Croatia Airlines Ltd. is the state-owned flag carrier of Croatia. It is headquartered in Buzin near Zagreb and operates domestic and international services mainly to European destinations. Its main hub is Franjo Tuđman Airport with focus cities being Dubrovnik, Split, and Zadar. Since November 2004, the airline has been a member of Star Alliance.

The airline was established on 20 July 1989, trading with the name Zagal (formally, Zagreb Airlines), and started operations using a single Cessna 402 aircraft on cargo services for UPS. After the first democratic elections held in Croatia, Zagal changed its name to Croatia Airlines on 23 July 1990.

In 1991 Croatia Airlines signed an agreement with Adria Airways which allowed it to lease a McDonnell Douglas MD-82 to commence domestic jet services between Zagreb and Split. Due to the Croatian War of Independence and the closure of the airspace over Croatia, the airline was soon forced to suspend operations. As soon as flights restarted, Croatia Airlines acquired three Boeing 737s from Lufthansa and became a member of the International Air Transport Association (IATA). As the flag carrier of newly-independent Croatia, the airline launched its first international service on April 5, 1992, from Zagreb to Frankfurt.

In 1993, two new ATR 42s and two more 737s joined the fleet and representative offices were opened in several European cities and the company bought the travel agency Obzor to organize travel packages for groups and individuals. By 1994, Croatia Airlines had welcomed its one millionth passenger. Later that year, Pope John Paul II flew the airline on a trip to Croatia.
