# One of Thailand’s main airlines, Bangkok Airways, is suspending flights between Bangkok and Mae Hong Son because of poor visibility caused by air pollution. Air pollution spikes between December and April in Thailand as farmers burn stubble to prepare land for the next crop season. The smog was expected to make visibility too poor to land. The airport authority in Mae Hong Son, a popular stop on the backpacker trail in northern Thailand, announced that flights would be suspended from 15 March to 20 April.
