Northern smog has affected aviation services in Mae Hong Son province, resulting in Kan Air cancelling its two morning flights between Chiang Mai and the province since March 19.
The airline has reduced it advance ticket-booking service to a daily basis during this period, Mae Hong Son Airport director Weerawat Thakhong said, adding that evening flights have not been affected.
The small dust particle level in Mae Hong Son’s Muang district was at 209 micrograms per cubic metre Saturday morning with visibility of less than 1,000 metres, dropping to 184mcg by early evening.
Anything above 120mcg is considered unsafe.
