TPP governs cross-border trade in aviation services under the guidance of trade liberalization idea. On the basis of GATS and its Annex on Air Transport Services, TPP governs six types of trade in aviation services and draws support from“negative exception”and other forms. The effect of TPP trade in cross-border aviation services rules is behind Air Transport Agreement, and Annex on Air Transport Services. TPP contracting parties take strict reservations on cross-border trade in aviation services in its Annex I and II. A new liberalization order on international trade in aviation services has not been built in TPP. TPP exerts very limited influence on international trade in aviation services and can not assault non-contracting parties. Bilateral Air Transport Agreement and free trade agreements are the critic platforms for all parties including TPP contracting parties to govern international trade in aviation services.
