The application uses information from the Quantitative Air Services Agreement Review (QUASAR), which documents developments in the air transport sector. QUASAR was devised by the WTO Secretariat.

The Air Services Agreement Projector allows the user to select bilateral air services agreements on the basis of a number of criteria, namely by signatories and regions, levels of openness, and traffic levels. Once selected, these agreements are charted on a map and the relevant underlying data is displayed.
