If you’re booking a last minute flight to Chiang Mai or Chiang Rai for the Loy Kratong Yi Peng festival (Nov 28), please take note that around this time planes are not allowed in the skies after 6pm. At the time of going to print, only THAI had announced they will suspend all post-6pm flights from Nov 27-29, but normally other airlines do likewise. This is because the flying lanterns that are essential to the festival are not friendly to air travel, so the modern-day flying machines must make way.
