Chiang Mai International Airport has cancelled 108 flights and rescheduled another 80 ahead of the Yi Peng and Loy Krathong festivals, which take place from November 21 to 28, 2026. The cancellations are due to safety risks posed by the release of thousands of paper lanterns near flight paths.
Air traffic restrictions will be in place on November 24 and 25, limiting operations to 12 hours daily. Airlines are adding 105 special flights outside the peak lantern-release windows to manage passenger demand.
Airport authorities are working with local agencies to ensure safety during the festival period.
The Yi Peng and Loy Krathong festivals are major cultural events in northern Thailand, drawing large numbers of visitors. The lanterns, known as khom loi, are released as part of the Yi Peng festival, while Loy Krathong involves floating decorated baskets on water.
Authorities have prohibited lantern releases in designated red zones near flight corridors to prevent safety hazards. Ground crews will conduct regular inspections to remove fallen lanterns and debris from runways and airport grounds.
Passengers travelling between November 21 and 28 are advised to check flight status directly with their airlines and use online check-in facilities during the festival period. They should also allow additional time at the airport, arriving at least two hours before domestic departures and three hours before international flights.
