Premises of aero-nationalism
The principles of international air law, together with the Chicago Convention, allow for the establishment of a system of air services agreements. The system of the Chicago Convention and the air services agreements include a number of exceptions to the airline nationality concept, the most prominent of which are the 'blind-eye' policy and the presence of multinational carriers. As air services agreements are binding upon governments, such national laws may generally provide for authorization of those carriers that are duly designated under the agreements. The application of authorization conditions in air services agreements is left to the states' discretion, which can lead to other types of interactions. Traditionally, the criteria for authorization in air services agreements are identical for the contracting parties. Yet, when certain commercialized authorization conditions are introduced into air services agreements, instances of asymmetric authorization criteria can arise.
