A Mexican air traffic controllers’ union warned it could move toward a strike due to ongoing technical failures, staff shortages, and salary reductions that they say have affected operations for years. The Sindicato Nacional de Controladores de Tránsito Aéreo (Sinacta) stated that controllers have repeatedly alerted authorities about deteriorating systems and increasing operational risks, especially as Mexico prepares for higher international air traffic ahead of the 2026 World Cup.

Union representatives also claim salaries have fallen significantly compared to previous years, while staffing levels remain insufficient to handle current and future demand. The organization plans to present a formal labor complaint before federal authorities, raising concerns about possible disruptions to flight operations across the country if the conflict escalates.

Mexico’s aluminum industry expects the country to receive preferential treatment during the 2026 review of the United States Mexico Canada Agreement (T MEC), despite current U.S. tariffs on steel and aluminum. Eugenio Clariond Rangel, president of the Mexican Aluminum Institute (Imedal), stated that Mexico remains in a strong strategic position because of its integration with North American supply chains.

The sector opposes proposals that would require only primary aluminum produced within North America to qualify under T MEC rules of origin. Instead, the industry proposes allowing aluminum from “market economies” to qualify, arguing that stricter rules could reduce competitiveness for regional manufacturing.

Grupo Aeroportuario del Pacífico (GAP) announced the creation of an irrevocable administration and payment trust covering its 12 airport concessions in Mexico. The company said the structure is intended to strengthen its financial framework and support debt issuances, financing operations, and long term infrastructure investments tied to its airport expansion strategy.

The trust would include collection rights and operational revenue streams from airports such as Guadalajara, Tijuana, Los Cabos, and Puerto Vallarta. GAP stated the measure is part of its broader plan to support modernization and future development projects across its network.

The AFAC (Agencia Federal de Aviación Civil) announced that the Aeropuerto Internacional de la Ciudad de México will increase its operational capacity from 44 to 46 operations per hour during the 2026 summer season. The adjustment was authorized after technical evaluations carried out by the AFAC, SENEAM, and AICM, which determined that the airport has the operational conditions necessary to support the increase safely and efficiently.

According to the publication, the increase is related to improvements in operational procedures and airport infrastructure aimed at optimizing runway use and reducing occupancy times. Authorities stated that the new limit seeks to improve air connectivity and operational efficiency at Mexico’s busiest airport.

Mexico’s judicial reform is facing international scrutiny after complaints alleging violations of fundamental rights. The Inter-American Commission on Human Rights has requested information from the government, citing concerns over the dismissal of judges and potential impacts on labor protections, judicial independence, and legal certainty.

Legal challenges are ongoing both domestically and internationally, as critics argue the reform could weaken institutional checks and balances. The case is now drawing broader attention from global human rights bodies.

Oil shock fears are rising after the closure of the Strait of Hormuz, one of the world’s most critical routes for oil and gas exports. Governments have managed the first wave of disruption by releasing strategic reserves and paying higher prices to secure cargoes, but analysts warn that these emergency measures cannot be sustained for long. Markets remain under pressure as traders assess how long supply interruptions may continue.

If the blockage remains, countries could soon face a difficult decision: ration fuel consumption or allow gasoline and diesel prices to rise sharply for consumers. The impact would extend beyond gas stations, with higher shipping, aviation, and manufacturing costs adding fresh inflation pressure across the global economy and increasing uncertainty for businesses and households worldwide.

The Mexican Senate approved reforms granting new powers to the Federal Superior Audit Office (ASF), aiming to strengthen oversight of public resources and improve accountability. The changes would allow faster investigations, stronger enforcement tools, and broader access to information related to federal spending.

Supporters say the reform will help detect irregularities sooner and modernize the audit process. Critics are expected to watch how these expanded powers are applied in practice and whether they lead to real transparency improvements.

The Mexican Senate approved a reform allowing workers’ housing savings funds managed by institutions such as Workers’ National Housing Fund Institute (INFONAVIT) to be used for the construction and acquisition of housing projects. Supporters argue the measure will expand access to affordable homes, strengthen social housing policy, and address the country’s housing deficit.

Critics warn that using worker savings in this way could create risks over transparency, management, and long term protection of contributors’ funds. The reform now moves forward as one of the most debated housing policy changes in recent years.
