the APC Building, on the grounds of Václav Havel Airport Prague in Ruzyně, 6th district, Prague. On 30 December 2009, ČSA announced it would sell its head office to the airport for CZK 607 million. Prior to the insolvency application, in February 2021, Czech Airlines moved their headquarters to the Smartwings building at Prague airport. Former subsidiaries Czech Airlines Handling provided ground handling or passenger and aircraft handling for many airlines operating flights from Prague. Czech Airlines Technics provided aircraft maintenance and regular certified servicing for the Czech Airlines fleet and other airlines. Czech Aviation Training Centre provided training to future aircrew members, as well as refresher and further training to existing crews operated by the state-owned enterprise Air Navigation Services of the Czech Republic. In addition to Czech Airlines, services of the training centre were also used by other airlines. Furthermore, "Flying without Fear" and "Stewardess/Steward Try-outs" courses were offered, as well as the "Flying for Fun" adventure course. These special trainings were also open to the public. Holidays Czech Airlines, a defunct charter subsidiary, focused mainly on flying to holiday destinations such as Greece, Turkey and Spain. The airline launched on 1 June 2010, and ceased in July 2014. Financial results Since its transformation to a joint-stock company in August 1992, ČSA has never paid dividends. The sale of a minority share to Air France was a fiasco, and the French airline withdrew. Subsequently, Antonín Jakubše and Miroslav Kůla stabilized the company and enlarged its fleet. In September 2003, Miroslav Kůla was fired. New CEO and ex-minister Jaroslav Tvrdík agreed with the unions to increase wages by a third and announced an "unprecedented" enlargement of the fleet. In 2005, the financial situation sharply deteriorated. Although the sale of two ATR aircraft improved operating results by CZK 198 million, the operating loss was almost half a billion Czech crowns and the Government of Jiří Paroubek replaced Jaroslav Tvrdík with Radomír Lašák. The airline generated further operating losses, despite revenues of CZK 2.1 bn from the sale of almost all real estate and CZK 1.2 bn from aircraft sales. In 2005–2010, ČSA generated an operating loss of CZK 3.4 bn; without long-term asset sale revenues, the operating loss would have been twice as large. The gross margin did not even cover personnel expenses. In 2016, the airline handled 2.7 million passengers and announced a net profit of 241 million crowns.
