대한항공(Korean Air Lines) - Our smile

International flights to Hong Kong, Taiwan, and Los Angeles were flown with Boeing 707s until the introduction of Boeing 747 in 1973. In 1973, KAL introduced Boeing 747s on their Pacific routes and started a European service to Paris using the 707 and DC-10. In 1975 KAL became one of Airbus's first Asian customers with the purchase of three A300s, which were put into immediate service on Asian routes.
