FAA coordination – As SpaceX ramps up Starship activity, the FAA is increasingly managing air-traffic hazards that spill beyond U.S. borders—adding pressure to coordinate with Mexico and parts of the Caribbean, and heightening disruption risk for airlines and passengers when lau
For pilots flying across the Caribbean, the sky is getting more crowded—not just with aircraft, but with rocket deadlines.
Starship launches from the United States can affect aircraft routes over Canada. Mexico. and the Caribbean. because SpaceX vehicles sometimes travel through monitored airspace or risk shedding debris. Those concerns pile on top of other objections raised in those countries. including claims about damage to local fish populations and reports of rocket parts washing ashore.
Behind the scenes, the Federal Aviation Administration has been building procedures to keep commercial flights moving while launches happen. New letters of agreement obtained by Fast Company show the FAA’s expanded. operational workload—and a hard reality: not every country is included in the preparations on the same terms.
The documents detail what SpaceX was required to communicate to FAA air traffic control before a launch. They also show how the FAA communicates with air traffic controllers about potential mishaps, and what that coordination can look like when the risk area crosses international boundaries.
One FAA letter of agreement governing SpaceX Starship launches from Boca Chica, Texas—at the mouth of the Rio Grande and close to the Mexican border—includes Mexico as a party and references numerous Mexican air navigation officials. Mexico’s presence reflects where launches are expected to travel.
But no Caribbean country is mentioned in that same letter. even though debris from Starship launches has sometimes dispersed over the region’s airspace. When asked about the omission. the FAA pointed to federal launch license requirements and said “[a]greements exist between FAA’s ATO Space Operations. SpaceX. and foreign entities in compliance with this requirement.” (ATO stands for Air Traffic Organization. the FAA’s operational arm.).
In comments on the matter. the FAA said preparations for a Starship launch begin months in advance and emphasized that the agency works with air traffic organizations in other countries. Before a launch. it said a space operations team assesses how the mission could affect airspace by factoring in the proposed launch window. the planned flight trajectory. a flight safety analysis. and prior flight history. The FAA also develops a temporary hazard area.
Once those steps are completed, the FAA said it distributes an airspace management plan to its own air traffic control facilities and to international air traffic control offices abroad, in a process that involves collaboration with the State Department.
“The FAA continues to work to improve the safe and efficient integration of space operations into the U.S. airspace system,” an agency spokesperson said. “With the commercial space industry growing at record pace. rockets launch multiple times a week and no public injuries or fatalities have occurred during any of the more than 1. 150 FAA-licensed or permitted commercial space launch and reentry operations.”.
Still, disruption is showing up for travelers and airlines.
At least one Starship mishap has forced flights to divert from their planned trajectories. And the FAA’s coordination challenge appears poised to intensify as SpaceX pushes toward making Starship a reliable “workhorse” vehicle—something the company says depends on continuing to receive launch approvals from the FAA. SpaceX, which is preparing for an upcoming IPO, did not respond to a request for comment.
The FAA’s structure is built for both aviation safety and launch timing. The Office of Commercial Space Transportation approves the licenses companies need to send vehicles into space when launching from the United States. The Air Traffic Organization manages airspace and clears launches to proceed at a given time.
To prepare for individual events. space companies sign letters of agreement with the ATO that establish procedures for monitoring a launch. A 2022 agreement covering SpaceX’s Starship and Super Heavy launches from Boca Chica—obtained by Fast Company—details preparations for both launches and booster returns and shows how many groups are involved in prelaunch discussions. Those include multiple U.S. air traffic control centers and Mexico’s air navigation agency.
Kelvin Coleman, a former director of the Office of Commercial Space Transportation (known as AST from a previous name), said countries like Mexico are included when flights are expected to pass through their airspace.
The FAA says coordination happens well before liftoff. Its air traffic office engages early with affected U.S. facilities and foreign air navigation providers and holds three or four premission briefings to discuss potential hazard areas and traffic plans. Pilots. however. typically receive notice only a few days in advance. according to the Air Line Pilots Association. even when launches can force flights to adjust routes many miles off course.
Just before liftoff. the FAA opens a real-time hotline with the launch company. and that line stays active until the rocket hardware is either in orbit or back on Earth. If something goes wrong. SpaceX is supposed to relay the vehicle’s last known position. projected debris path. and expected impact areas as quickly as possible. The FAA can then close airspace, reroute planes, hold flights on the ground, and coordinate with U.S. and foreign air traffic authorities.
These precautions help explain why a launch can still create measurable pressure across the region’s flight network.
FAA environmental reviews note that some Starship launches. if they occur during periods of high traffic. could theoretically disrupt as many as 200 flights per hour. One southerly trajectory used by the company stands to impact airspace not just over Mexico. but also Cuba. Jamaica. and the Cayman Islands—countries that FAA documents note are expected to close their airspace.
The practical effect can arrive fast for passengers.
A Starship test last month, for example, served as a reminder that launches reverberate beyond the closure zone. An FAA advisory noted that Miami air traffic control warned that flights looking to avoid the closed-off flight area would not be allowed into foreign airspace and would need to “hold” until the airspace became “cold and traversable.” Another notice said that. should the launch fail. hazard and debris impact areas could be activated across the airspace surrounding Santo Domingo in the Dominican Republic.
In advance of that launch, The Gleaner, Jamaica’s national newspaper, quoted the country’s aviation authority as warning that airspace could be limited. The air traffic authority of the Cayman Islands similarly flagged airspace closures in a social media post.
The launch was successful, but several flights appear to have been affected. One JetBlue flight that was on its way to Jamaica was diverted back to Fort Lauderdale, Florida.
“Last-minute adjustments to a debris area or unplanned weather during a launch can cause flight diversions and refueling stops. ” a JetBlue spokesperson said. “While we do all we can to plan ahead and minimize operational impacts. these events can lead to customer disruption. longer travel times. and increased operating costs.”.
For airlines, planning is uneven across routes. Fast Company had reached out to about 20 airlines that sometimes fly routes through the Caribbean to ask how they prepare for Starship launches; most did not reply. Delta and Southwest emphasized their work with the FAA and their focus on safety.
The stakes become sharper when a launch fails.
In January 2025, a Starship rocket exploded during a test launch and sprayed debris across the region’s airspace. Pilots flying across the region could see rocket parts flaming down from their cockpit windows. Some scrambled to avoid the debris path, a Wall Street Journal and ProPublica later reported. The FAA subsequently issued a broad safety notice emphasizing the risk rocket launches can pose to flights and expanded the hazard areas it closes off for launches.
After that mishap. Coleman said. AST had a series of conversations with leaders from places like the Bahamas and the Turks and Caicos Islands. which pushed for more insight into how they might be affected by future accidents. Yet those countries were never integrated into the earlier agreement. Coleman said, “That’s a good question.”.
“The Air Traffic Organization has done a pretty good job in trying to manage those conversations,” Coleman said. “But. you know. given the amount of conversations that need to occur and the amount of coordination that needs to happen… It’s become something that I think the agency is taking a real close look at to see if there can be enhanced ways to move forward that don’t require as much labor on the part of the Air Traffic Organization.”.
There is a growing sense, built from letters of agreement and flight advisories alike, that the FAA is no longer only clearing space for launches in U.S. skies. It is now trying to keep commercial aviation functioning across a web of jurisdictions—while the rocket industry’s cadence quickens.

So the FAA has to negotiate with other countries now? Wild.
I swear every time Starship launches my flight app acts weird like it knows. So they’re basically closing sky lanes for a rocket schedule? Cool cool.
Wait, they’re coordinating with Mexico and the Caribbean but Canada too? That sounds like they’re just throwing darts at a map. Also fish populations getting damaged?? Like one launch can do that, or is that just something people keep repeating.
This is what happens when billionaires rush deadlines. If debris is washing ashore then why are we even pretending it’s “procedures” and “letters of agreement” and not just cleanup and liability. Also I read somewhere pilots are gonna have to reroute over Canada and Mexico, but is that permanent or just during launch windows? Either way airlines will blame it on “coordination” and passengers pay.
