This normative research examines legal texts, mainly primary and secondary legal materials. This research found that, first, the changes in the Presidential Regulation regarding foreign investment in the field of public interest, such as airport services, were incompatible with the Constitution. The changes abolished the maximum percentage limit of foreign investment regulated in the previous provisions so that currently, foreign investment may carry out Government Cooperation with Business Entities on air transportation infrastructure projects without a percentage limit. Second, based on the Indonesian Constitution, ownership of air transportation should be under the state's authority, learning from China, which excessively applies foreign investors in the air transportation sector, causing consumer welfare to be affected by very high airplane ticket prices.</p></td></tr></tbody></table></div>
