Bilateral air service agreements: US-EU open skies treaty

Bilateral air service agreements form the foundation of international air traffic rights. These agreements determine which airlines can operate between two countries, the routes they can fly, and the frequency of services. The US-EU Open Skies Treaty, implemented in 2008, stands as a landmark agreement that liberalized air travel between the United States and European Union member states.

This agreement has had profound implications for air cargo operations, enabling greater flexibility in route planning and capacity allocation. However, it also intensified competition, forcing carriers to adapt their strategies and seek new efficiencies to remain competitive in the transatlantic market.

Iata's dangerous goods regulations impact on cargo flow

The International Air Transport Association (IATA) Dangerous Goods Regulations play a crucial role in ensuring the safe transport of hazardous materials by air. These regulations define how dangerous goods must be classified, packed, marked, labeled, and documented for air transport.

While essential for safety, these regulations can significantly impact cargo flow and handling processes. Carriers must invest in specialized training, equipment, and facilities to comply with IATA standards. Additionally, the restrictions on certain types of dangerous goods can affect routing options and transit times, particularly for industries like pharmaceuticals and electronics manufacturing.

Cabotage restrictions: domestic market protection measures

Cabotage restrictions, which limit or prohibit foreign carriers from operating domestic routes within a country, represent another significant regulatory constraint in air logistics. These protectionist measures are designed to safeguard domestic airlines but can lead to inefficiencies in global supply chains.

For example, a foreign carrier transporting goods from New York to Los Angeles via Tokyo would be prohibited from carrying cargo between the two U.S. cities, even if capacity is available. This limitation can result in underutilized aircraft capacity and increased costs for shippers.
