For frequent flyers in North America, airline co-branded credit cards can feel almost essential. But when you are choosing between the Santander Aeromexico Platinum, aimed squarely at Mexico-based Aeromexico loyalists, and the premium Air Canada Aeroplan Reserve card, the better choice is not always obvious. Each card is built for a different type of traveler, with distinct strengths in route networks, lounge access and everyday usability. Understanding those nuances is key before you commit to either annual fee.

Card Profiles at a Glance

The Santander Aeromexico Platinum is a Mexican peso credit card issued by Santander Mexico in partnership with Aeromexico. It is designed primarily for residents of Mexico who fly Aeromexico often, whether that is commuting between Mexico City and Monterrey or flying long haul from Guadalajara to Madrid via Aeromexico’s Europe network. The card earns Aeromexico’s Puntos Premier on daily spending and layers in travel benefits such as companion tickets, access to some Aeromexico lounges and travel insurance.

The Air Canada Aeroplan Reserve, issued by American Express in Canada, is a top-tier Aeroplan product targeted at travelers who regularly fly Air Canada and Star Alliance partners. It comes with a high annual fee in Canadian dollars but compensates with strong earning rates on Air Canada purchases, unlimited Maple Leaf Lounge access in North America when flying eligible airlines, Priority Pass membership for access to third-party lounges, and an annual worldwide companion pass after significant spend.

Although both are airline co-branded, they operate in different markets and currencies, with reward programs tied to different alliances. Aeromexico is part of SkyTeam, while Air Canada anchors Star Alliance. That single difference alone can tip the scales depending on whether your typical trips are to SkyTeam hubs like Paris and Amsterdam or to Star Alliance strongholds like Frankfurt and Tokyo.

From a practical standpoint, it is rare for the same traveler to be equally embedded in both ecosystems. A Mexico City entrepreneur flying Aeromexico monthly to New York may maximize value from Santander Aeromexico Platinum, while a Toronto-based consultant commuting to San Francisco and London will usually do better with Aeroplan Reserve. Still, many travelers based in the United States or frequent cross-border flyers could realistically choose either, so a clear side‑by‑side comparison matters.

Annual Fees, Currency and Cost of Ownership

One of the first differences you will notice is how each card handles annual cost. The Santander Aeromexico Platinum typically charges an annual fee in the range of 3,000 to 3,500 Mexican pesos, with some issuers advertising a first year with no annual fee as a promotional hook. That means a new cardholder in Mexico City might pay no fee in year one, then around 3,200 pesos from year two onward, which is roughly equivalent to a mid-tier North American travel card.

The Air Canada Aeroplan Reserve card, on the other hand, sits firmly in premium territory. Its annual fee is usually in the mid-600 Canadian dollar range, comparable to other high-end Canadian travel cards. For a Montreal-based traveler, that is a significant outlay every year. However, for someone who checks bags frequently, visits lounges often and values priority airport services, the monetary value of those perks can quickly add up to more than the fee, especially if you routinely pay out of pocket for airport food or checked luggage.

Currency choice also impacts how you experience the card. Santander Aeromexico Platinum operates in pesos, which makes it far more natural for everyday spending in Mexico: groceries at a Chedraui supermarket, rides with Uber charged in MXN, or restaurant bills in Mexico City’s Roma neighborhood. You avoid foreign transaction surcharges on local purchases, and your statement balances match your income currency. By contrast, Aeroplan Reserve statements arrive in Canadian dollars. That is ideal if you earn in CAD and spend much of your time in Canada, but less convenient for someone whose primary base is in Mexico or the United States.

Cost of ownership in real life can be illustrated with an example. A business traveler in Guadalajara who flies Aeromexico economy to Los Angeles four times a year, checks a bag on each trip, and uses a lounge two or three times per year might find that the Santander card’s included benefits offset its peso fee relatively easily. Meanwhile, a Vancouver-based consultant flying Air Canada six to eight times per year, usually in economy with a checked bag and frequent lounge visits, often recoups the Aeroplan Reserve annual fee through free bags, Maple Leaf Lounge access and the value of the annual companion ticket, especially on long-haul routes to Europe or Asia.

Points Earning and Redeeming: Puntos Premier vs Aeroplan

When you spend on the Santander Aeromexico Platinum, you earn Aeromexico Puntos Premier. While exact earn rates can vary by promotion, the general structure gives you a baseline number of points per unit of spend, with bonuses for purchases in travel categories or made directly with Aeromexico. For example, booking a Mexico City to Madrid round trip on Aeromexico and paying with the Santander Aeromexico Platinum can generate an attractive stack of Puntos Premier: you earn miles from the ticket itself, then additional points from the credit card transaction.

Those Puntos Premier can be used for Aeromexico award tickets and upgrades, as well as for flights on SkyTeam partners such as Delta, Air France and KLM. In practice, that means a traveler could redeem points for a Delta flight from Mexico City to Atlanta or an Air France flight from Mexico City to Paris. However, availability and pricing can be variable, and many cardholders in Mexico report that the best value is often found on Aeromexico-operated routes where promotional award levels appear regularly.

The Aeroplan Reserve card feeds directly into Air Canada’s Aeroplan program, which has become one of the more flexible airline loyalty schemes in North America. Cardholders typically earn three Aeroplan points per dollar on Air Canada and Air Canada Vacations purchases, a robust rate for big-ticket items like long‑haul tickets or vacation packages. Everyday categories such as dining or groceries in Canada often earn at a boosted rate compared with uncategorized spend, though the exact multipliers depend on the latest card configuration.

Aeroplan points can be redeemed on Air Canada and across Star Alliance partners, including United, Lufthansa, Swiss, ANA and many more. In real life, that means a Winnipeg-based traveler could book a single Aeroplan award that connects on United from a U.S. gateway to an interior American city, or a Calgary flyer could piece together a complex route to Southeast Asia via Tokyo using ANA and Air Canada metal on a single award. Aeroplan also permits stopovers on one-way awards for an extra points surcharge, which can create high-value itineraries such as Vancouver to Zurich with a multi-day stop in Lisbon on a Star Alliance partner.

For most travelers who value flexibility and access to a deep partner network, Aeroplan points are more versatile than Puntos Premier. They provide more routes, more partners and generally more ways to avoid high surcharges by carefully choosing partner airlines. That does not mean Puntos Premier are weak; they can still deliver solid value on Aeromexico routes, especially within the Americas and to select European destinations. But in a direct comparison, the scope and global utility of Aeroplan tilts the scale toward the Air Canada card for international award hunters.

Lounge Access and Airport Comfort

Lounge access is one of the most tangible perks for frequent flyers, since it directly improves the airport experience. The Santander Aeromexico Platinum card typically includes access to Aeromexico’s Salones Premier lounges in select airports when you are flying on qualifying Aeromexico tickets. For instance, a cardholder departing from Mexico City International Airport on an Aeromexico flight to Tijuana may be able to access the Salon Premier to enjoy snacks, beverages and quieter seating before boarding. Some versions of the card or associated packages can also include limited Priority Pass or similar lounge program visits, though these are usually capped and may involve additional fees after a small number of visits.

The Aeroplan Reserve card is more generous for travelers who frequent Canadian and U.S. gateways served by Air Canada. It provides unlimited access to Air Canada Maple Leaf Lounges and Air Canada Cafes in Canada and the United States for the primary cardholder, and often for eligible supplementary cardholders, when flying on same-day itineraries operated or marketed by Air Canada or Star Alliance partners. In practice, that means a Toronto-based traveler flying economy from Toronto Pearson to New York LaGuardia on Air Canada can wait in the Maple Leaf Lounge with complimentary food and drinks, fast Wi‑Fi and comfortable workspaces.

Beyond Maple Leaf Lounges, Aeroplan Reserve cardholders receive a Priority Pass membership. While the complimentary visits can be limited depending on card version, this still opens doors to hundreds of third-party lounges worldwide. An example would be using a Priority Pass lounge at London Heathrow while connecting onward to an Air Canada flight back to Montreal, or accessing a contract lounge in Lima between two Star Alliance segments.

For someone whose travel is mainly within Mexico and on Aeromexico, the Santander Aeromexico Platinum’s lounge access can be sufficient and convenient. But for a traveler who often passes through Toronto, Montreal, Vancouver or other Air Canada hubs, the Aeroplan Reserve’s Maple Leaf Lounge access is a major upgrade in comfort. Combined with Priority Pass, it covers more airports and more situations, particularly on long-haul international routes and multi-leg itineraries through global hubs.

Flight Perks: Checked Bags, Priority Services and Companions

Both cards come with flight perks, but the details and real-world impact differ significantly. The Santander Aeromexico Platinum typically offers up to two companion tickets per year, allowing you to bring a travel partner on select Aeromexico flights at a reduced fare or with special conditions. Used cleverly, this can offset the annual fee several times over, for example by booking a Mexico City to New York round trip during a busy holiday period and only paying full fare for one ticket while securing a discounted companion seat.

The card also often includes priority check-in and priority boarding on Aeromexico flights. That can be especially valuable on crowded domestic routes like Mexico City to Cancun or Tijuana, where general boarding queues are long and overhead bin space fills quickly. Being able to check in at a dedicated counter and board early improves the travel day even if you are flying in economy.

The Aeroplan Reserve card’s benefits focus more on baggage and priority services for the cardholder and travel companions. A standard perk is a free first checked bag on Air Canada flights for the primary cardholder and usually up to eight companions on the same reservation. In a real-world example, a family of four flying from Calgary to Honolulu on Air Canada in economy could save hundreds of dollars in baggage fees on a single trip simply by having one Aeroplan Reserve card linked to the booking.

In addition to baggage, Aeroplan Reserve offers priority check-in, priority boarding and often priority baggage handling, which means your bag appears earlier on the carousel at the destination. For frequent flyers who value time, this can be a major quality-of-life improvement. The card also provides an Annual Worldwide Companion Pass when you meet a predefined yearly spend threshold. Used on an international route like Toronto to London in economy or premium economy, the companion pass can yield substantial savings, especially during peak travel seasons such as late June and December.

In short, Santander Aeromexico Platinum leans heavily into companion ticket value and basic priority services within the Aeromexico ecosystem, while Aeroplan Reserve concentrates on making Air Canada trips smoother through free checked bags, priority treatment and a flexible annual companion ticket that works on many global routes.

Insurance, Protections and Everyday Usability

Travel and purchase protections are a crucial but often underappreciated part of premium credit cards. The Santander Aeromexico Platinum card generally includes international emergency medical coverage on trips when the airfare is paid with the card, along with travel accident insurance, trip delay or cancellation coverage and baggage delay protection, though exact amounts and conditions vary. For a Monterrey-based traveler headed to Chicago for a week, this can mean peace of mind that a medical emergency abroad will not result in catastrophic out-of-pocket costs, at least up to the policy limit.

The card also typically offers purchase protections such as extended warranty on eligible items and protection against theft or damage shortly after purchase. Buying a new laptop in Mexico City with the Santander card, for example, could extend the manufacturer warranty by an extra year and provide coverage if the laptop is stolen within a specified period.

The Aeroplan Reserve card typically provides a more extensive protective net. Its travel insurance suite often includes strong out-of-country emergency medical coverage for eligible travelers, trip interruption and cancellation protection, lost or delayed baggage insurance, and flight delay coverage that can reimburse meals and hotels when a connection is missed for covered reasons. A Toronto-based traveler connecting through Vancouver on the way to Tokyo, for instance, may be covered for a hotel stay and meals if a weather delay forces an overnight stop and they booked the ticket with the Aeroplan Reserve.

On the everyday side, Aeroplan Reserve doubles as a premium Canadian payment tool for groceries, dining and gas, often with elevated earn rates in those categories. For a resident of Ottawa using the card for daily expenses, the combination of strong category earning, Aeroplan redemption flexibility and robust travel insurance creates a compelling one-card solution. By contrast, Santander Aeromexico Platinum is most powerful when used by someone whose core life and spending are in Mexico and who prioritizes Aeromexico flights. It works less well as an all-rounder outside Mexico because of the currency, reward structure and narrower airline network.

Which Card Is Better for Different Types of Travelers?

For Mexico-based Aeromexico loyalists, the Santander Aeromexico Platinum is often the better fit. If you live in cities like Mexico City, Monterrey or Guadalajara, fly Aeromexico multiple times a year to domestic and U.S. destinations, and appreciate benefits like companion tickets, priority boarding and access to Salones Premier, this card aligns naturally with your patterns. For example, an executive in Mexico City who flies Aeromexico economy to Miami six times per year, usually checks at least one bag and often travels with the same companion, can extract outsized value from the companion certificates and priority services compared with the annual peso fee.

If, on the other hand, you are Canada-based or frequently flying from Canadian hubs on Air Canada and Star Alliance, the Aeroplan Reserve generally wins. A Toronto or Vancouver resident flying regularly to New York, London, Frankfurt or Tokyo on Air Canada will benefit from free checked bags on virtually every trip, unlimited Maple Leaf Lounge access in North America and a robust Aeroplan earning structure that speeds up premium cabin redemptions. The annual worldwide companion pass can be used for high-value itineraries, such as a summer trip from Montreal to Paris in premium economy with a spouse or partner, slashing the cost of the second ticket.

For U.S.-based travelers who split their time between Mexico and Canada, the choice is more nuanced. Someone living in Los Angeles who spends several months each year in Mexico and frequently flies Aeromexico could justify Santander Aeromexico Platinum, especially if they also maintain a separate U.S. dollar travel card. Meanwhile, a New York-based consultant working often in Toronto and Montreal might instead anchor their strategy around Aeroplan Reserve, using it not only for flights but also for every grocery and dining purchase in Canada, then pairing it with a U.S.-issued card for domestic American spend.

Ultimately, the better card comes down to where you live, which airline you actually fly most often and which network you value. If you want to maximize SkyTeam travel centered on Mexico, Santander Aeromexico Platinum stands out. If your world is built around Air Canada, Star Alliance and Canadian airports, Aeroplan Reserve is usually the stronger and more globally flexible tool.

The Takeaway

Choosing between the Santander Aeromexico Platinum and the Air Canada Aeroplan Reserve is less about which card is absolutely better and more about which one is better for your specific travel reality. The Santander Aeromexico Platinum shines for Mexico-based travelers loyal to Aeromexico and SkyTeam, offering companion tickets, priority benefits and lounge access that directly improve common domestic and transborder routes. Its annual fee in pesos is manageable, especially with frequent promotions that reduce or waive the first year’s cost.

The Aeroplan Reserve, by contrast, is a premium, high-fee product intended for serious Air Canada and Star Alliance users. It rewards those who travel frequently through Canadian hubs, check bags often, and appreciate the comfort of Maple Leaf Lounges and partner lounges worldwide. Its ability to earn valuable Aeroplan points at accelerated rates on Air Canada purchases and key daily categories, combined with strong travel insurance and an annual worldwide companion pass, often makes it the more powerful choice for long-haul international travelers based in Canada.

If your life is centered in Mexico and Aeromexico is your default airline, Santander Aeromexico Platinum will likely feel more natural and useful day to day. If you live in Canada or regularly route yourself through Air Canada’s network and value global award flexibility, Aeroplan Reserve is the more compelling option. Some cross-border travelers may even find that holding both, each used strategically in its home ecosystem, yields the best of both worlds. Ultimately, the right decision is the one that aligns your card’s strengths with the way you actually travel, not just the perks that look attractive on paper.
