Thailand has introduced a campaign offering free domestic flights to international travelers booking directly with six participating airlines. Running from September to November 2025, the program connects major cities like Bangkok with secondary destinations such as Ayutthaya, Sukhothai, and Krabi. Aimed at easing overcrowding in hotspots like Phuket, it helps spread tourism benefits, support local economies, and promote eco-friendly travel. Authorities expect substantial revenue gains alongside cultural and environmental preservation.
