At least 78 flights at Chiang Mai airport will be cancelled this Friday and Saturday to avoid hazards posed by floating sky lanterns during the traditional Yi Peng festival.
Airlines will cancel 58 domestic and 20 international flights over the two days.
Domestic airlines will also reschedule 53 flights and international carriers 26 flights, during the same period.
