President Claudia Sheinbaum has introduced a broad electoral reform aimed at reducing political spending and reshaping Mexico’s legislative structure. The plan keeps the Chamber of Deputies at 500 members but modifies how proportional-representation seats are assigned, adds rules for gender balance and Mexicans abroad, and updates the selection system for senators while seeking a 25 percent cut in electoral costs across institutions, parties and tribunals.

The reform also proposes stricter financial oversight, eliminating cash contributions, regulating AI and social-media use in campaigns, expanding citizen-participation tools, and ending immediate consecutive reelection starting in 2030. It includes electronic voting options, fewer municipal council positions, and adjustments meant to centralize some electoral functions for efficiency. Supporters frame it as modernization, while critics warn it could weaken electoral autonomy.

Authorities in Jalisco lifted the Red Code after the violent events triggered by the presumed death of “El Mencho.” Both Guadalajara and Puerto Vallarta airports resumed operations with approximately ninety five percent of scheduled flights, according to airport operator GAP. Security protocols remain active as state forces continue monitoring and restoring normal mobility across the region.

Airport authorities confirmed that commercial flights, passenger areas and operational zones are functioning without major disruption. Travelers were advised to stay updated, although normal airport flow has largely resumed.

February 24 is celebrated as Mexico Flag Day in honor of the national emblem adopted in 1937, a symbol that reflects the country’s identity and its historical struggle for sovereignty. The green represents hope and the aspirations of the nation, the white stands for unity and the pursuit of peace, and the red honors the courage and sacrifice of those who fought for independence. Today the flag remains one of the most powerful national symbols, recognized for its deep cultural significance and its role in shaping Mexico’s modern identity.

Renovation works at Mexico City International Airport (AICM) have reached 40 percent completion, according to the Navy Ministry and the airport operator Grupo Aeroportuario Marina. As part of this progress, authorities inaugurated four remodeled areas across Terminal 1 and Terminal 2, introducing updated passenger spaces equipped with modern technology and improvements aimed at enhancing safety and traveler experience. 

The reopening included the new South B Hall in Terminal 1 (about 2,000 m² with capacity for 626 passengers), renovated facades and baggage claim areas at gates 1 to 3, and upgraded waiting rooms near gates 12 and 13. Officials highlighted that the ongoing works are crucial for bolstering operational efficiency and managing both domestic and international traffic. Ahead of the 2026 FIFA World Cup, the comprehensive modernization effort continues while the airport remains fully operational.

An internal review revealed that Mexico City International Airport has continued applying the same airport service tariffs to airlines that were established in 2010. These charges cover key operational services such as landing, aircraft parking, and overnight stays. Despite inflation and market adjustments over the past fifteen years, the rates have not been updated, creating a significant pricing gap compared to other major airports in Mexico.

Airports in Cancún, Guadalajara, and Monterrey currently charge substantially higher fees, in some cases more than triple the rates still in place at AICM. The report warns that maintaining outdated tariffs limits revenue generation and weakens the airport’s financial competitiveness within the national airport system.

The Mexican Senate approved a constitutional reform to gradually reduce the legal workweek from 48 to 40 hours, with a phased implementation expected between 2027 and 2030. The measure is considered one of the most significant labor changes in recent decades and seeks to modernize Mexico’s work framework while maintaining full pay for workers during the transition. Lawmakers supporting the reform argue it aligns the country more closely with international standards and responds to long standing demands to reduce excessive working hours.

However, the approved text does not constitutionally guarantee two weekly rest days, meaning the traditional structure of six working days with one mandatory day off remains in place. This omission has sparked criticism from opposition legislators and labor groups, who argue that without explicitly establishing a five day workweek, the reform falls short of delivering a structural shift in workers’ rest rights. The debate now centers on how the change will be regulated in secondary laws and how businesses will adapt to the gradual reduction.

The Aeropuerto Internacional de la Ciudad de México (AICM) and Aeropuerto Internacional Felipe Ángeles (AIFA) updated their Tarifa de Uso de Aeropuerto (TUA) for February 2026. At the AICM, the national passenger fee will be 525 pesos, lowered from 537.22 pesos in January, while the international fee will be 996.79 pesos, down from 1,020 pesos. 

At AIFA, the national TUA remains 266.62 pesos (unchanged from January), and the international TUA is 470.55 pesos (slightly lower than January’s 481.51 pesos). The TUA is a mandatory charge applied to passengers for using airport facilities and varies depending on the airport and whether the flight is domestic or international.

Aviation specialists are urging that Airport Use Fee TUA revenues be returned directly to Mexico City International Airport AICM so the airport can fund essential maintenance and recover operational capacity. Today nearly all TUA income is diverted to the Texcoco cancellation bond trust, leaving AICM without the resources needed to maintain infrastructure under rising demand.

Although part of the debt has been repurchased, AICM remains obligated to long term bond payments until at least 2047. This forces the airport to rely mainly on commercial operations and airline service fees, leaving minimal funds for urgent repairs. Redirecting TUA back to AICM is described as the only viable path to stabilize and prevent further deterioration.
