Overview
Czech Airlines, known in Czech as České aerolinie and commonly abbreviated ČSA or CSA, is a Czech aviation brand and holding company based in Prague. Established by the Czechoslovak government on 6 October 1923, it began operating scheduled services later that month and became the national airline of Czechoslovakia, followed by the Czech Republic after the federation's dissolution. The brand's long history includes domestic aviation, European scheduled services, intercontinental routes, Soviet-built aircraft during the socialist period, and later fleets made up primarily of Western aircraft. The airline's first transport flight connected Prague and Bratislava. It opened its first international route to Zagreb in 1930, but its original corporate existence ended after the dismemberment of Czechoslovakia in 1939. Operations resumed after the Second World War, with scheduled services restarting in 1946. During the Communist period, political and trade restrictions pushed the airline toward Soviet-designed aircraft. ČSA became an early jet operator when it introduced the Tupolev Tu-104A in 1957; its Prague–Moscow service was described as the first regular jet-only route, at a time when other carriers generally combined jet and piston or turboprop aircraft. It later operated Bristol Britannia, Ilyushin Il-18, Tupolev Tu-134 and Tu-154, and Ilyushin Il-62 aircraft. Transatlantic flying reached destinations including Havana, Montreal and New York. The company was reorganized around the political changes of the early 1990s. In 1991, Czechoslovak Airlines split from Slov-Air, and after the breakup of the federation it adopted the Czech Airlines name in 1995. Privatization and ownership changes followed, with Air France, Czech state entities and other institutions among the shareholders during the 1990s and 2000s. The fleet progressively moved away from Soviet types toward Boeing 737 and Airbus aircraft. ČSA joined the SkyTeam alliance in 2001 and maintained the OK Plus frequent-flyer programme, whose name reflected the airline's IATA code and aircraft-registration identity. Financial weakness led to repeated restructuring and changes in control. Korean Air acquired a 44% stake in 2013, while Travel Service, later associated with Smartwings, became the dominant shareholder from 2015 onward. The airline briefly returned to profitability in 2016, but route reductions, fleet downsizing and competition within the Smartwings Group weakened its independent position. The COVID-19 crisis sharply reduced its workforce, fleet and network. ČSA sought a moratorium in 2020 and filed for bankruptcy in March 2021. It subsequently completed a court-supervised restructuring in 2022 under an ownership structure involving Prague City Air and Smartwings. By 2023, Prague–Paris was the only remaining route operated under the Czech Airlines name. In October 2024, the company was transformed from an independent operating airline into a holding-company structure, while Smartwings assumed flight operations under both brands. The final scheduled Czech Airlines flight, OK767 from Paris Charles de Gaulle to Prague, arrived on 26 October 2024. The Czech Airlines brand remains active within the group, including through aircraft carrying its livery, but it no longer operates an independent scheduled network. In December 2025, Pegasus Airlines was reported to have signed an agreement to acquire the holding company for €154 million; the completion status of that proposed transaction is not established by the supplied material.
History
Czech Airlines was created on 6 October 1923 by the Czechoslovak government as Czechoslovak State Airlines. Its first transport service followed twenty-three days later between Prague and Bratislava. The carrier initially concentrated on domestic flying and added its first international route, from Prague through Bratislava to Zagreb, in 1930. The breakup of Czechoslovakia in 1939 brought the original airline to an end. Following the Second World War, the company was re-established as Czechoslovak Airlines. Irregular services resumed in September 1945 and scheduled operations restarted in March 1946. After the Communist takeover in 1948, several Western European and Middle Eastern routes were suspended or reduced, while the fleet shifted toward Soviet aircraft because Western equipment and spare parts were difficult to obtain. Czechoslovak-built versions of the Ilyushin Il-14 formed part of this period's fleet. In 1950, three ČSA Douglas DC-3 aircraft were hijacked and diverted to Erding in West Germany. The event became a major Cold War propaganda episode; many passengers were unwilling participants and later returned to Czechoslovakia, while others sought asylum. The incident remains one of the most notable episodes in the airline's history. ČSA entered the jet age in 1957 with the Tupolev Tu-104A. Its Prague–Moscow service was the first regular jet-only connection, and ČSA was the only operator besides Aeroflot to use that aircraft type. The airline began transatlantic operations in 1962 with a Bristol Britannia leased from Cubana de Aviación, later serving Havana, Montreal and New York with intermediate refuelling stops. During the following decades it operated substantial fleets of Soviet-designed aircraft, including the Tu-134, Tu-154, Il-18 and Il-62. The Il-62 became its principal long-range jet and was also used for official government transport. The early 1990s brought corporate and political restructuring. Czechoslovak Airlines separated from Slov-Air in 1991, while privatization followed in 1992. After the federation was dissolved, the company adopted the Czech Airlines name in March 1995. Through the late 1990s, Soviet aircraft were progressively replaced by Boeing and Airbus types. ČSA became a full SkyTeam member in October 2000 and continued to operate from Prague's principal airport, now Václav Havel Airport Prague. The carrier experienced continuing financial pressure in the 2000s and 2010s. Ground personnel were transferred to a separate handling subsidiary in 2010, and the European Commission investigated whether state assistance could support a viable restructuring. Korean Air purchased 44% of the company in 2013, and Travel Service acquired a major holding in 2015. Travel Service later bought Korean Air's stake and the Czech state's interest, bringing the airline under effective Smartwings Group control. There was a short period of improvement in 2016, when passenger volumes and load factor increased and the airline reported a return to profit. However, route withdrawals and fleet reductions resumed. Plans for Airbus A320neo aircraft were reduced and later converted into Airbus A321XLR orders, but those plans were cancelled after the COVID-19 pandemic. The pandemic also ended the Seoul long-haul service and led to the return of the leased Airbus A330. ČSA entered a moratorium in 2020 and filed for bankruptcy in March 2021. Its workforce and active fleet contracted sharply, and maintenance creditors sought seizure of ATR aircraft over unpaid bills. By 2022 the company had completed restructuring, but its scheduled network was greatly diminished. Prague City Air became the majority owner in a new arrangement in which Smartwings retained a minority stake. By 2023, Prague–Paris was the only scheduled route operated under the Czech Airlines brand. In October 2024, the operating airline was converted into a holding-company structure, with Smartwings taking over flight operations under both the Smartwings and Czech Airlines brands. The final Czech Airlines scheduled service was OK767 from Paris to Prague on 26 October 2024. The brand continues within the group, but its independent airline operations have ceased. A proposed acquisition of the holding by Pegasus Airlines was announced in December 2025; the supplied references do not establish whether the transaction was completed.
