Mexico City’s main airport increased its passenger usage fee, known as TUA, starting April 1, 2026, making air travel slightly more expensive. The adjustment raises the domestic fee by about 2.9% to roughly $542 MXN (30.59 USD), while international flights increase by about 3% to around $1,030 MXN (58.09 USD). This charge is automatically included in airline ticket prices and can represent a significant portion of the total cost.

The increase follows a regulated annual update tied to inflation indicators in the United States and comes as the airport undergoes renovations ahead of the 2026 World Cup. Authorities note that the TUA helps fund airport operations, maintenance, and infrastructure improvements, meaning passengers indirectly contribute to ongoing upgrades when purchasing tickets.

Travelers using Mexico City’s main airport are facing major disruptions during the busy Holy Week holiday due to ongoing renovation works. Passengers report navigating through construction zones filled with dust, scaffolding, machinery, and restricted areas across both terminals, as over a thousand workers operate around the clock to upgrade the facilities ahead of the 2026 FIFA World Cup.

Although authorities say the project is about 65% complete and will be finished by mid-May, the timing has caused frustration among travelers dealing with reduced space, delays, and limited services during one of the year’s peak travel periods. Improvements include upgrades to restrooms, waiting areas, security filters, and infrastructure, but the ongoing works continue to impact passenger mobility and overall airport experience.

Mexico’s recent tariff increases on imports from China are now affecting more than $30 billion worth of Chinese exports, according to China’s Ministry of Commerce. The measures, which include tariffs of up to 35% on goods from countries without free trade agreements, are being viewed by Beijing as significant trade barriers.

China estimates potential losses of around $9.4 billion, with the automotive, mechanical, and electrical sectors among the most impacted. Mexico was China’s largest vehicle export market in 2025, raising tensions as Beijing signals possible retaliation.

Oil prices surged to around $113 per barrel after escalating tensions between the United States and Iran, centered on the Strait of Hormuz, a critical global oil transit route. Former President Donald Trump issued an ultimatum demanding Iran fully reopen the strait within 48 hours, warning of potential military consequences if ignored.

The situation has intensified following threats, attacks on vessels, and disruptions to shipping in the region, raising fears of a supply shock. Markets reacted sharply due to the strategic importance of the strait, through which a significant portion of the world’s oil supply flows. Analysts warn that prolonged instability could push prices even higher and trigger broader economic consequences globally.

The U.S. Secretary of Energy, Chris Wright, confirmed that the United States has no plans to ban oil and gas exports, dismissing speculation that such a measure could be used to control rising domestic fuel prices. The statement comes amid global energy market instability driven by the ongoing conflict in the Middle East and disruptions in key supply routes like the Strait of Hormuz.

Officials emphasized that the U.S. remains the world’s leading producer and exporter of energy, reinforcing its position as a net energy exporter. Despite concerns over increasing gasoline prices, the government argues that restricting exports would not be an effective solution, as fuel prices are largely determined by global markets.

Ride-hailing platforms in Mexico are urging authorities to establish clear regulations that allow them to operate in airports ahead of the 2026 FIFA World Cup. They argue that current restrictions limit efficiency and could negatively impact mobility as the country prepares to receive a surge of international visitors.

At the same time, traditional airport taxi operators oppose these changes, warning about unfair competition and legal concerns. The growing tension between both sides highlights the urgency for the government to define rules that balance competition, service quality, and logistics before the global event.

Mexico has unveiled a national air defense strategy to secure its airspace during the 2026 FIFA World Cup, when the country will host matches in Mexico City, Guadalajara, and Monterrey. The plan establishes a multilayer surveillance system designed to monitor and control air activity around stadiums, airports, and other critical infrastructure during the tournament.

Authorities will implement five layers of airspace control, coordinated by the Mexican Armed Forces through national surveillance centers. The system will combine radar monitoring, military aircraft, interceptor capable training jets, drones, and anti drone technology. Temporary restricted airspace zones will also be created near venues to prevent unauthorized flights and ensure rapid response to any aerial security threat.

Airspace closures across the Middle East have significantly disrupted global aviation following a sharp military escalation involving the United States, Israel, and Iran. The crisis began after joint U.S. and Israeli strikes against Iranian targets triggered retaliatory missile and drone attacks across several countries in the region. Due to the security risk, multiple governments restricted or closed their airspace, forcing airlines to cancel flights or reroute aircraft away from one of the world’s most important aviation corridors.

The disruption has grounded thousands of flights and stranded hundreds of thousands of travelers while major aviation hubs such as Dubai, Doha, and Abu Dhabi temporarily reduced or suspended operations. Airlines worldwide are now redirecting routes through longer corridors, increasing fuel consumption and operational costs while governments coordinate evacuation and repatriation flights for citizens affected by the crisis.
