As an archipelagic state, Indonesia relies on air transportation for seamless connectivity. The two main actors in this mode of transportation are airlines and airports. The latter is usually less highlighted compared to the former. After the COVID-19 pandemic, Indonesia opened new opportunities in the air transportation industry through the enactment of Law No. 11/2020. Also known as the Indonesian Omnibus Law, it aims to simplify the investment process in various sectors, including air transportation. Currently, investors can establish an airline with only three aircraft—whereas the minimum requirement used to be ten. The Indonesian Omnibus Law aims to welcome new entrants to the airline business, which will hopefully encourage airport development. Still, the foreign direct investment nationality clause remains, which upholds single majority concept. In addition, airport development in Indonesia has faced a new chapter during the last decade, which is the introduction of the public–private partnership scheme. There were two state-owned enterprises airport operators, namely Angkasa Pura I and Angkasa Pura II, which were merged into InJourney Airports in September 2024, and they have been pushed to enter joint ventures with private investors with the aim of finding best practices on fair competition and innovation. This step is important as Indonesia is facing a more complex ASEAN Open Skies as the region is increasingly integrating in accordance with the ASEAN Economic Blueprint 2025. Finally, Indonesian airports are facing a domestic situation where the ceiling and floor prices are still implemented at domestic routes, leading to questions regarding flexibility.
