Jin Air will be operating seven Seoul Incheon-Clark charter flights from 14 January to early February and sometime in February it hopes to turn it into a scheduled service, says a Jin Air spokesman.
He was unable to say what the frequency will be because this development is in the early stages of planning, he adds.
Jin Air has a fleet of four Boeing 737-800s and in March plans to get a fifth 737-800, he says.
It has capacity to launch services to Clark because it recently stopped operating charter flights from Seoul Incheon to Tokyo Haneda.
The spokesman attributed the suspension of Tokyo Haneda services to the passenger loads and too few landing slots at Haneda airport.
Clark is an airport on the outskirts of Manila and Koreans are the largest group of foreign tourists to the Philippines. Bangkok is Jin Air's other international destination for scheduled services.
