Cabotage in aviation is the rule that stops a foreign airline from carrying paying passengers or cargo between two points inside another country. A French carrier cannot sell tickets on a New York–Los Angeles flight; a Japanese carrier cannot fly paying passengers from Chicago to Miami. The restriction traces to the 1944 Chicago Convention and appears in the law of nearly every country, which makes it one of the most consistent rules in international aviation.
The Chicago Convention Rule
The legal foundation is Article 7 of the Convention on International Civil Aviation, signed in Chicago in 1944. It gives every signatory the right to refuse permission for foreign aircraft to pick up passengers, mail, or cargo within its borders when those passengers or goods are headed to another point in the same country.1International Civil Aviation Organization. Convention on International Civil Aviation
The prohibition targets commercial operations where payment is involved. A foreign-registered private plane carrying its owner between two domestic cities with no money changing hands generally falls outside the rule, though some countries restrict even non-revenue flights by foreign aircraft.2Aircraft Owners and Pilots Association.

Article 7 also contains an anti-exclusivity clause. Countries agree not to grant cabotage privileges on an exclusive basis to any single foreign nation or airline. A country could, in theory, open its domestic market to foreign carriers, but it cannot hand that access to one country’s airlines while shutting the rest out.3United Nations Treaty Series. Convention on International Civil Aviation
Where Cabotage Fits Among the Freedoms of the Air
International traffic rights are organized into nine “freedoms of the air,” a framework developed through ICAO. The first five are common and cover things like overflying a foreign country, making a technical stop for fuel, and carrying passengers between the airline’s home country and another country. The higher freedoms are rarer and more politically sensitive.
Cabotage sits at the eighth and ninth freedoms. The eighth, consecutive cabotage, would let a foreign airline operate a domestic leg within another country as part of a route that starts in the airline’s home country. A German carrier flying Frankfurt–New York and then continuing New York–Chicago with paying passengers on the domestic segment is the textbook example. The ninth, stand-alone cabotage, goes further and would let that same German carrier operate New York–Chicago with no connection to a Frankfurt flight at all. Almost no country grants either freedom, so both remain largely theoretical outside a few exceptions.
How the United States Enforces It
The United States runs one of the strictest cabotage regimes anywhere. Under 49 U.S.C. § 41703, foreign civil aircraft are prohibited from picking up passengers or cargo for compensation at one U.S. location and delivering them to another U.S. location.4Office of the Law Revision Counsel. 49 US Code 41703 – Navigation of Foreign Civil Aircraft The Department of Transportation reads the prohibition narrowly and enforces it strictly.5U.S. Department of Transportation. What Is Cabotage in Aviation and How Does It Work
The statute carves out only two narrow exceptions. The Secretary of Transportation can authorize domestic transport by foreign aircraft under emergency conditions through 49 U.S.C. § 40109(g). The other exception lets U.S. airlines use foreign-registered aircraft on domestic routes under a dry lease, meaning the aircraft comes without crew and the U.S. airline operates it with its own pilots under its own certificate.4Office of the Law Revision Counsel. 49 US Code 41703 – Navigation of Foreign Civil Aircraft Outside those two situations, the ban is absolute.
Wet Leases Are Blocked, Code-Sharing Is Not
Wet leasing, where one airline rents out an aircraft along with its crew, has been used elsewhere to sidestep cabotage. U.S. rules close that door. Under 14 CFR § 119.53(b), a U.S. certificate holder cannot wet-lease an aircraft from a foreign carrier or any other foreign person not authorized to engage in common carriage.6eCFR. 14 CFR 119.53 – Wet Leasing of Aircraft and Other Arrangements for Transportation by Air
Code-sharing works differently. When a foreign airline puts its flight code on a domestic U.S. route, the U.S. carrier is still the one operating the aircraft with its own crew under its own certificate. The foreign carrier sells the ticket and passengers see its branding, but the transport itself is domestic. Because a U.S. carrier performs the flight, code-sharing does not violate cabotage rules.
Ownership Rules That Back the Restriction
Cabotage sits alongside strict ownership requirements for U.S. airlines. To hold a U.S. airline certificate, at least 75% of voting equity and 51% of non-voting equity must be held by U.S. citizens, and U.S. nationals must effectively control the airline. Together with the cabotage prohibition, those requirements keep domestic air travel both operated and owned by Americans.
Open Skies Agreements Do Not Grant Cabotage
Since 1992, the United States has pursued Open Skies agreements aimed at reducing government involvement in airline decisions about routes, capacity, and pricing on international flights.7U.S. Department of Transportation. Air Service Agreements They liberalize international travel, but they draw a hard line at domestic markets. The U.S. model Open Skies text states plainly that nothing in the agreement gives a foreign airline the right to pick up passengers or cargo in U.S. territory that are destined for another point in U.S. territory.8U.S. Department of State. Current Model Open Skies Agreement Text
Older bilateral air service agreements are more restrictive still. They typically spell out specific routes, frequencies, and capacity between the two nations, and they preserve cabotage protections. Modern Open Skies or traditional bilateral, domestic routes stay off the table.
The EU Single Aviation Market
The European Union is the significant exception. Under Regulation (EC) No. 1008/2008, any EU-licensed air carrier is entitled to operate air services within the entire Community, including domestic routes inside other member states.9EUR-Lex. Regulation 1008/2008 An Irish airline can fly passengers between Rome and Milan just as freely as an Italian one. Once a carrier holds an operating license in any member state, the whole EU market is open to it. That approach works because member states agreed to pool sovereignty over aviation as part of a broader economic union, and no comparable arrangement exists elsewhere.
Penalties for Violations
Enforcement is real. In the United States, U.S. Customs and Border Protection watches for violations and reports them to DOT headquarters.10eCFR. 19 CFR 122.165 – Air Cabotage In one action, the DOT ordered a Canadian charter air taxi to cease and desist from future violations and assessed a $20,000 civil penalty for transporting passengers between two U.S. points.11U.S. Department of Transportation. Department of Transportation Order 2011-6-19 – Cameron Air Services Inc
In some jurisdictions the consequences go beyond money. Customs authorities in the EU and Canada have the power to seize aircraft when cabotage violations are confirmed.2Aircraft Owners and Pilots Association. Cabotage in Aviation Enforcement varies widely by country, from little practical restriction in some to zero tolerance in others, so operators of private and charter aircraft flying internationally need to check each country’s specific rules before carrying passengers between domestic points.
