International Air Law
The Paris Convention was the first international treaty to address the legal regime of airspace. It recognized the principle of complete and exclusive sovereignty of states over the airspace above their territory, including land territory and territorial waters. At the same time, it acknowledged freedom of navigation over the high seas and recognized, subject to certain limitations, the right of innocent passage for civil aircraft of contracting states.
The Convention also restricted member states from concluding air transport agreements with non-member states.
Settlement of International Disputes in Air Law
Following revisions to the Paris Convention, the 1929 amending protocol allowed third states to accede and removed certain privileges previously granted to major powers. It also recognized the right of member states to conclude agreements with non-member states.
After the adoption of the Chicago Convention in 1944, earlier air law treaties, including the Paris and Havana Conventions, were effectively superseded.
The Chicago Convention entered into force in 1947 and has since been widely accepted by the international community.
The principal features of the Chicago Convention include the following:
- Recognition of the complete and exclusive sovereignty of each state over the airspace above its territory, including land territory, territorial sea, and protected areas.
- Recognition of freedom of flight over the high seas.
- Prohibition of state aircraft of member states from flying over or landing in the territory of another state without special agreement or authorization.
- Prohibition of the use of weapons against civil aircraft in flight.
- Freedom of flight and landing for non-state aircraft of member states, except for aircraft engaged in scheduled international air services, which require special authorization.
- Exclusive right of each state over domestic air transport services within its territory, which is non-transferable.
- Authority of member states to impose necessary and non-discriminatory restrictions or prohibitions.
- Recognition of the right to inspect aircraft and related documents.
- Discretion of member states in times of war.
- Establishment of the International Civil Aviation Organization.
Recognized Freedoms in International Air Law
The international community has generally accepted the following freedoms:
- The freedom to fly over the territory of member states without landing.
- The freedom to land for non-commercial purposes.
- The right to unload cargo, mail, and disembark passengers.
- The right to load cargo, mail, and embark passengers.
The Hague Convention of 1970
The Hague Convention of 1970 was the first international instrument specifically adopted to suppress the unlawful seizure of aircraft. Under this Convention, the state of registration of the hijacked aircraft has jurisdiction to prosecute the offense.
Where the aircraft is registered jointly or internationally, the interested states shall designate a competent state to exercise jurisdiction.
Frequently Asked Questions Regarding International Air Law
The legal regime of airspace consists of international rules and principles governing state sovereignty over airspace and the freedom of navigation by aircraft. It is primarily derived from treaties such as the Paris Convention and the Chicago Convention.
Under the Paris and Chicago Conventions, every state has complete and exclusive sovereignty over the airspace above its land territory and territorial waters, and may regulate its use subject to international law.
Freedom of flight over the high seas allows civil aircraft of member states to navigate the airspace above international waters without interference, subject to applicable international regulations.
Non state aircraft of member states may fly over and land in the territory of other member states, except for aircraft engaged in scheduled air services, which require special authorization.
The Hague Convention of 1970 addresses the suppression of unlawful seizure of aircraft. It grants jurisdiction to the state of registration of the hijacked aircraft, or to a designated state in cases of joint or international registration.

If an international flight is delayed for many hours, can passengers claim compensation from the airline?
Passenger rights for flight delays depend on factors such as the airline’s location, the route, applicable regulations, and the reason for the delay. Different legal systems provide different protections, so the specific circumstances should be reviewed before determining what remedies may be available. International air law often involves multiple jurisdictions and regulatory frameworks.
If my luggage is lost during an international flight, should I sue the airline or the airport?
Responsibility for lost baggage depends on the circumstances of the loss, the airline’s obligations, and the applicable international and domestic rules. In many cases, the airline may be the relevant party to contact, but the available legal options depend on the details of the situation.
Are airlines responsible if a passenger gets injured during an international flight?
Airline liability for passenger injuries can depend on factors such as where the injury occurred, the cause of the incident, and the applicable legal framework. International aviation law includes rules regarding carrier liability, but each case requires reviewing the specific facts.
If an airline cancels my flight without a good reason, what legal rights do I have?
The rights of passengers after a cancellation depend on the airline’s obligations under the applicable laws, the terms of carriage, and the circumstances behind the cancellation. Some situations may create rights to assistance or compensation, while others may not.
Can an Iranian company make a contract with a foreign airline under international air law?
Yes, international aviation transactions often involve parties from different countries and may require consideration of contract law, aviation regulations, and international agreements. The terms of the contract and the laws chosen by the parties can be important factors.
If cargo is damaged during an international flight, who is responsible for paying the loss?
Responsibility for air cargo damage depends on several factors, including the transportation agreement, the condition of the cargo, the cause of damage, and applicable liability rules. The documents related to the shipment are usually important when evaluating a claim.
Does international air law apply only to airlines, or does it also affect passengers and companies?
International air law covers a wide range of issues involving airlines, passengers, cargo operators, airports, and other participants in aviation activities. Its application depends on the type of legal issue and the relevant regulations.
Can an airline refuse to carry a passenger because of a legal issue?
Airlines may have certain rights and obligations regarding passenger acceptance, but these decisions can depend on safety requirements, immigration rules, airline policies, and applicable laws. The legality of a refusal depends on the facts of each situation.
If two airlines from different countries have a dispute, which court handles the case?
Cross-border aviation disputes can involve questions about jurisdiction, applicable law, arbitration agreements, and international conventions. The answer depends on the contracts between the parties and the countries involved.
Why does international air law need separate rules? Can’t normal commercial law handle airline disputes?
Aviation involves international travel, safety requirements, and transactions that cross multiple borders. Because of these unique characteristics, international air law developed specific rules addressing matters such as aircraft operations, liability, and cooperation between countries.
