Korean Air Lines expects to reopen code-sharing pacts with Delta Air and Air France in time for the World Cup finals. Korean Air's ties with the two were severed for about three years after the airline was involved in a series of crashes. Officials of Delta and Air France will come to Korea to sign the agreements in February. A Korean Air official said the code-sharing agreements will take effect again from April or May. South Korea and Japan will co-host the World Cup, which kicks off on May 31st.
