I Didn’t Expect This From Santander Aeromexico Platinum

Follow us on Google

When I first picked up the Santander Aeromexico Platinum credit card, I expected a fairly standard airline co-branded product: some miles, a companion ticket here and there, maybe a bit of lounge access. After putting it side by side with other travel cards and then watching Santander quietly overhaul the entire Aeromexico portfolio in 2026, I realized this card’s story is far more complicated, and in some ways more interesting, than the glossy brochure suggests.

How the Santander Aeromexico Platinum Was Supposed to Work

On paper, the Santander Aeromexico Platinum has long looked like a serious tool for travelers who fly regularly within Mexico and to the United States. It is positioned as a mid to upper tier travel card, with earning rates and benefits tailored to Aeromexico’s loyalty program, now called Aeromexico Rewards. The core promise: put most of your everyday spending on the card and receive outsized value in flights, upgrades and airport comforts, especially if Mexico City is your main hub.

According to Santander’s current product sheet, the card offers a welcome bonus of about 16,000 Aeromexico Rewards points once you reach the equivalent of 500 US dollars in spending during the first three months after activation. It then earns 1.6 points per US dollar on general purchases and 2 points per US dollar on Aeromexico and Aeromexico Rewards spending. That is a relatively rich multiplier by Mexican market standards, especially if you regularly buy tickets directly from the airline or purchase ancillary services like extra baggage or seat selection.

The annual fee, however, is not minor. As of the first half of 2026, Santander lists an annual fee of 4,000 Mexican pesos before tax, with an annual interest rate above 50 percent and a total annual cost (CAT) approaching 80 percent for reference. Those are not charges you can ignore. The implicit message is clear: this card is not for carrying balances or for casual travelers. It is designed for people who will squeeze real travel value from the perks and pay their statement in full.

In practical terms, that value shows up when you redeem for flights and upgrades. A round trip Mexico City to Cancún on an off peak date can often be had for a rough equivalent of 16,000 to 20,000 points, depending on availability and fare class. That means the welcome bonus alone can cover a domestic round trip if you are flexible on dates, and ongoing spending can realistically fund at least one additional domestic ticket a year for a typical middle class household that channels groceries, fuel and utilities through the card.

The Perks You Actually Feel When You Travel

Beyond points, the Aeromexico Platinum’s most tangible benefits start to reveal themselves the moment you step into an airport. Santander highlights complimentary lounge access as a central perk, and this is where many cardholders are pleasantly surprised. The card includes two annual visits to Aeromexico’s Salones Premier within Mexico for the cardholder plus two companions. In practice, that means a family of four can relax in a lounge at Mexico City, Monterrey or Guadalajara before a holiday flight, enjoying snacks, drinks and quieter seating away from crowded departure halls.

On top of that, the card comes with six annual entries to Grand Lounge Elite, Lounge 19 and Terraza Elite in Mexico City’s Terminal 1 and at Felipe Angeles International Airport. These six entries can be used as six solo visits or effectively three visits with one companion. If you fly out of Mexico City in economy on a Friday evening to Tijuana, for example, having a guaranteed seat, Wi-Fi and a light buffet while you wait out delays can feel like a bigger perk than a few percent of cash back.

Another benefit that often surprises new cardholders is the airport transfer service tied to Mexico City’s main airports. Santander advertises three one way rides per year to either the Mexico City International Airport or Felipe Angeles, with up to 300 pesos covered per trip when booked through the dedicated Platinum concierge line. In real life, that might translate into a complimentary app based ride from neighborhoods like Roma Norte or Polanco to the airport, where typical daytime fares often hover in the 250 to 350 peso range depending on traffic.

On the ground, fee free withdrawals at Santander ATMs abroad can matter more than they seem. If you land in Los Angeles or Madrid and need quick cash, using a foreign ATM normally means an immediate surcharge plus currency conversion costs from your home bank. The Aeromexico Platinum waives Santander’s own overseas ATM fee, so while you still face currency spreads, you at least avoid one layer of charges. For frequent cross border travelers who do not want to juggle separate debit accounts, that is a quiet but real advantage.

What Changed in 2026: From Aeromexico Platinum to Unique Rewards Platinum

The twist in this story is that in 2026 Santander began phasing out its Aeromexico branded line in favor of a new family of in house rewards cards. The official announcement states that the Santander Aeromexico Platinum card will be transformed into the Unique Rewards Platinum card, keeping the same card number, credit limit and payment dates, but changing the name and benefits. The general migration date is framed around June 30 and July 1, 2026, after which new spending earns Santander’s own Unique Points rather than Aeromexico Rewards.

For current cardholders, this means that all Aeromexico Rewards points accumulated up to June 30 remain safely in their airline loyalty account. They are not lost or converted, and they continue to follow Aeromexico’s usual expiration and redemption rules. What does change is the way new spending is rewarded. Under the Unique Rewards Platinum branding, Santander now advertises earnings of 2 Unique Points per US dollar on general purchases and 3 Unique Points per US dollar on airline spending, plus a different set of redemption options that include flights on multiple carriers, hotels, gift certificates and experiences.

The new card also comes with a different profile of travel benefits. Santander promotes ten annual entries to more than 1,800 airport lounges worldwide via LoungeKey for Unique Rewards Platinum, a noticeable shift away from the Mexico focused mix of Salones Premier and Grand Lounge access tied specifically to Aeromexico. For someone who spends as much time connecting in Bogotá or Madrid as in Mexico City, global LoungeKey coverage could easily be more useful than a handful of entries to a single airline’s lounges.

This transformation caught many Aeromexico focused travelers off guard because, until recently, the Santander Aeromexico Platinum was one of the most straightforward ways to deepen your relationship with Aeromexico through a bank product. If you built your strategy around that partnership, you now have to rethink how you earn airline miles on everyday spending, particularly after mid 2026 when new purchases stop generating Aeromexico Rewards and start accumulating Unique Points instead.

Comparing Santander Aeromexico Platinum With Airline and Bank Rivals

Putting the Aeromexico Platinum next to its competitors helps explain why the card once made sense for certain profiles and why the 2026 change is so significant. On the airline side, Aeromexico also partners with American Express in Mexico. The Platinum Card American Express Aeromexico, which is a different product from the global Platinum Card, combines Aeromexico Rewards earning with premium lounge access at Centurion Lounges in Mexico City and other airports, along with higher annual fees and a more luxury focused proposition.

If you fly Aeromexico once a month in business class, sail through Mexico City in the early morning rush and value high quality food and showers during layovers, that American Express product can easily justify its price. However, for a traveler who mostly flies economy between Mexican cities three to four times a year and occasionally to Texas or California, the Santander Aeromexico Platinum offered a more balanced package: lower fees, targeted lounge access and tangible perks like the 2x1 anniversary certificate for a domestic flight with a companion.

On the bank side, Santander’s own LikeU and Unique Rewards cards, plus competitors from institutions such as BBVA and Citibanamex, mostly focus on cash back or flexible points. A general cash back card that returns 2 percent on everyday spending might net you the equivalent of 4,000 pesos a year if you spend around 200,000 pesos, which is roughly comparable in value to a couple of domestic flights booked with well used Aeromexico Rewards points. The trade off is psychological as much as financial: some travelers prefer watching mile balances grow toward an aspirational redemption, while others prefer the simplicity of a statement credit or supermarket discount.

What made the Aeromexico Platinum distinctive before its transformation were the layered airline specific perks: bonus points on Aeromexico spending, priority check in and boarding on eligible flights and that domestic 2x1 certificate each anniversary. Even if you rarely used the lounges, the certificate alone could offset a significant part of the annual fee if you redeemed it for a popular route such as Mexico City to Tijuana during school holidays, when cash fares can climb well above 3,000 pesos return per person.

The Hidden Costs and Limitations Travelers Discover Late

Set against all those headline perks are the card’s limitations, which many travelers only appreciate after a year or two. First, the annual fee is charged regardless of how often you fly. A family that takes a single round trip vacation flight each year may find that the 4,000 peso fee, plus tax, outweighs the value of lounge visits and a companion certificate, especially if they could have found similar fares in Aeromexico’s own promotions without loyalty benefits.

The second hidden cost is the card’s high ongoing interest rate. With a reference annual rate above 50 percent and a very high total annual cost, using the Aeromexico Platinum as a long term borrowing tool is painful. A traveler who charges a 10,000 peso holiday package to the card and then pays only the minimum each month can watch interest quickly erode any value generated by bonus points or airline perks. This is not unique to Santander, but it is especially critical with a rewards card carrying a premium fee.

There are also geographic constraints. The bulk of the value sits within Mexico, especially in Mexico City. The included lounge entries are concentrated in Mexican airports, and the airport transfer credits apply only to local airports. If you move abroad or shift your travel patterns toward Europe or Asia, much of what made the Aeromexico Platinum attractive begins to look less compelling compared with a global travel card that includes Priority Pass or worldwide insurance coverage.

Finally, the 2026 switch to Unique Rewards means that anyone applying today or holding the card through mid 2026 needs to pay attention to transition dates. A traveler who signed up in early 2026 expecting to build a large Aeromexico Rewards balance entirely through card spending may feel blindsided when new purchases start generating bank points instead of airline miles. The key is to factor that shorter runway into your decision and to consider whether you should accelerate certain purchases before the changeover or, alternatively, pivot to a different card that remains tightly integrated with Aeromexico’s loyalty scheme.

Real World Use Cases: Who Still Gets Value From It?

Despite all these caveats and the ongoing migration to Unique Rewards Platinum, there are still concrete traveler profiles that can extract good value from the Santander Aeromexico Platinum today. Consider a consultant based in Guadalajara who travels to Mexico City twice a month on Aeromexico for client meetings and occasionally to Monterrey. Over a year, that pattern can easily add up to 20 to 25 round trips. If she pays for most of those flights out of pocket and charges hotel stays and meals to the card, she can accumulate enough points for several domestic reward tickets or upgrades, while also using the lounges to work productively during layovers.

Another scenario is a family in Mexico City that visits relatives in Mérida every Christmas and makes one additional beach trip to Puerto Vallarta in the summer. If they plan carefully, the welcome bonus plus annual spending could cover one family member’s ticket at Christmas via points, while the 2x1 anniversary certificate reduces the cost of the summer trip. Using the included airport transfers on their three busiest departure days of the year saves taxi money and avoids the stress of hunting for rides in holiday traffic.

However, if you are a digital nomad based in Lisbon or Bogotá who only passes through Mexico intermittently, the card’s value proposition deteriorates quickly. You might appreciate a couple of lounge visits in Mexico City, but a global product such as a premium Visa or Mastercard with LoungeKey access in multiple regions and a flexible points currency will likely suit your lifestyle better. That is precisely the positioning Santander is moving toward with the Unique Rewards Platinum, which is why some travelers may welcome the 2026 change rather than mourn the end of the Aeromexico co brand.

For US based travelers, the calculus is even more nuanced. If you live in Texas or California and fly Aeromexico to Mexico City a few times a year, you might be better off with a US issued travel card that earns transferable points to airline partners and includes priority boarding or free checked bags on a domestic carrier. Cross border card use can still be interesting due to occasional promotions and foreign exchange dynamics, but the fees and complexity often outweigh the benefits unless you have strong financial ties to Mexico.

The Takeaway

Looking back, what I did not expect from the Santander Aeromexico Platinum was how tightly its value is woven into both a specific airline and a specific moment in the Mexican card market. For several years, it was an unusually coherent proposition for travelers who lived near Aeromexico hubs, flew the airline frequently and wanted to layer lounge access, airport transfers and priority services on top of miles earning, all through a single product.

The 2026 transformation into Unique Rewards Platinum changes that equation. The card is gradually shifting from a deeply Aeromexico centric tool to a more flexible bank rewards platform with broader lounge access and a more generalist earning structure. Some travelers will lose the direct psychological connection between card spending and Aeromexico miles, while others will gain redemption flexibility and a more international profile of travel perks.

If you are evaluating this card now, the most important step is to map the benefits to your actual travel patterns over the next two or three years. Ask yourself how often you really fly Aeromexico, how much time you spend in Mexican airports and how disciplined you are about paying your balance in full. The Santander Aeromexico Platinum, in its classic form, still offers meaningful value to the right traveler, but only if you approach it with clear eyes about fees, timelines and the coming shift in how your spending is rewarded.

Ultimately, credit cards are tools, not trophies. The surprise is not that benefits change, but that a mid tier airline card like this one could, for a time, stitch together enough well chosen perks to genuinely improve the travel experience of a very specific kind of flyer. As Santander and Aeromexico go their separate ways in the card space, the lesson for travelers is simple: always read the fine print, and always compare the card you hold not only with competitors, but with what that same card will look like one or two years from now.

FAQ

Q1. Is the Santander Aeromexico Platinum card still available in 2026?
As of mid 2026, Santander is in the process of transforming existing Santander Aeromexico Platinum cards into Unique Rewards Platinum cards, so new applicants are typically directed to the new product rather than the legacy Aeromexico version.

Q2. Will I lose my Aeromexico Rewards points when my card changes to Unique Rewards Platinum?
No. Points earned up to the cutoff date remain in your Aeromexico Rewards account and continue under the airline’s rules. What changes is that future spending starts earning Santander’s Unique Points instead of Aeromexico Rewards miles.

Q3. How many lounge visits did the Santander Aeromexico Platinum card include?
The legacy card included two annual accesses to Aeromexico’s Salones Premier for the cardholder plus two companions, plus six annual entries to Grand Lounge Elite, Lounge 19 and Terraza Elite in Mexico City and Felipe Angeles airports.

Q4. What is the current annual fee for the Santander Aeromexico Platinum card?
Santander lists an annual fee of approximately 4,000 Mexican pesos before tax for the Aeromexico Platinum, although exact amounts can change over time and may be updated as the card transitions to Unique Rewards Platinum.

Q5. Does the Santander Aeromexico Platinum card waive foreign ATM fees?
The card waives Santander’s own fee for using its ATMs abroad, which can reduce costs when withdrawing cash overseas. You may still face currency conversion spreads or local operator surcharges.

Q6. What happens to my airport transfer benefit after the card transforms?
Under the Aeromexico Platinum benefits, cardholders receive three one way transfers per year to Mexico City area airports with a capped amount covered per ride. How this benefit is handled after full migration to Unique Rewards Platinum depends on Santander’s updated benefit package, so you should check the latest terms before relying on it.

Q7. Is the Santander Aeromexico Platinum card worth it for travelers who only fly once a year?
For occasional travelers who take a single round trip flight per year, the annual fee and high interest costs often outweigh the value of lounge access and companion certificates. A lower fee cash back card or a flexible points product may be more suitable.

Q8. How did the earning rate on the Santander Aeromexico Platinum compare with other Mexican cards?
The card’s 1.6 points per US dollar on general spending and 2 points per US dollar on Aeromexico purchases was relatively strong for a co branded airline card in Mexico, especially for travelers who consistently booked directly with Aeromexico.

Q9. If I want to keep earning Aeromexico Rewards with a card, what are my options now?
Travelers can look at Aeromexico’s co branded cards with American Express in Mexico or other financial partners that still issue Aeromexico linked products. It is important to review current terms, fees and earning rates, as these can differ significantly from the former Santander Aeromexico line.

Q10. Does it make sense to keep the Santander card after it becomes Unique Rewards Platinum?
It can, depending on your pattern of spending and travel. If you value global LoungeKey access and flexible bank points that can be used for flights, hotels and experiences beyond Aeromexico, the Unique Rewards Platinum may be a strong fit. If your priority is maximizing Aeromexico Rewards miles specifically, you may want to pair or replace it with a card that still earns directly in that program.
