US Mexico Aviation Dispute Eases with Slot Restoration at AICM
Mexico agrees to return flight slots to U.S. carriers at AICM, resolving a major air travel dispute and ensuring better cooperation in 2026.
The skies between the United States and Mexico are clearing up after a period of significant turbulence. At the heart of the issue lies access to Mexico City’s Benito Juárez International Airport (AICM), the country’s busiest and most congested air hub. For months, a dispute over flight slots, the designated times airlines are permitted to take off or land, has strained aviation relations, impacting major carriers on both sides of the border and leaving travelers caught in the middle. The core of the conflict stemmed from a unilateral decision by Mexican authorities to reduce the number of operations at AICM to alleviate congestion, a move that directly affected U.S. airlines and was viewed by the U.S. Department of Transportation (DOT) as a violation of the existing air transport agreement.
This wasn’t just a simple scheduling disagreement; it was a complex issue with significant economic and logistical implications. The reduction in slots forced airlines like American, Delta, and United to scale back their services, disrupting established routes and limiting options for passengers. In response, the U.S. DOT took retaliatory measures, revoking approvals for new routes requested by Mexican carriers. The situation highlighted the delicate balance of international aviation agreements and the critical importance of airport access in maintaining a competitive and open market for air travel. The recent announcement by Mexican President Claudia Sheinbaum that slots will be returned to U.S. carriers marks a pivotal moment in de-escalating this tension and restoring a sense of normalcy to one of the world’s busiest international air corridors.
The resolution, however, introduces new dynamics, particularly with the involvement of Mexicana, Mexico’s state-run airline. The decision for Mexicana to hand over some of its own slots at AICM to U.S. carriers is a significant gesture. It not only paves the way for the restoration of previously cut services but also signals a renewed commitment to cooperation. As we unpack the layers of this dispute, from its origins in airport congestion to its resolution through diplomatic and regulatory channels, it becomes clear that the path forward involves not just returning to the status quo but also establishing a more transparent and equitable system for managing airport capacity in the future.
The dispute traces its origins back to 2022, when Mexican aviation authorities initiated measures to address long-standing congestion issues at AICM. The airport, a critical hub for Latin America, was struggling to handle its volume of traffic. Initially, the government mandated a reduction in hourly flight movements from 61 to 52. This was later followed by a more drastic cut, bringing the number down to 43 operations per hour. The official justification for these reductions was the need to ease operational pressure and facilitate construction work. However, critics pointed out that the promised construction never materialized, leading to suspicions that the move was also intended to encourage airlines to shift their operations to the newer, but more distant, Felipe Angeles International Airport (AIFA).
This reduction had an immediate and direct impact on both Mexican and U.S. airlines. Carriers like Aeromexico, Viva Aerobus, and Volaris, alongside their American counterparts, American Airlines, Delta Air Lines, and United Airlines, were forced to adjust their schedules and, in some cases, cancel routes. The U.S. Department of Transportation (DOT) argued that these actions were not in line with the U.S.-Mexico air transport agreement, which is designed to ensure fair and equal opportunity for airlines from both nations to compete. The DOT’s stance was that any changes to slot allocations should be made through a transparent and mutually agreed-upon process, not by unilateral decree.
The situation escalated as the U.S. government responded with its own set of measures. In a clear signal of its disapproval, the DOT revoked its approval for more than a dozen routes that had been requested by Mexican carriers. This retaliatory action effectively froze expansion plans for Mexican carriers into the U.S. market, creating a stalemate that benefited neither side. The standoff underscored the interconnectedness of the two countries’ aviation markets and the potential for significant disruption when international agreements are perceived to be violated. It became evident that a resolution would require not just a reversal of the slot cuts but a renewed commitment to the principles of the bilateral agreement.
The core of the story is the ongoing tension and recent de-escalation between Mexico and the U.S. over aviation rights and airport access.
The turning point in the dispute came through a series of discussions and commitments between Mexican and U.S. officials. In October 2025, the Mexican government formally pledged to return the slots that had been taken from U.S. carriers. This commitment was a crucial first step, although the U.S. DOT noted at the time that the implementation of this promise was still pending. The breakthrough was further solidified in November 2025, when President Claudia Sheinbaum announced that the state-run airline, Mexicana, would facilitate the process by handing over some of its own slots at AICM to the affected U.S. airlines. While the exact number of slots was not specified, the announcement was a clear and public signal of Mexico’s intent to resolve the issue.
This resolution is not just about restoring the previous flight schedules; it’s also about establishing a more stable and transparent framework for the future. As part of the agreement, Mexico has pledged to adopt an international reference system for slot allocation beginning in 2026. This move is aimed at improving transparency and ensuring that the process for assigning take-off and landing times is fair and in line with global best practices. For U.S. airlines, this means a more predictable operating environment and a reduced risk of similar disputes arising in the future. According to the DOT, the restoration of these slots could allow U.S. carriers to resume their full services by the summer 2026 season. The involvement of Mexicana, the recently revived state-owned airline, adds an interesting dimension to the resolution. By ceding some of its valuable slots at the capital’s main airport, the Mexican government is demonstrating a tangible commitment to making things right. This move also subtly addresses the underlying issue of capacity at AICM and the government’s broader strategy for its aviation sector, which includes promoting AIFA as a viable alternative. The resolution, therefore, represents a multi-faceted approach that addresses the immediate concerns of U.S. carriers while also laying the groundwork for a more sustainable and cooperative aviation relationship moving forward.
The resolution of the flight slot dispute between Mexico and the United States marks a significant step toward normalizing relations in one of North America’s most vital aviation markets. The agreement to return slots to U.S. carriers at AICM not only restores critical air connectivity but also reaffirms the importance of adhering to bilateral agreements that ensure fairness and reciprocity. For travelers, this de-escalation is welcome news, as it promises the return of more direct flights, increased competition, and potentially more stable pricing. The episode serves as a case study in international aviation diplomacy, demonstrating how disagreements over airport access can escalate into broader trade tensions and how dialogue and a commitment to established standards are essential for their resolution.
Looking to the future, the commitment by Mexico to adopt an international system for slot allocation by 2026 is perhaps the most significant long-term outcome of this dispute. This move toward greater transparency and standardized procedures should help prevent similar conflicts from arising in the future. It provides a clearer framework for all airlines operating in Mexico and strengthens the foundation of the U.S.-Mexico air transport agreement. As the aviation industry continues to recover and grow, the ability to manage capacity at key hubs like AICM in a fair and efficient manner will be crucial for sustaining a healthy and competitive market that benefits airlines and consumers alike.

Tennessee Bill Proposes State Control Over Major Airport Boards
Senate Bill 2473 aims to transfer majority control of Tennessee’s major airport boards from local to state officials, restructuring governance and financial powers.
This article summarizes reporting by Local Memphis. Additional context is provided via comprehensive legislative research.
Tennessee state lawmakers are moving forward with legislation that would transfer majority control of the state’s major metropolitan and regional Airports boards from local municipalities to state officials. According to reporting by Local Memphis, Senate Bill 2473 advanced on Wednesday, March 25, 2026, setting the stage for a significant shift in aviation governance across the state.
The bill, sponsored by Senator Paul Bailey and House Speaker Cameron Sexton, targets the current boards of several major airports, including the Memphis-Shelby County Airport Authority. If passed, the legislation would vacate these locally appointed bodies, allowing state lawmakers and the governor to appoint the majority of the new board members.
Legislative research indicates that Senate Bill 2473 and its House companion, House Bill 2507, would standardize airport governance by replacing existing authorities with a uniform nine-member commission. Under this new structure, state officials would hold the power to appoint six of the nine members. Specifically, the Governor, the House Speaker, and the Senate Speaker would each be granted two appointments. Local officials, such as city mayors, would be left to appoint the remaining three members.
The legislation also introduces strict eligibility requirements. According to the provided legislative context, the bill explicitly prohibits police officers, city or county employees, and individuals with financial stakes in the airport from serving on these newly formed boards.
In addition to restructuring the boards, a companion measure is reportedly advancing that would alter the financial operations of these airports. This measure would allow airports in Memphis, Chattanooga, and the Tri-Cities to borrow money or issue bonds independently, removing the current requirement for approval from local municipal leadership.
To understand the current legislative push, we must look back at a similar effort in 2023. State lawmakers previously passed a law aimed at vacating the Metro Nashville Airport Authority to replace it with a state-appointed board. However, Metro Nashville successfully sued the state, arguing that the legislation violated the “Home Rule” amendment of the Tennessee Constitution, which protects local governments from targeted state legislation without local consent.
In October 2023, a three-judge panel ruled the state’s takeover unconstitutional, noting that the law specifically targeted Nashville while intentionally excluding Memphis, home to the world’s busiest cargo airport. This ruling was unanimously upheld by a state appeals court in April 2025. By expanding the scope of Senate Bill 2473 to include all major metropolitan and regional airports across Tennessee, including Nashville, Memphis, Knoxville, Chattanooga, and the Tri-Cities, lawmakers are actively attempting to bypass the legal hurdles that defeated their 2023 effort. Applying the law statewide is a strategic move designed to make the bill more defensible against future constitutional challenges.
If enacted, the bill will drastically alter the governance of several major economic hubs. For example, the Memphis-Shelby County Airport Authority is currently governed by a seven-member board, with five members appointed by the Memphis Mayor and two by the Shelby County Mayor. As reported by Local Memphis, the new bill would strip local leaders of this majority control. Similarly, the Tri-Cities Airport Authority, currently a 12-member board with diverse municipal and county representation, would be reduced to nine members, leaving only three local seats and forcing current city employees to vacate their positions.
Proponents of the bill, including House Speaker Cameron Sexton, argue that the state invests significantly more tax revenue into these regional airports than local municipal governments do. They contend that because these airports serve populations far beyond a single city’s limits, having board members from outside the immediate local area is beneficial and justifies proportional state representation.
Conversely, local officials and Democratic lawmakers argue that municipal representatives are better equipped to understand the specific needs of the communities these airports serve. Opponents express deep concern that shifting control to state politicians will heavily politicize boards that are currently functioning effectively and maintaining strong financial positions.
During the Senate Transportation and Safety Committee meeting on March 25, 2026, Senator Heidi Campbell (D-Nashville) was the sole dissenting vote against recommending the bill. Highlighting the likelihood of inevitable, multi-year legal battles, Campbell criticized the legislation:
“[This bill will create a] big mess.”
We observe that the ongoing tension between state and local authorities over infrastructure control is not unique to Tennessee, but the aggressive legislative maneuvering here highlights a significant shift in aviation governance. While standardizing board structures and granting financial autonomy could streamline certain statewide transportation goals, the abrupt removal of local institutional knowledge poses a risk to operational continuity. Furthermore, despite the state’s attempt to circumvent the “Home Rule” amendment by broadening the bill’s scope, the forced restructuring of highly localized assets like the Memphis-Shelby County Airport Authority is highly likely to trigger a new wave of complex constitutional litigation.
Senate Bill 2473 is a piece of Tennessee legislation that would vacate current local airport authority boards and replace them with a nine-member commission, where the majority of members (six) are appointed by state officials rather than local municipalities.
The bill targets major metropolitan and regional airports across Tennessee, including those in Memphis, Nashville, Knoxville, Chattanooga, and the Tri-Cities. State lawmakers argue that because the state provides significant tax revenue to these regional assets, it should have proportional representation on their governing boards. Opponents argue it is an overreach that strips local communities of control over their own infrastructure.

Alstom to Upgrade Houston Airport Skyway with New Vehicles and Tech
Alstom will modernize Houston’s Skyway with 16 new vehicles, Urbalis control tech, and a 15-year maintenance contract valued at €380 million.
This article is based on an official press release from Alstom.
Alstom has announced a major agreement to overhaul the automated people mover (APM) system at George Bush Intercontinental Airport (IAH) in Houston, Texas. According to an official company press release, the €380 million ($437 million) contract includes comprehensive upgrades to the airport’s Skyway system and a 15-year extension for operations and maintenance services.
The modernization effort comes as the Houston airport undergoes a multi-billion-dollar expansion to handle surging traveler volumes, which exceeded 48 million passengers last year. We note that this infrastructure investment aims to minimize service disruptions and improve passenger flow between terminals during peak demand.
Under the terms of the agreement, Alstom will deliver 16 new Innovia APM R vehicles to replace the aging fleet. The company stated in its release that the project also involves constructing a new Operations Control Center and upgrading the system’s communications and automatic train control technologies to the Urbalis platform.
Additionally, station doors across all terminals will be replaced to facilitate safer and faster boarding. To minimize the impact on travelers while the Skyway is out of service for these upgrades, interim busing will be provided, according to the announcement.
Beyond the hardware and software improvements, the contract secures Alstom’s role in operating and maintaining the Skyway for another 15 years. The manufacturer noted that a dedicated 48-person on-site team will manage the system’s daily reliability.
Alstom has managed the Skyway APM for two decades using the original Innovia APM 100 vehicles. The company highlighted its strong operational track record at the airport, reporting a 99.63% availability rate for the current system in 2024.
“Modernizing Houston’s Skyway system is essential to meeting the needs of one of the fastest-growing airports in the United States. This next-generation APM will deliver more reliable, seamless travel for millions of passengers every year.”
The Houston contract builds upon Alstom’s extensive footprint in the automated transit market. According to the press release, the company’s Innovia APM systems are currently utilized at 15 different airports across the United States. Globally, the manufacturer has delivered over 30 automated people mover systems. Furthermore, the integration of the Urbalis automatic train control system at IAH reflects a wider deployment of this technology. The company noted that its Urbalis signaling system is active on more than 190 metro lines across 32 countries, with 74 of those lines operating on a completely automatic, driverless basis. As a major supplier in the U.S. market, Alstom reports having delivered over 12,000 new or renovated vehicles for various domestic rail agencies and airports.
We view this contract as a significant reinforcement of Alstom’s footprint in the United States transit and aviation sectors. By securing both the capital upgrade and a 15-year maintenance agreement, the company ensures a steady, long-term revenue stream while locking in its proprietary technology at a major international hub. The transition to the new Innovia APM R vehicles and the Urbalis signaling system aligns with broader industry trends toward fully automated, high-capacity airport transit solutions capable of handling record-breaking passenger growth.
The contract is valued at approximately €380 million, or $437 million, according to the manufacturer’s press release.
Alstom will deploy 16 new Innovia APM R vehicles as part of the Skyway upgrade.

Chase Field Industrial Airport Gains Texas Aviation System Designation
Chase Field Industrial Airport in Beeville, Texas, secures Texas Airport System Plan inclusion, unlocking state funding for maintenance and upgrades.
This article is based on an official press release from the Bee Development Authority.
On March 24, 2026, the Bee Development Authority (BDA) announced that the Chase Field Industrial Airport Complex (FAA LID: TX2) in Beeville, Texas, has been officially accepted into the Texas Airport System Plan (TASP) by the Texas Department of Transportation (TxDOT). This milestone designation recognizes the facility as a vital component of the state’s aviation infrastructure.
According to the BDA’s official press release, this designation unlocks the first state or federal funding contribution for the facility since the closure of Naval Air Station (NAS) Chase Field in 1993. The inclusion provides the airport with critical financial support, including reimbursements for annual maintenance and access to matching grants for major capital improvements.
The 1,850-acre complex, located approximately five miles southeast of Beeville in Bee County, is strategically positioned to leverage this new funding. The BDA stated that the financial backing will help attract aerospace, advanced manufacturing, and maintenance, repair, and overhaul (MRO) operations to South Texas, ultimately driving regional job creation and economic development.
Administered by the TxDOT Aviation Division, the TASP identifies airports that play an essential role in the economic and social development of Texas. According to supplementary research data provided alongside the release, out of over 1,600 landing facilities in the state, only about 292 airports meet the stringent requirements for inclusion in the plan. This selective inclusion minimizes the duplication of facilities and concentrates public financial resources where they are most effective.
Acceptance into the TASP makes Chase Field eligible for TxDOT’s Routine Airport Maintenance Program (RAMP). The BDA notes this program will provide critical reimbursements for approximately $100,000 in annual maintenance costs at the airfield. Furthermore, the airport gains access to the Aviation Capital Improvement Program (ACIP) and Aviation Facilities Development Program (AFDP). These programs offer 90/10 matching grants, meaning the state or federal government covers 90 percent of the cost while the local sponsor covers 10 percent, empowering the BDA to undertake major infrastructure upgrades.
“This acceptance into the Texas Airport System Plan marks the first federal or state funding contribution to the Bee Development Authority since the closure of Naval Air Station Chase Field in 1993. The state funds will now provide critical reimbursements for approximately $100,000 of annual maintenance costs at the airfield, as well as grant eligibility for 90/10 matching programs on Capital Improvement Projects, empowering the BDA to build new facilities and drive meaningful economic growth for Bee County and South Texas.”, Orlando Vasquez, BDA Board Chair
The site has a rich military history. Originally leased in 1943 as a municipal airport, it was commissioned by the U.S. Navy to train pilots during World War II. It was recommissioned in 1954 for jet training and upgraded to a full Naval Air Station in 1968. Historical data indicates that during its peak, the base trained approximately one-third of all U.S. Navy pilots serving in the Vietnam War. Following a recommendation by the 1991 Base Realignment and Closure (BRAC) Commission, NAS Chase Field officially closed in 1993, resulting in the loss of thousands of jobs in Bee County.
Established in 2001 under Texas state legislation, the BDA was tasked with managing and redeveloping the former military installation. Today, the public-use airport features heavy-duty military-grade infrastructure. Facility specifications highlight an 8,000-foot lighted runway, over 500,000 square feet of concrete tarmac, two 90,000-square-foot hangars, a 30,000-square-foot warehouse, and a state-of-the-art paint booth. The facility was officially designated as a Public-Use Airport by the FAA and TxDOT in May 2016. “Acceptance into the Texas Airport System Plan is a significant step forward for Chase Field and the broader Beeville and Bee County community. This recognition from TxDOT validates our ongoing efforts to reposition this former naval air station as a modern, high-capacity aviation and industrial asset.”, Michael Blair, BDA Executive Director
The BDA credited state legislative delegation members for their advocacy in achieving this administrative recognition. State Senator Adam Hinojosa (District 27) and State Representative J.M. Lozano (District 43) worked closely with the BDA and TxDOT to advance the airport’s inclusion in the TASP, highlighting its strategic importance to the region.
In the press release, Senator Hinojosa described the inclusion as a “major win for our region” that will unlock new opportunities for prosperity in Beeville and surrounding communities. Representative Lozano echoed this sentiment, affirming Chase Field’s strategic value and expressing a commitment to securing resources to transform the site into a hub for aerospace and advanced industries.
At AirPro News, we view the successful transition of former military bases into civilian industrial hubs as a proven economic development strategy. Chase Field has previously demonstrated this potential; historical data shows it hosted defense contractors Kay and Associates and Sikorsky for helicopter MRO operations, employing up to 347 skilled aviation professionals until 2012.
With its existing heavy-duty infrastructure and new access to state funding for modernization, Chase Field is highly competitive for companies seeking “site-ready” locations. The TASP designation serves as a strong signal to private investors and aerospace companies that the state of Texas recognizes and financially backs the long-term viability of the airport. Proximity to major logistics hubs, including the Port of Corpus Christi (57 miles away) and San Antonio (100 miles away), further bolsters its appeal for industrial expansion.
Administered by the TxDOT Aviation Division, the TASP identifies airports that play an essential role in the economic and social development of Texas. Inclusion in the plan makes airports eligible for specific state and federal funding programs.
Through TxDOT’s Routine Airport Maintenance Program (RAMP), the airport is eligible for reimbursements covering approximately $100,000 in annual maintenance costs. It also gains access to 90/10 matching grants for major capital improvements.
NAS Chase Field officially closed in 1993 following a recommendation by the 1991 Base Realignment and Closure (BRAC) Commission.
