The number of air passengers in Turkey this January-May-including transit passengers-totaled 33.7 million, according to the country's airport authority.
The five-month figure slipped 54.7% from the same period last year, the General Directorate of State Airports Authority (DHMI) said on Monday.
The drop stemmed from global coronavirus-related travel restrictions.
Domestic passenger numbers shrank 51.7% to 19.5 million, while 14.2 million passengers took international flights, down 58%, during the same period.
Turkish airports served 408,483 planes including overflights in the first five months of this year, down from 755,171 in January-May 2019.
The report also said cargo traffic stood at 922,610 tons in the first five months of 2020.
