Air connectivity across the Caribbean continues to operate within a legal framework largely built on bilateral agreements negotiated between states, a system whose foundations date back to the post-war development of international civil aviation.
The issue was among the themes discussed during the First Legal Seminar on Emerging Legal Frameworks in Civil Aviation organized by the Eastern Caribbean Civil Aviation Authority on 13–14 November 2025 in Antigua and Barbuda. Presentations delivered during the event examined the legal and regulatory mechanisms governing international air transport, including the continued role of Air Services Agreements in shaping regional aviation connectivity.
The post-war system still shaping international aviation
In a presentation titled “An Introduction to Air Services Agreements,” Ambassador Brian Challenger of Antigua and Barbuda’s Ministry of Civil Aviation outlined the origins of the bilateral aviation system still used today.
According to the presentation, the framework emerged following the adoption of the Chicago Convention of 1944, which established the technical and institutional foundations of international civil aviation. While the convention created a common regulatory framework for areas such as navigation and licensing, states did not reach agreement on a global multilateral exchange of traffic rights.
As a result, the allocation of commercial air traffic rights evolved primarily through bilateral negotiations between governments, creating the system of Air Services Agreements that continues to govern most international air routes today.
Why air services agreements still matter
Air Services Agreements define the legal conditions under which airlines may operate between countries. These agreements typically cover issues such as designated carriers, route rights, frequencies, capacity, pricing arrangements and operational provisions.
The agreements also establish conditions relating to ownership and effective control of airlines, while including provisions covering safety and aviation security obligations between states.
Negotiations for these agreements generally involve a wide range of stakeholders, including civil aviation authorities, foreign affairs ministries, airport operators, airlines and tourism agencies.
The presentation also noted that, in some situations where no formal air services agreement exists, states may rely on memorandums of understanding or technical arrangements to provide legal certainty for air services operations.
Liberalization efforts and regional models
The seminar also highlighted how approaches to aviation liberalization have evolved over time.
The 1946 Bermuda Agreement between the United States and the United Kingdom established one of the earliest templates for bilateral aviation agreements, based on tightly regulated allocations of commercial rights and capacity.
This framework evolved further with the Bermuda II Agreement of 1977, which introduced more liberalized approaches to route rights, capacity allocation and pricing. According to the presentation, subsequent developments contributed to the more liberal aviation agreements commonly used today.
Several multilateral models were also referenced during the seminar. These included the CARICOM Multilateral Air Services Agreement (MASA), designed to support regional aviation cooperation within the Caribbean Community, and the Multilateral Agreement on the Liberalization of International Air Transportation (MALIAT) involving the United States and Pacific Rim countries.
The presentation identified the European Union as the most advanced example of an integrated aviation market, combining commercial and technical regulation across member states.
Connectivity challenges in fragmented island markets
The continued importance of bilateral agreements reflects the broader complexity of aviation connectivity in island regions where multiple jurisdictions interact across relatively small markets.
At the ECCAA seminar, discussions on Caribbean connectivity highlighted the role played by aviation in supporting mobility, tourism and economic exchange across the region. Presentations also pointed to the importance of regulatory cooperation and institutional coordination in maintaining efficient regional air transport systems.
The legal framework governing international aviation therefore remains closely tied to diplomatic negotiations and intergovernmental cooperation, particularly in regions where air transport connectivity depends heavily on cross-border coordination.
Bilateral agreements remain central to regional aviation
Discussions during the ECCAA legal seminar illustrated how international aviation continues to operate within a legal architecture largely shaped by bilateral and multilateral agreements between states.
While liberalization efforts and regional cooperation initiatives have expanded in several parts of the world, Air Services Agreements remain a central mechanism governing market access, operational rights and regulatory oversight across Caribbean aviation markets.
