For the pricing of regular aviation in Joinville, Palmas, Petrolina, Imperatriz, Bagé, Uruguaiana, and Pelotas, the concept of tariff freedom is used and the tariffs are adjusted by the concessionaire based on good pricing practices and by checking with the involved parties.

The tariff freedom concept is also applied for general and executive airport tariffs, and for storage and handling tariffs (except for transit cargo) of all the airports mentioned here and also for the airports of Bacacheri and Pampulha.
