Codified Freedoms

9 Freedoms

1 to 5 treaty, 6 to 9 common law

Foundational Treaty

1944

Chicago Convention (ICAO)

Most Coveted Right

5th Freedom

Beyond traffic rights

FREEDOM 1

First Freedom of the Air (Overflight Rights)

Technical Right

In plain English: Flying through another country sky on the way to somewhere else without touching down.

ICAO Legal Definition:

The right of an airline to fly across the airspace of a foreign country without landing there.

Visual Flight Path Diagram

Traffic Carried: Passengers traveling from Country A to Country C.

Famous Real-World Airline Examples

British Airways London (LHR) to New York (JFK)

Flies through Irish and Canadian airspace under First Freedom overflight agreements before entering United States airspace.

Lufthansa Frankfurt (FRA) to Tokyo (HND)

Historically overflew Siberian airspace (Russia) under lucrative bilateral First Freedom overflight royalty fees.

Diplomatic & Legal Context:

Formulated in the International Air Services Transit Agreement (IASTA). Airspace overflight closures (such as current Russian or Ukrainian airspace restrictions) force airlines to make multi-hour detours burning tons of additional fuel.

FREEDOM 2

Second Freedom of the Air (Technical Refueling Stop)

Technical Right

In plain English: Landing purely for fuel or maintenance, with no passengers allowed to get on or off.

ICAO Legal Definition:

The right of an airline to land in a foreign country for non-traffic purposes, such as emergency repairs or refueling, without taking on or discharging commercial passengers or cargo.

Visual Flight Path Diagram

Traffic Carried: Only passengers on through-tickets between Country A and Country C. No local ticket sales in Country B.

Famous Real-World Airline Examples

Qantas Perth (PER) to London (LHR) via Singapore (SIN) or Darwin

During seasonal headwinds or payload limits, aircraft make a technical fuel-only stop without commercial local embarkation.

Aer Lingus Shannon (SNN) Transatlantic Gateway

In the early piston propeller and early jet era, Shannon Airport in Ireland and Gander in Newfoundland served as the world premier transatlantic technical refueling stations.

Diplomatic & Legal Context:

Second Freedom stops allow transoceanic flights to operate safely beyond normal non-stop aircraft range limits, without competing against local domestic carriers.

FREEDOM 3

Third Freedom of the Air (Outbound Commercial Service)

Commercial Right

In plain English: Flying paying passengers from your home country to another foreign nation.

ICAO Legal Definition:

The right of an airline to carry revenue passengers, mail, and cargo from its home country to a foreign country.

Visual Flight Path Diagram

Traffic Carried: Outbound traffic originating in Country A ending in Country B.

Famous Real-World Airline Examples

Delta Air Lines Atlanta (ATL) to London (LHR)

Delta transports US and international passengers embarking in Atlanta to London Heathrow.

Singapore Airlines Singapore (SIN) to Sydney (SYD)

Singapore Airlines carries commercial travelers departing Singapore to Australia.

Diplomatic & Legal Context:

The Third Freedom is the foundation of modern international airline schedules, granted almost universally in bilateral air service treaties alongside the Fourth Freedom.

FREEDOM 4

Fourth Freedom of the Air (Inbound Commercial Service)

Commercial Right

In plain English: Flying paying passengers from a foreign country back home to your own nation.

ICAO Legal Definition:

The right of an airline to carry revenue passengers, mail, and cargo from a foreign country back to its home country.

Visual Flight Path Diagram

Traffic Carried: Inbound traffic originating in Country B ending in Country A.

Famous Real-World Airline Examples

British Airways New York (JFK) to London (LHR)

British Airways takes on commercial passengers in New York and flies them home to the United Kingdom.

Emirates Paris (CDG) to Dubai (DXB)

Emirates carries passengers embarking in France back home to its hub in the United Arab Emirates.

Diplomatic & Legal Context:

The Third and Fourth Freedoms operate as an inseparable reciprocal pair in international aviation diplomacy: an airline cannot fly outbound without the legal right to carry traffic home.

FREEDOM 5

Fifth Freedom of the Air (Beyond Rights)

Beyond Right

In plain English: Flying between two foreign nations and selling local tickets between them, on a route that touches your home country.

ICAO Legal Definition:

The right of an airline to carry revenue traffic between two foreign countries on a flight that originates or terminates in its own home country.

Visual Flight Path Diagram

Traffic Carried: Local passengers boarding in Country B and disembarking in Country C, alongside through passengers from Country A.

Famous Real-World Airline Examples

Singapore Airlines Singapore (SIN) to Frankfurt (FRA) to New York (JFK)

Flight SQ26 lands in Frankfurt where German and European passengers can purchase tickets to fly purely between Frankfurt and New York on Singapore Airlines.

Emirates Dubai (DXB) to Milan (MXP) to New York (JFK)

Emirates flies passengers purely between Milan, Italy and New York on an A380 or 777 as part of a service originating in Dubai.

Diplomatic & Legal Context:

Fifth Freedom rights are fiercely negotiated because they allow foreign carriers to compete directly against domestic airlines on their flagship international routes.

FREEDOM 6

Sixth Freedom of the Air (Hub Connecting Service)

Beyond Right

In plain English: Taking passengers between two foreign countries by giving them a transfer connection at your own home hub.

ICAO Legal Definition:

The right of an airline to carry passengers or cargo between two foreign countries by connecting them through its own home country hub.

Visual Flight Path Diagram

Traffic Carried: Passengers traveling from Country B to Country C with a scheduled plane change at Country A.

Famous Real-World Airline Examples

Qatar Airways London (LHR) to Doha (DOH) to Sydney (SYD)

Transports British travelers to Australia by connecting them through Hamad International Airport in Qatar.

Turkish Airlines New York (JFK) to Istanbul (IST) to Nairobi (NBO)

Flies Americans to sub-Saharan Africa via its mega-hub in Istanbul, connecting 120+ countries worldwide.

Diplomatic & Legal Context:

The Sixth Freedom is legally a commercial combination of Fourth and Third freedom rights. It forms the business model of global super-connector airlines in the Persian Gulf, Turkey, Iceland, and Ethiopia.

FREEDOM 7

Seventh Freedom of the Air (Standalone Foreign Service)

Beyond Right

In plain English: Operating international flights between two foreign countries without your planes ever visiting your home country on that route.

ICAO Legal Definition:

The right of an airline to operate scheduled commercial flights between two foreign countries without any connection to or origin in its home country.

Visual Flight Path Diagram

Traffic Carried: International passengers traveling between two foreign nations on a foreign-registered aircraft.

Famous Real-World Airline Examples

Ryanair Madrid (MAD, Spain) to Rome (FCO, Italy)

Irish-registered airline Ryanair bases aircraft in Spain and flies daily scheduled international passenger flights to Italy without visiting Ireland.

FedEx Express Paris (CDG) to Frankfurt (FRA) or Dubai (DXB)

US cargo giant FedEx operates dedicated European and Asian intra-continental feeder flights under specialized 7th Freedom cargo grants.

Diplomatic & Legal Context:

Largely restricted in passenger aviation outside deeply integrated multilateral blocs like the European Union Single Aviation Market or Open Skies cargo accords.

FREEDOM 8

Eighth Freedom of the Air (Consecutive Cabotage)

Cabotage Right

In plain English: Picking up domestic passengers within another country as an extension tag of an international flight from home.

ICAO Legal Definition:

The right of an airline to carry passengers between two domestic points in a foreign country on a flight that originates or terminates in its home country.

Visual Flight Path Diagram

Traffic Carried: Domestic Country B passengers along the second domestic flight leg.

Famous Real-World Airline Examples

Air New Zealand Auckland (AKL) to Los Angeles (LAX) to Chicago (ORD)

Under hypothetical 8th Freedom, an international flight from Auckland could pick up American travelers in Los Angeles and let them fly to Chicago. (In practice, strictly banned by US law).

Qantas Auckland to Christchurch tag within New Zealand

Under the Australia-New Zealand Single Aviation Market Agreement, Australian carriers enjoy reciprocal consecutive cabotage rights in New Zealand.

Diplomatic & Legal Context:

Article 7 of the Chicago Convention explicitly allows countries to refuse cabotage permissions, and virtually all major aviation nations (including the US) rigorously protect domestic airlines against foreign competition.

FREEDOM 9

Ninth Freedom of the Air (Standalone Stand-Alone Cabotage)

Cabotage Right

In plain English: Flying purely domestic flights inside another country with no connection whatsoever to your home nation.

ICAO Legal Definition:

The right of an airline to operate domestic scheduled passenger flights entirely within a foreign country without originating or continuing to its home country.

Famous Real-World Airline Examples

easyJet Milan (MXP) to Naples (NAP) within Italy

British/Austrian airline easyJet operates pure domestic Italian flights under the European Common Aviation Area deregulation.

Wizz Air Vienna (VIE) to Innsbruck (INN) within Austria

Hungarian-founded Wizz Air operates domestic intra-country routes across member states of the European Union.

Diplomatic & Legal Context:

The ultimate level of international aviation deregulation. Exists almost exclusively within the 27 EU member states and a handful of specialized bilateral agreements (such as Australia and New Zealand).

The Chicago Convention and Bilateral Agreements

On December 7, 1944, delegates from 54 nations gathered in Chicago to establish the legal framework for post-WWII civil aviation, creating ICAO.
The United States originally pushed for open global competition, but European nations, led by the United Kingdom, feared American airline monopolies and demanded strict bilateral traffic quotas.
The First and Second Freedoms were codified in the International Air Services Transit Agreement (IASTA), signed by over 130 nations.
The Third, Fourth, and Fifth Freedoms are typically exchanged in Bilateral Air Services Agreements (BASAs) negotiated country-to-country.
