According to officials from Seoul's Unification Ministry and ski governing body, the two Koreas are in discussions to transport some North Korean athletes via a flight which will fly between the North's Kalma Airport in Wonsan and the South's Yangyang Airport in Gangwon Province.

Yangyang Airport is about 70 kilometers north-east of Pyeongchang and 40 kilometers north of Gangneung, a sub-host city that will stage all ice sports events during next month's Olympics.

The two Koreas have already agreed to hold joint training for their skiers at the North's Masikryong Ski Resort, a roughly 45-minute drive from Kalma Airport, before the Olympics.

According to the Yonhap, the South plans to use Kalma Airport, a military airfield in the North's eastern port city of Wonsan, to transport South Korean non-Olympic skiers to the resort, a roughly 45-minute drive from the airport.

The two-day training is likely to take place as early as tomorrow.

For snow sports at the Pyeongchang Olympics, North Korea plans to send three Alpine skiers and three cross-country skiers.

"Three North Korean Alpine skiers are already training at Masikryong Ski Resort, and three cross-country skiers, who are currently in Samjiyon County, are set to move to the resort," an official with the Korea Ski Association said.

"If confirmed, a North Korean delegation of 30 members, including the six Olympic skiers, will probably take the chartered flight to Yangyang Airport."

North Korea previously said it will send 22 athletes and 24 coaches and administrative personnel as its national team for the Pyeongchang Olympics.

Fifteen women's ice hockey players came to the South last Thursday via a land route, and will play as part of an historic joint team.

If the air transport plan is confirmed, theoretically, all remaining North Korean national team members can come to South Korea.

North Korea previously said its delegation will use a western land route to come to the South.

The secretive state, under its leader Kim Jong-un, had become increasingly isolated from the world in recent months due to its insistence on pursuing a nuclear programme and its missile launches.

Strained rhetoric between Kim and United States President Donald Trump led to security fears surrounding the Games in Pyeongchang.

However, Kim's New Year's Day announcement that his country wanted to compete at the Games led to a thawing in relations.

This was tarnished somewhat yesterday when the North abruptly cancelled a cultural event involving both countries which was due to take place on its soil.
