would have written a year ago, and the practical answer for summer 2026 turns out to depend on which leg of your trip is the expensive one.
If the most expensive piece of your trip is the flight, the answer is usually Amex. If the most expensive piece is the hotel, the answer is almost always Chase.
How To Score These Programs For Europe Summer
Before I get into partners and portals, I want to put the scoring framework on the table because it explains why this comparison comes out differently than the generic "Chase versus Amex" version that gets recycled on every points blog.
For a European summer trip booked in the next four weeks, your points are doing one of three jobs. They are buying a flight, they are buying a hotel, or they are buying a portal booking when transfer math does not pencil. Each job has a different baseline value, a different timing constraint, and a different sensitivity to transfer bonuses. The right question is not "which program is better." It is "which program is better at the specific job I am asking it to do this summer."
My baseline working numbers right now are Chase Ultimate Rewards at roughly 2.0 cents per point and Amex Membership Rewards at roughly 2.2 cents per point. Those are aggregate averages across thousands of real redemptions and they hide enormous variance. The best Hyatt redemption I will book this summer is around 4 cents per point. The worst portal flight I would book on either program is around 1 cent per point. Averages are a starting point. The actual redemption math is what matters.
Airline Partners
Amex carries a meaningfully wider airline partner roster, and the gap matters more for European travel than for any other region. Amex transfers to 17 airline partners. Chase transfers to 10. Six partners overlap between the two: Air Canada Aeroplan, Air France-KLM Flying Blue, British Airways Avios, JetBlue TrueBlue, Singapore KrisFlyer, and Virgin Atlantic Flying Club. For any of those six, either program gets you to the same award space at the same transfer ratio.
The Amex-only partners that matter for Europe summer are the part of the gap I actually care about. ANA Mileage Club prices Tokyo as the obvious sweet spot, but the program also runs partner awards on Star Alliance carriers transatlantic at well-below-United pricing. Avianca LifeMiles books Star Alliance space at fewer miles than the operating carrier on most European routes and runs frequent transfer bonuses on top. Iberia Plus is the only sensible way to book British Airways flights without getting buried in fuel surcharges. Aer Lingus AerClub gets you from the East Coast to Dublin for fewer miles than any U.S. program will quote. Air France-KLM Flying Blue technically overlaps with Chase, but the monthly Promo Rewards discounts of 25 percent and the frequent transfer bonuses make it an Amex story in practice.
The Chase exclusives are United MileagePlus and Southwest Rapid Rewards. United is the program I would choose last for European travel because it consistently charges more miles than Aeroplan for the same Star Alliance partner space. Southwest does not fly to Europe. Neither exclusive helps for the trip we are actually discussing. The Chase airline partner list is shorter and the missing carriers are the ones doing the most interesting things in Europe right now.
The Transfer Bonus Cadence Gap
This is the Amex advantage that compounds over a year and that most comparison articles underweight. Amex runs transfer promotions to its European airline partners several times a year, and the bonuses are big. In the last twelve months alone, Amex has run 20 to 40 percent bonuses to Flying Blue, British Airways, Iberia, Virgin Atlantic, and Aeroplan. A 30 percent bonus turns a 60,000-point business class award into a 46,000-point business class award. That is not a marginal improvement. That is the difference between burning two welcome bonuses and burning one.
Chase, by comparison, runs airline transfer bonuses rarely. Notable promotions in recent memory have involved Marriott Bonvoy and occasional Hyatt offers, neither of which helps the airline side of a European trip. A reader sitting on Chase points who wants to book a transatlantic business class award is paying full freight at the transfer ratio. A reader sitting on Amex points has a meaningful chance of catching a bonus that prices the same seat for 20 to 40 percent fewer points.
The practical playbook I follow: keep a healthy Amex Membership Rewards balance and watch for bonuses to Flying Blue, Iberia, Virgin Atlantic, and Aeroplan. Time the transfer to the bonus, not the booking. When a 30 percent bonus to Iberia drops, that is the day I move points, even if I have not yet picked the exact flight. Bonuses are time-limited. Award seats are date-limited. Decouple the two and you keep optionality on both sides.
Hotels: Why Hyatt Swings The Whole Category
This is the section that flips the entire comparison the other direction. Chase transfers to World of Hyatt 1:1, and Amex does not. Hyatt is the single most valuable hotel program for points redemptions, and the gap is biggest at European city hotels during summer peak. That alone is enough to make Chase the better currency for any trip where the hotel is the dominant cost.
A few concrete examples from properties I have priced this month for July and August stays. Hyatt Regency Rome Central is a Category 4 hotel at 15,000 points per night. Cash rates for the same nights this summer are $600 and up. That is a redemption value north of 4 cents per point. Hyatt Paris Madeleine is also Category 4 at 15,000 points per night against cash rates of $500 to $700 per night, putting the redemption at 3.3 to 4.7 cents per point. Hyatt Regency London The Churchill is Category 5 at 20,000 points per night against cash rates of $700 to $900, redeeming at 3.5 to 4.5 cents per point.
Now compare what the other Amex hotel partners deliver at the same European city properties for the same summer dates. Marriott Bonvoy redeems at roughly 0.7 cents per point as a baseline, and summer dynamic pricing in European cities bloats the points cost to 80,000 or 100,000 points per night, dropping real-world value to 0.5 to 0.8 cents. Hilton Honors sits at around 0.5 cents per point because cash rates and award rates inflate in sync. IHG One Rewards and Choice Privileges, both available to Amex and Chase respectively, redeem in the 0.5 to 0.6 cents per point band.
The Hyatt redemption is delivering roughly five times the value of the next-best Amex hotel transfer at peak summer European pricing. There is no airline transfer bonus, on any program, that closes that gap. If your summer trip includes four nights in a European city hotel and you are picking between booking it on Chase points through Hyatt or on Amex points through Marriott or Hilton, the math is not close.
The Chase Travel Portal Post-Points-Boost
The 2025 Points Boost rollout reshaped the Chase Travel portal proposition, and the 2026 refresh has now had enough time in market for the numbers to settle. Chase Sapphire Reserve cardholders and Sapphire Reserve for Business cardholders can now book through the portal at up to 2 cents per point on premium airfare and hotels, and up to 1.5 cents per point on standard flights. Chase Sapphire Preferred and Ink Business Preferred cardholders get up to 1.75 cents per point on premium airfare and up to 1.5 cents per point on hotels and select flights.
The Amex Travel portal has not kept pace. The base value sits at around 1 cent per point on airfare and around 0.7 cents per point on hotels. The Business Platinum used to carry a 35 percent Pay With Points rebate on airfare that effectively pushed the portal value up to roughly 1.54 cents per point, but that benefit is now restricted to a single pre-selected airline per cardholder. For most travelers, the Amex Travel portal is a fallback rather than a primary use case.
The practical impact for European summer travel is that Chase points have a competitive floor through the portal in a way that Amex points do not. When transfer math does not work out for a specific flight, or when timing is too tight to wait for an award seat to open, the Chase portal at 1.5 to 2 cents per point is a reasonable backstop. The Amex portal at 1 cent per point usually is not. That changes how you reason about which currency to spend first when a trip mixes award space and revenue space.
Transfer Speed Tactical Edge
Chase transfers to most airline and hotel partners arrive in seconds. Amex transfers can take anywhere from a few hours to 48 hours depending on the partner, and certain partners run longer in busy stretches. For most planned bookings, the speed difference does not matter. For a few specific scenarios, it matters a lot.
If you are watching a single award seat on Flying Blue during the monthly Promo Rewards window and you do not already have miles in your account, the difference between an instant Chase transfer and a multi-hour Amex transfer can decide whether the seat is still there when your points land. The same is true for Aeroplan space on busy transatlantic dates, where two or three other people are watching the same seat. Last-minute positioning, sudden schedule changes, and award space that opens up overnight all favor the program with instant transfers.
This is also why I keep both currencies. Amex gives me the wider partner roster and the transfer bonuses. Chase gives me the instant trigger when an opportunity opens. The combination is meaningfully better than either currency alone for the kind of opportunistic award booking that defines European summer travel right now.
The Combined Stack (What I Actually Do)
For a points player with reasonable spend across both ecosystems, the practical setup is to hold the Sapphire Reserve as the Chase keystone, the Sapphire Preferred or an Ink card for the multipliers, an Amex Platinum or Business Platinum for the Membership Rewards engine, and the Hyatt card for the free night certificate and the elite-night credits. That stack covers the four jobs that actually matter for European summer travel: transferring to Hyatt for hotels, transferring to Amex partners for premium airfare, hitting the Chase portal as a backstop at 1.5 to 2 cents per point, and earning a free night certificate per year at a Category 1 to 4 Hyatt that absorbs an entire night of the trip.
The currency allocation rule I run on every European trip looks like this. Hotel nights at Hyatt come out of Chase. Premium-cabin flights to Europe come out of Amex if a transfer bonus is live or has been live in the last 90 days. If transfer math does not pencil for the flights, the Chase portal at Sapphire Reserve rates is the fallback. Hotel nights outside Hyatt rarely get booked on points at all because the cents-per-point math does not justify it during summer peak. Cash for non-Hyatt hotels, points for everything else.
A Clear Decision Framework
The right choice depends on what your summer trip actually looks like, so here is a framework I would use if I were the reader writing me this question right now.
Pick Amex points first if the trip leans on premium cabin flights, you can wait for or already see a current transfer bonus, you want the widest partner roster for unusual routings, your hotels are flexible or boutique rather than concentrated at Hyatt, and you have time to hunt award space.
Pick Chase points first if hotels are the biggest single line item on the trip, your hotel strategy is Hyatt-heavy and you want 3 to 4 cents per point redemptions, you prefer portal simplicity for the flights, you need instant transfers for time-sensitive bookings, and you are willing to pay slightly more miles for a cleaner booking process.
For a family of four staying four nights in a European city, the Hyatt math alone usually pushes the trip into Chase territory. For a couple booking transatlantic business class with flexible hotel plans, Amex is usually the better starting currency. For a solo traveler going light on hotels and heavy on premium flights, Amex again. For a trip mixing two Hyatt nights with a transatlantic business award, you spend both currencies in different roles and never have to pick one over the other.
Bottom Line
The 2026 head-to-head is closer than it looks on first read because the two programs are now competitive in different lanes. Amex has the wider partner roster, the transfer bonus cadence, and the deeper bench for premium-cabin transatlantic awards. Chase has Hyatt at peak summer European pricing, instant transfers, and a portal floor at Sapphire Reserve rates that no other program currently matches. Neither program is universally better for European summer travel.
The mistake I see most often is treating this as a binary. Most points players doing real European trips should hold both currencies and assign them to specific jobs within a single trip. Spend Chase on Hyatt nights. Spend Amex on premium-cabin flights, especially with a transfer bonus live. Use the Chase portal as a clean fallback when transfer math does not pencil. The combined stack does more than either single currency, and the four weeks between now and summer departure is exactly the right window to set up that allocation before the trip locks in.
