ATLANTA-<\/strong> Delta Air Lines (DL)<\/a> lost its antitrust immunity in a joint venture with Aeromexico on US-Mexico routes. This stems from a dispute over slot restrictions at Mexico City\u2019s Benito Ju\u00e1rez International Airport (MEX).<\/p>\n\n\n\n

The US Department of Transportation (DOT) ended the immunity due to anti-competitive practices favoring Aeromexico at the busy airport. Delta plans to review the decision while maintaining normal operations.<\/p>\n\n\n\n

Delta Loses Antitrust Immunity<\/h2>\n\n\n\n

The DOT determined that Mexico\u2019s slot allocation system at Benito Ju\u00e1rez International Airport placed US and other foreign carriers at a disadvantage.<\/p>\n\n\n\n

Aeromexico, which controls the majority of slots at MEX, retained a dominant position while competitors struggled to secure access.<\/p>\n\n\n\n

According to PYOK<\/a>, this imbalance prompted the DOT to act, removing the antitrust immunity that had previously allowed Delta and Aeromexico to coordinate pricing, schedules, and capacity.<\/p>\n\n\n\n

When the DOT first signaled its intent in July, the Mexican government responded with concessions. These included returning confiscated slots to US carriers in future scheduling seasons and creating a new regulator to manage allocations.<\/p>\n\n\n\n

However, the DOT concluded that these measures were incomplete, calling the matter an \u201cevolving situation\u201d with unresolved concerns.<\/p>\n\n\n\n

As a result, the DOT confirmed that antitrust immunity for the Delta\u2013Aeromexico alliance will be suspended effective January 1, 2026.<\/p>\n\n\n\n

Originally, the termination was set for October 2025, but regulators extended the deadline due to \u201cpractical challenges\u201d involved in dismantling the joint venture.<\/p>\n\n\n\n

Impact on Airlines and Travelers<\/h2>\n\n\n\n

For Delta, the ruling represents a setback in its transborder strategy. Without antitrust immunity, the carrier cannot fully integrate operations with Aeromexico, reducing efficiency on shared routes.<\/p>\n\n\n\n

Passengers may face fewer coordinated schedules, reduced connectivity, and potential fare impacts as competition dynamics shift.<\/p>\n\n\n\n

Delta voiced disappointment in the decision, stating it would \u201ccause significant harm to U.S. jobs, communities, and consumers traveling between the US and Mexico.\u201d<\/p>\n\n\n\n

The airline added that it is reviewing the order and considering next steps, while reassuring that all current flights will continue to operate normally.<\/p>\n\n\n\n

Aeromexico, meanwhile, maintains its strong presence at MEX. However, without the joint venture\u2019s legal protections, the partnership with Delta could lose competitiveness against other carriers serving US\u2013Mexico routes.<\/p>\n\n\n\n

Mexico City Airport\u2019s Chronic Capacity Challenges<\/h2>\n\n\n\n

Benito Ju\u00e1rez International Airport (MEX) has been operating beyond its designed capacity for years.<\/p>\n\n\n\n

To manage congestion, the Mexican government capped available slots and proposed shifting airline operations to secondary airports on the city\u2019s outskirts.<\/p>\n\n\n\n

These measures faced resistance, as most travelers prefer MEX for its central location and connectivity.<\/p>\n\n\n\n

Although large-scale improvement works were promised at MEX, they have yet to begin, leaving airlines restricted despite the absence of new infrastructure.<\/p>\n\n\n\n

This unresolved congestion remains a key factor in the DOT\u2019s frustration, as it directly impacts fair competition for US airlines.<\/p>\n\n\n\n

Broader Regulatory Context<\/h2>\n\n\n\n

The ruling underscores the US government\u2019s willingness to enforce competition under Open Skies agreements.<\/p>\n\n\n\n

By suspending Delta and Aeromexico\u2019s immunity, the DOT signaled it will not tolerate market imbalances that disproportionately benefit one carrier at the expense of rivals.<\/p>\n\n\n\n

The decision also raises broader questions about how Mexico manages its aviation infrastructure and whether promised reforms will materialize to ensure transparent slot allocation in the future.<\/p>\n\n\n\n
