Trump Administration Slams Mexico Over Air Transport Violations
As July 2025 draws to a close, US-Mexico relations are again in the spotlight—this time over a fierce aviation dispute that’s sending shockwaves through both the travel industry and diplomatic circles. The Trump administration, keeping its America First promise, has just unveiled sweeping new regulations on Mexican airlines operating in the United States, demanding unprecedented compliance after years of what officials describe as “blatant disregard” and “abuse” of a key bilateral aviation agreement. Among the strongest terms yet from Washington: all Mexican carriers must now obtain Department of Transportation (DOT) approval for flight schedules before setting foot—or wheel—on American soil, a move set to dramatically reshape cross-border air travel and trade.
This high-stakes move marks a clear response to what Transportation Secretary Sean Duffy (R) called years of “ongoing anti-competitive behavior” by Mexico. The core of the conflict is Mexico’s recent actions slashing US airline slots in Mexico City and forcibly relocating US cargo operations to distant airports, drawing fierce criticism from American officials and industry voices. For many conservative observers, these hardline steps are long overdue—America’s interests and businesses have paid the price for bureaucratic games south of the border, and decisive action sends a strong signal that fairness and reciprocity can no longer be ignored.
As Duffy emphasized, enough is enough: “Let these actions serve as a warning to any country who thinks it can take advantage of the US, our carriers, and our market. America First means fighting for the fundamental principle of fairness.” (US Department of Transportation). At stake is not only international airline competition but the very standards that keep the American aviation industry thriving. The DOT now requires all Mexican airlines to submit US-bound schedules directly, seeking explicit DOT approval for any large charter or regular flights.
“That ends today. Let these actions serve as a warning to any country who thinks it can take advantage of the US, our carriers, and our market. America First means fighting for the fundamental principle of fairness.” — Transportation Secretary Sean Duffy (R)
For businesses relying on cross-border shipping, American workers, and everyday travelers, this powerful intervention is seen by many as the clearest sign yet that under President Trump (R) and his conservative team, US interests are finally being put first again.
Details Unfold: Mexican Carriers Hit With Stringent Controls and Airline Alliances Face Turmoil
The dispute erupted after Mexico, starting in late 2022, began restricting coveted takeoff and landing slots at the already-congested Benito Juarez International Airport in Mexico City. Previously, under the landmark 2015 US-Mexico Air Transport Agreement, both US and Mexican carriers had a largely level playing field, able to operate freely between the two countries. All that changed when Mexico unilaterally reduced permitted flight slots per hour by nearly 20% in October 2023—dealing a blow to American airlines, including the nation’s largest, which depend on those slots to maintain critical commercial and supply-chain links.
Things escalated further in 2023 when the Mexican government forced all-cargo operations, overwhelmingly run by US companies, to relocate from centrally located Mexico City International Airport to Felipe Angeles International Airport—a facility more than 30 miles from the city, raising costs and complicating logistics. According to official US government documentation, these moves have already resulted in millions of dollars in added expenses and left some American businesses scrambling to adjust. (DOT statements)
“The DOT stated that Mexico has not complied with the bilateral air agreement since 2022 when it rescinded slots for U.S. carriers and then forced all-cargo carriers to relocate operations in 2023, which disrupted the market and increased costs for American businesses by millions of dollars.”
The new US countermeasures target these very practices—insisting Mexican airlines now file schedules for DOT review before getting greenlit for any large charter activity or scheduled flights into the US. In parallel, the Department’s “show-cause” order threatens the Delta–Aeromexico alliance, a joint venture between Delta Air Lines Inc. (DAL, R) and Grupo Aeromexico (AM, MX), which has been a major facilitator of coordinated pricing, capacity, and schedules since its 2016 inception.
If antitrust immunity is revoked, Delta and Aeromexico will no longer be permitted to coordinate on ticket prices, route planning, or revenue sharing for US–Mexico routes. This means not only competitive uncertainty for consumers and business travelers but also real risks of flight cancellations and raised costs.
“Delta and Aeromexico’s joint venture… is at risk of losing its antitrust immunity, which the airlines warn would cause significant harm to consumers, transborder competition, and thousands of travel plans.”
The DOT’s actions strike at the heart of what has become an unsustainable imbalance. While Mexican airlines were able to expand US-bound routes, Washington claims Mexico engineered systemic advantages by locking US companies out of prime Mexican infrastructure. Now the script is flipped, with Mexican airlines under the microscope and US leverage back in play. Delta and Aeromexico, for their part, argue that dissolving their partnership will damage travelers’ options, but for conservative policy thinkers, protecting American economic interests and restoring fair competition must come first.
Background: The 2015 Air Transport Agreement and America First Policy at Work
To fully grasp the current rift, it’s worth revisiting the hard-won 2015 US-Mexico Air Transport Agreement—once hailed as a major step forward for North American commerce. Signed under a more optimistic era, this agreement replaced a restrictive 1960s accord and aimed to spur growth on both sides of the border, opening skies to increased connectivity and healthy competition. The goal was straightforward: let airlines freely operate between any US and Mexican cities, expand choices, and strengthen supply chains for businesses and consumers alike.
The agreement guaranteed airlines “the right to fly between any city in Mexico and any in the United States,” a promise now at risk after Mexico’s recent moves.
But recent years saw that promise begin to fray. As Mexico cited airport “congestion” and construction to justify cutting US flight slots and shifting cargo operations far from Mexico City, US officials and businesses started sounding the alarm. The American Chamber of Commerce and major airline unions warned of mounting losses and a potentially dangerous precedent. If Mexico’s discriminatory practices went unchecked, the result could be spiraling costs, disrupted supply chains, and lasting damage to American commerce and jobs.
This is why the conservative response under President Trump (R) was both swift and decisive. From a policy standpoint, restoring leverage in international aviation is a crucial component of Trump’s broader “America First” agenda—one that puts American businesses, workers, and taxpayers ahead of unchecked foreign advantage. The current dispute underscores how crucial enforcement mechanisms in bilateral and trade agreements are—especially when dealing with partners who attempt to gain at America’s expense.
Negotiations continue behind the scenes, but with these stringent new regulations and the explicit threat to dismantle joint ventures that facilitate cross-border travel, the United States is asserting itself with clarity and confidence. For millions of travelers, logistics companies, and airlines on both sides of the border, the message is simple: The era of free passes for unfair practices is over. Under conservative leadership, America stands up for its own—at home and abroad.
“The DOT also highlighted Mexico’s failure to establish a transparent and non-discriminatory slot allocation system at its airports.”
Looking ahead, the Trump administration’s assertive response to Mexico’s aviation maneuvers will ripple through international negotiations well beyond US-Mexico borders. It’s a powerful reminder that in today’s world, only strong, clear-eyed action can ensure American prosperity and fairness on the global stage. And for conservative readers, it’s another chapter in the story of an America First agenda—undaunted and unapologetic.
