RTC is relaunching its Chiang Mai public bus service, starting with Route 24 linking the airport, Nimman, Chang Phueak, Warorot market, Tha Phae Gate and Wua Lai Road. Free rides run 10–19 October with 2 buses, rising to 3 buses on 25 October, 5 with EVs in late November, and 7 full EV-era buses in December, running 06.00–22.00. The flat fare stays at 50 baht, every 20 minutes per bus, with cashless tap-to-pay by Mastercard and QR tickets. Monthly passes are planned. Ridership target is 500–700 a day, up from under 200. Small businesses near the route, especially around Warorot and Tha Phae, may see more day visitors and workers; cashless payment is the main thing to check if you take card or QR.
