Air Koryo operated charters from Sondok Airport to Yangyang Airport during 2002–2006 for few months per year. Flights were halted indefinitely after relations soured between the two Koreas.
Yangyang International Airport handled its last flight on 1 November 2008, according to the Korea Airport Corporation, and there were calls for it to be sold off or closed.[2] It reopened on 16 July 2010 when East Asia AirLine started flying to Busan.
On 4 August 2011, Taiwan's TransAsia Airways began flying to Yangyang International Airport (five times a week). TransAsia Airways stated that it will be a regular chartered service. However, on 18 February 2017, TransAsia Airways went into liquidation.[3]
This includes a visa-free grace for the Philippines, Indonesia, and Vietnam so long as citizens land in Yangyang. VietJet Air is the only airline carrier that operates flights from South East Asia to Yangyang (charter flights from Hanoi to Yangyang).[6]
