Four years after its launch, the joint venture between Delta Air Lines and LATAM has seen a 31% increase in capacity for 2026 compared to 2023. The two airlines say they transported 17.4 million passengers between October 2022 and July 2026 across 28 routes connecting North and South America. Their partnership includes not only flights but also passenger services and aircraft maintenance. The report, released on October 5, 2026, states that 83,000 flights were operated and 20.8 million seats were offered during the period. The 17.4 million passengers figure corresponds to this time frame, not a full four years of operations. The capacity growth compares 2026 to 2023, the first full year of the partnership. The joint venture, launched in October 2022 after approval from the U.S. Department of Transportation, allows Delta and LATAM to coordinate their schedules and capacities on shared markets. It goes beyond a basic code-sharing agreement, creating a unified offering between two complementary networks. The partnership now covers ten countries in North and South America, including the U.S., Canada, Argentina, Brazil, Chile, Colombia, Ecuador, Paraguay, Peru, and Uruguay. Ecuador joined in 2024, and Argentina in 2025, as the network expanded. This geographic growth has accompanied the expansion of the route network. Delta's vice president for Latin America and the Caribbean, Alex Antilla, noted in the October 5 statement that the joint venture has continued to grow and evolve over the past four years, strengthening connections between the two continents. He highlighted the increase in capacity, the expansion of the network, and the benefits for customers. The current network includes 28 routes, such as São Paulo–Los Angeles, Bogotá–Orlando, Guayaquil–New York, and Buenos Aires–Miami, offering more travel options between major South American cities and key North American hubs. However, the growth has not been uniform across all markets. In 2026, the combined capacity in Brazil was 33% higher than in 2023, 64% higher in Ecuador, and 25% higher in Peru. In Colombia and Chile, the increase was around 10%. Argentina, which joined the partnership in 2025, showed a nearly 47% increase in capacity compared to 2025. The expansion to Argentina was announced in April 2025 after obtaining the final regulatory approval. Delta emphasized that the partnership would also help strengthen freight services between Argentina, the U.S., and Canada by offering more transportation options and connections. For travelers, the partnership offers more than just additional flights. Members of Delta's SkyMiles and LATAM's LATAM Pass programs can accumulate miles or points on flights operated by either airline. Depending on their status and applicable conditions, they can enjoy benefits such as priority check-in, boarding, seat selection, and baggage services. Access to lounges is also subject to eligibility, including travel class, status, and loyalty program membership. The partners mention nearly 60 Delta Sky Clubs in the U.S., as well as LATAM lounges in Buenos Aires, Santiago, Lima, Bogotá, São Paulo, and Miami. These benefits do not automatically apply to all customers of the joint venture. The airlines also highlight features such as digital baggage tracking and the use of common terminals in key airports like São Paulo-Guarulhos, Santiago, and New York-JFK, which help make connecting journeys more efficient. Ramiro Alfonsin, LATAM Group's commercial director, stated in the same report that the joint venture has enabled the companies to offer more destinations and better connections by combining two complementary networks. In addition to the commercial partnership, Delta and LATAM have also formed an industrial collaboration. On April 21, 2026, Delta TechOps and LATAM Airlines Brasil announced an agreement to repair Airbus A320 components. This arrangement supports Delta's fleet and the needs of third-party airlines. The repairs are conducted at LATAM's maintenance center in São Carlos, Brazil, while Delta provides engineering standards and quality oversight. The project required regulatory approval in Brazil and was expected to start in the second quarter of 2026. The October report mentioned this cooperation but did not specify the actual deployment schedule or the status of the approval.
