The United States has revoked 13 routes operated by Mexican airlines, and Mexican President Claudia Sheinbaum says she disagrees with the decision.

The revocation is the hardest fact in a story that touches two governments, a bilateral aviation agreement, and a Mexican carrier market still working its way back from a regulatory downgrade that froze its US expansion for more than two years.

What exactly happened?

Washington pulled 13 routes serving Mexican airlines. The precise mechanics — which authority issued the action, which carriers lost which city pairs, and the effective dates — sit with the US and Mexican transport agencies, and the details were still circulating through official channels as the news broke.

What is confirmed is the scale and the response. Thirteen routes is not a rounding error. In a market where Mexican operators have been clawing back US market share, a withdrawal of that size bites directly into network planning, aircraft allocation, and slot positions that carriers may not easily recover.

Sheinbaum, speaking publicly on the decision, made her position plain: she disagrees with it. Her statement signals that the matter has moved beyond aviation regulators and into the diplomatic channel, where aviation disputes between the two countries have landed before.

Why does this matter beyond the 13 routes?

The US–Mexico market is one of the largest bilateral air travel markets in the world by passenger volume. Any restriction on one side invites scrutiny of the other, and carriers on both sides of the border watch these decisions closely because capacity in this market is governed by a negotiated agreement, not open competition.

For Mexican airlines, the stakes are concrete. Routes lost mean:

• Revenue gone from high-traffic cross-border city pairs
• Aircraft and crews that must be redeployed, often to thinner, lower-yield markets
• Slot and gate positions at US airports that competitors can absorb

For US carriers, a competitor's loss can open room to add frequencies — provided their own authorities and fleet plans allow it.

What is the history here?

The revocation lands on scar tissue. In 2021, the US Federal Aviation Administration downgraded Mexico's safety rating to Category 2 under its International Aviation Safety Assessment program, a move that barred Mexican carriers from adding new US service and forced code-share restructuring. Mexico regained Category 1 status in 2023, and its carriers have been rebuilding their US footprints since.

Against that backdrop, any fresh US restriction on Mexican airline routes reads as more than a routine administrative action. It raises the question of whether the two countries' aviation relationship is stabilizing or fracturing again.

Sheinbaum's disagreement, stated openly, suggests Mexico intends to contest the action rather than absorb it quietly. Whether that means formal consultations under the bilateral air transport agreement, a negotiated rollback, or a prolonged dispute depends on the responses from both transport ministries in the coming weeks.

Airlines, lessors, and airport operators on both sides of the border will be watching the next government-to-government exchange before pricing the impact — because in this market, 13 routes can move fare structures, fleet plans, and diplomatic calendars all at once.
