LATAM Pass - How One Airline Built a Loyalty Empire Across an Entire Continent

LATAM Pass has grown into one of the most powerful airline loyalty programs in the world - not primarily because of marketing, but because of geography, a landmark continental merger, and a co-branded credit card strategy that embeds the program into everyday consumer spending. Understanding how this happened reveals a great deal about how aviation economics work at continental scale.

Why South American Geography Makes Aviation Essential Infrastructure

South America stretches more than 4,000 miles from the Caribbean coast of Colombia to Tierra del Fuego, within a few hundred miles of Antarctica. The Andes mountain range runs the entire length of the western continent. The Amazon basin fills the interior with jungle and river systems that make road and rail connections between major cities not just inconvenient, but in many cases genuinely impractical.

This means flying in South America is not a luxury. It is infrastructure.

Brazil alone has a population of over 210 million people and is the fifth-largest country on Earth by land area. The distance from São Paulo to Manaus - both within Brazil - is roughly equivalent to flying from New York to Denver. There is no practical overland alternative. That context is essential for understanding the scale of LATAM’s loyalty numbers.

How Two Airlines Became One: The LAN-TAM Merger

LATAM Airlines Group was not founded as a single carrier. It was built through one of the most consequential mergers in commercial aviation history.

LAN Airlines, founded in Chile in 1929, spent decades establishing dominance across the western edge of the continent - Chile, Peru, Colombia, Ecuador, and Argentina. LAN operated a primary hub at Santiago’s Arturo Merino Benítez International Airport and held membership in the oneworld alliance alongside American Airlines and British Airways, giving it strong reach into international markets.

TAM Airlines grew into Brazil’s largest carrier. As the dominant airline in the largest country in South America - a country where aviation is essential infrastructure - TAM’s scale was formidable. Its base at São Paulo’s Guarulhos International Airport positioned it as the gateway carrier for one of the largest economies in the Southern Hemisphere. TAM’s loyalty program, Multiplus, had already accumulated massive membership before any merger discussions began.

The combination of LAN and TAM was announced in 2012 and finalized over the following years. LAN’s program (LANPASS) and TAM’s Multiplus were integrated over time into what is now called LATAM Pass. When you merge the two dominant carriers in their respective markets and consolidate their loyalty bases, the membership math scales rapidly.

The Credit Card Strategy That Drives Everyday Enrollment

A merger alone does not explain the program’s depth. The more underappreciated driver is co-branded credit cards - a mechanism that North American aviation observers sometimes discount when looking at South American programs.

In Brazil and Chile, co-branded cards that earn airline miles are not niche products for road warriors. They are mainstream consumer financial products. Millions of cardholders earn LATAM Pass miles on groceries, utilities, fuel, and restaurant meals - every day, whether or not a flight is on the calendar. This is precisely the model that transformed American AAdvantage and United MileagePlus into financial powerhouses in North America, and LATAM replicated it across South America with significant success.

The practical result: loyalty program membership grows in proportion to the financial system, not just to travel volume. The program functions as a consumer financial product first, and an airline reward second.

Network Coverage Across the Continent

LATAM operates more than 140 destinations, with comprehensive coverage across Brazil, Chile, Peru, Colombia, Ecuador, Bolivia, Paraguay, and Uruguay. International routes connect South America to North America, Europe, and the Caribbean.

For many routes within the continent, LATAM is not one option among several - it is the primary option, and in some markets the only viable one. This reflects the capital and operational commitment required to build reliable infrastructure across terrain as challenging as the Andes and the Amazon. It is not a product of anti-competitive behavior; it is the result of sustained investment where others have not committed.

For the frequent traveler based in Santiago or São Paulo, LATAM Pass membership is effectively not optional. The question is not whether to join - it is how many miles you have accumulated.

The Delta Partnership and International Reach

Delta Air Lines made a significant equity investment in LATAM Airlines Group as part of a strategic partnership and joint business agreement announced in 2019. The deal gave LATAM stronger connections into Delta’s North American network and gave Delta a meaningful foothold in South America.

For LATAM Pass members, the partnership expanded earn-and-redeem opportunities across a wider international network - making the program more attractive to internationally mobile travelers and driving further enrollment.

Pandemic, Bankruptcy, and Recovery

LATAM, like carriers around the world, faced severe financial stress during the pandemic. The airline filed for Chapter 11 bankruptcy protection in the United States in 2020. The restructuring was complex, but LATAM emerged from bankruptcy in 2022 with its network largely intact and its loyalty program operational.

The loyalty program itself proved to be a significant financial asset through that period. The revenue generated by selling miles to banks and card partners, and the miles liability on the books, represents a real business with independent value - separate from seat count on any given flight. This mirrors a pattern seen globally: major loyalty programs have become, in many respects, the most financially resilient component of the airline business. American Airlines’ AAdvantage program has been used as collateral for debt financing. LATAM Pass is structured the same way. The membership numbers are not a marketing statistic - they represent a financial ecosystem.

What This Means for Pilots Operating in South America

For pilots planning operations into South America, LATAM’s network architecture has practical implications beyond frequent flyer points.

Santiago and São Paulo are the two primary hub connection points. Lima’s Jorge Chávez International Airport functions as an important secondary hub, particularly for routes along the Pacific coast. Cities that LATAM serves heavily tend to have better airport services, customs and immigration processing, fuel availability, and general aviation support - because commercial and general aviation infrastructure tend to develop together.

For general aviation pilots considering ferry flights or aircraft positioning south through Central America and into South America, LATAM’s coverage map is a reasonable proxy for where robust airport infrastructure exists on the continent.

Key Takeaways

LATAM Airlines Group was formed through the 2012 merger of LAN (Chile) and TAM (Brazil), combining the dominant carriers on opposite sides of the continent into a single entity.
South American geography - the Andes, the Amazon basin, vast distances - makes commercial aviation essential infrastructure, not a discretionary service, which underpins LATAM’s scale.
Co-branded credit card partnerships in Brazil and Chile drive daily mile accrual for millions of members who may not fly frequently, making LATAM Pass a consumer financial product as much as a travel reward.
LATAM filed for Chapter 11 bankruptcy in 2020 and emerged in 2022 with its network and loyalty program intact; the program’s value as a financial asset aided the restructuring.
A strategic equity partnership with Delta Air Lines, announced in 2019, extended LATAM Pass earn-and-redeem reach into North America.
South America is one of the fastest-growing aviation markets in the world; LATAM is positioned as the dominant network carrier as the continent’s middle class and travel demand continue to expand.
