Thailand's aviation authority (CAAT) is systematizing development of six high-capacity regional airports (Surat Thani, Ubon Ratchathani, Khon Kaen, Nakhon Si Thammarat, Udon Thani, Krabi) serving 2,500–5,000 passengers/day. The strategy: tailored infrastructure expansion—not uniform growth—coupled with 50% fee cuts on landing/parking to incentivize new airline routes (6 months for new carriers, 12 months for new routes). Objective is to decentralize travel and economic activity from Bangkok, unlocking regional tourism, trade, and investment potential via interconnected transport and logistics hubs.
