A 1944 treaty still prevents most foreign airlines from flying domestic routes

Under Article 7 of the 1944 Chicago Convention, a country may reserve domestic air services to its own carriers. In practice, that means Qantas cannot sell and operate a New York–Los Angeles flight, and Emirates cannot run a Paris–Nice hop.

The two major exceptions are the European Union’s single aviation market and the Australia–New Zealand Trans-Tasman arrangement, where regionally licensed airlines do hold domestic traffic rights.

On 7 December 1944, while the war still raged, 52 delegations gathered in the Stevens Hotel ballroom in Chicago and signed the Convention on International Civil Aviation. One winter day of diplomatic engineering still controls what appears on your travel booking screen eight decades later.

That rule is cabotage: a state’s right to keep foreign airlines off routes between two points inside its own borders. Article 7 of the Convention gives every signatory the power to refuse that kind of carriage. Most still do. The result is a quiet line drawn through the global booking map — one you hit the moment you try to put Qantas on a New York–Los Angeles itinerary or Emirates on Paris–Nice.

There are two big carve-outs. The European Union has effectively erased the line among its own member states. Australia and New Zealand did something similar across the Tasman. The rest of the world still lives with the line — and increasingly tests it.

The 1944 compromise that still controls your booking options

On paper, the Convention on International Civil Aviation does three things at once. Article 1 confirms each state’s complete and exclusive sovereignty over its airspace. Article 7 then hands states a domestic protection tool: the right to refuse a foreign carrier the carriage of passengers, cargo or mail between points within its borders. Cabotage is the word for it, borrowed from maritime law.

The way the drafters wrote Article 7 is telling. It also stops a state from handing an exclusive cabotage privilege to any single foreign airline, however friendly. The restriction was a compromise: protect national carriers from foreign competition, but keep international travel flowing. The text drew a boundary around its own scope, too. Civil aircraft only — state and military machines were left outside.

That same Convention created the International Civil Aviation Organization, the permanent body that still manages the standards behind international flying. But the cabotage wall built in Chicago is what quietly governs your booking screen today.

What a $125,000 fine looks like in practice

Ask a gate agent and you will get one answer. Ask the Department of Transportation and you get a consent order. In 2018, DOT signed one with Qantas Airways over carriage the agency called unauthorized cabotage. The carrier had sold and flown revenue passengers on its own aircraft between New York JFK and Los Angeles in 2015 and 2016 — domestic legs that only connected them to partner flights abroad afterward. The penalty was $125,000, plus a cease-and-desist order.

The line DOT drew matters. Marketing a domestic U.S. sector on another airline’s plane through a codeshare is generally tolerated. Crossing the line means operating the domestic leg yourself under a foreign air operator certificate. Qantas stepped over it. The takeaway for alliance members: a joint venture with an American carrier does not buy the right to fly Americans between American cities.

The two exceptions — and where the wall still stands

The modern test of Article 7 is whether a region can make its internal routes look domestic to the right set of airlines. Europe has done it most completely. Regulation (EC) No 1008/2008, the common rules for running air services, defines a Community air carrier as an airline holding a Member State licence, with substantial ownership and effective control in EU states or their nationals. Article 15 then grants those carriers the right to operate intra-Community air services without extra permits — and says any restrictions from older bilateral deals between member states are superseded. In plain terms, according to Legislation.gov.uk, a Spanish-licensed airline may run domestic flights wholly inside Germany without asking Berlin.

But Europe is not the only place that happened. Since 1996, the Trans-Tasman Single Aviation Market has let Australian and New Zealand airlines operate domestic and trans-Tasman routes in either country as if the two formed one market. A 2002 open skies agreement formalized and expanded those rights. Once more, a foreign-registered carrier holds a legal right to carry purely internal traffic inside the other state.

Cabotage status and legal basis in selected aviation markets
Market Foreign airline allowed to operate domestic routes? Primary legal basis or policy Concrete example or note
European Union / EEA Yes, for EU-licensed Community air carriers; foreign non-EU carriers generally no Regulation (EC) No 1008/2008, Article 15 on intra-Community air services An Irish-licensed EU carrier may operate domestic flights entirely within Spain under EU single aviation market rules.
Australia–New Zealand (Trans-Tasman Single Aviation Market) Yes, for Australian and New Zealand airlines meeting SAM conditions 1996 SAM arrangements, formalised by the 2002 open skies agreement A New Zealand airline can operate a domestic route wholly within Australia under SAM, subject to safety approvals.
United States No, cabotage generally prohibited for foreign airlines 49 U.S.C. cabotage provisions; DOT consent orders used for violations Qantas fined $125,000 in 2018 for carrying local passengers between New York and Los Angeles.
Canada No, foreign carriers barred from internal point-to-point services Canada Transportation Act and bilateral agreements preserve cabotage for Canadian carriers Cannot sell standalone domestic segments such as Toronto–Vancouver. (unverified)
China No, domestic air services reserved to Chinese-licensed carriers Chinese civil aviation regulations and bilateral agreements restrict domestic routes to Chinese carriers Cannot sell purely domestic itineraries such as Beijing–Shanghai. (unverified)
India No, foreign airlines cannot operate wholly domestic scheduled routes Indian bilateral agreements and policy papers emphasise cabotage restrictions on domestic flights Cannot run domestic sectors such as Delhi–Mumbai. (unverified)
Japan No, cabotage restricted to Japanese carriers Japan’s air services regime maintains domestic traffic rights for Japanese carriers only Cannot routinely carry passengers solely between Tokyo and Osaka. (unverified)
Brazil No, with limited liberalisation for foreign investment but not full cabotage Brazilian aviation law allows foreign ownership in airlines but retains cabotage limits Cannot themselves operate domestic-only routes like São Paulo–Rio de Janeiro. (unverified)
United Arab Emirates No, domestic cabotage reserved for UAE-licensed airlines UAE civil aviation regulations focus foreign carriers on international services Do not operate domestic-only services between UAE cities. (unverified)
Active liberalisation debate market (ASEAN Single Aviation Market) Partial – regional liberalisation under discussion but cabotage not fully opened ASEAN Single Aviation Market initiatives and community carrier proposals Community carrier model discussed, but full domestic cabotage not yet implemented.

ASEAN occupies a space between the exceptions and the rule. Regional policy papers under the single-aviation-market agenda sketch an “ASEAN community carrier” model: majority ownership spread across several member states, relaxed effective-control tests, one country keeping regulatory oversight. That would lay groundwork for regional traffic rights beyond classic bilateral cabotage limits. But no fully functioning legal instrument has opened domestic services across all member states yet. For now, it is a blueprint, not a booking reality.

For Canada, China, India, Japan, Brazil and the UAE, official material confirms the restriction: foreign airlines fly international routes, while domestic point-to-point services stay with locally licensed carriers. The table above flags those rows as unverified because this session could not locate a precise statutory clause for each.

Why the line between marketing and operating matters

The line that keeps enforcement honest is the one between selling a flight and flying it. A codeshare lets an alliance member put its own flight number on another airline’s metal. That is virtual cabotage — the seat is marketed, but the operating carrier is domestic, so no Article 7 problem. The problem starts when a foreign airline operates the domestic sector under its own certificate.

That is exactly what Qantas did between JFK and LAX, and why the cease-and-desist order was about carriage, not marketing. Airlines read the European arrangement the same way: once a carrier crosses into operating a purely domestic leg under a foreign certificate, it leaves the legal shelter that marketing-only setups provide. A Community air carrier licence is the key that unlocks intra-bloc domestic rights; a codeshare alone does not.

The 1996 Trans-Tasman arrangement produces the same logic across the Tasman: a licensed SAM carrier operates as if Australia and New Zealand were a single country. That is the exception that proves how high the wall remains everywhere else.

What this means for you

For a traveler, the cabotage wall explains most of the friction in booking options. If you cannot find a pure domestic itinerary on a foreign carrier, that is not a missing partnership. It is a legal boundary the operating carrier cannot cross.

Frequent flyer members feel it in two versions. An alliance itinerary between, say, Chicago and Sydney puts the U.S. domestic leg on an American carrier, not the Australian one — even when the whole ticket carries a Qantas flight number. The miles and the lounge access may look seamless; the metal changes at the border.

The direction is one-way: technical liberalization, not repeal. Europe and the Tasman show what regional choice looks like. ASEAN’s community-carrier blueprint is the next test. Watch the proposals, not press releases.

Questions? Answers.

Can foreign airlines fly domestic routes?

No, with two major exceptions. U.S. law generally prohibits foreign airlines from carrying passengers between two U.S. points for compensation. Inside the European Union, EU-licensed Community air carriers may operate intra-Community domestic flights under Regulation (EC) No 1008/2008, and the Trans-Tasman Single Aviation Market gives Australian and New Zealand carriers the same right in either country.

How does the EU allow a foreign airline to operate domestic flights inside another member state?

Regulation (EC) No 1008/2008 defines a Community air carrier as one holding a Member State licence, with substantial ownership and effective control tied to EU states or nationals. Article 15 grants those carriers the right to operate intra-Community air services without extra permits and supersedes any older bilateral restrictions between member states.

What exactly did Qantas do to trigger a U.S. cabotage fine, and how much was it?

Qantas sold and carried revenue passengers on its own aircraft between New York JFK and Los Angeles in 2015 and 2016, connecting them to international partner flights afterward. The U.S. Department of Transportation fined Qantas $125,000 in a 2018 consent order and imposed a cease-and-desist requirement.

What is the status of cabotage liberalization in ASEAN?

ASEAN has not yet introduced a legal instrument granting unrestricted domestic cabotage across all member states. Policy papers propose an ASEAN community carrier model in which majority ownership could spread among member states while one country keeps regulatory oversight — a blueprint rather than an implemented right.
