Air Algerie said in a statement that a man threatened the crew, demanding the plane be refuelled and flown to South Korea. The airline said he wanted to see "a high official" on landing.
On arrival at Algiers' Houari Boumediene airport, "the flight captain with the help of security forces managed to overpower the individual," the statement said. He was arrested and was being held by security forces.
The hijacker "was not behaving normally and was apparently under the influence of drugs," Air Algerie added.
Earlier reports that he had two accomplices carrying bombs were unfounded, security sources said.
