South Korean international air traffic increased by 22.6% in April 2012, with just under 3.8 million passengers.
According to South Korea's ministry of land, transport and maritime affairs, China's Labour Day holidays, the Golden Week in Japan and South Koreans travelling abroad to locations such as Southeast Asia were all responsible for the rise in air travel.
The report revealed that passenger traffic on Japanese routes rose 52.2% over the same period in 2011, while traffic to Oceania, Southeast Asia and China also increased 24.1%, 21.6% and 3.2% respectively.
The country's domestic passenger traffic grew 5.5% to 2 million passengers during April, when compared to the same month in 2011.
However, South Korea's total air cargo volume declined by 3.1% to 284,000t, led by a 3.4% decline in international cargo volume to 260,000t, though the domestic cargo traffic volume rose 0.9% to 24,000t during the month.
According to the ministry, the cargo volume was affected by slow economic conditions in the European Union and concerns on foreign exchange rates and global oil prices.
International and domestic flight movements in the country have increased by 9.2% to 45,228, when compared with the corresponding period in 2011.
The country's full service carriers were responsible for 67.2% of total international passenger traffic in April, while the low cost carriers (LCC) accounted for 7.1% of the total international passenger numbers.
LCCs carried 860,000 passengers on domestic routes during the period, reporting an 11.3% rise.
