Development since the 2000s
In May 2005, the airline was withdrawn from the Luftfahrt-Bundesamt, as serious defects on the airline's aircraft had been discovered. As a counter-reaction, Turkey then withdrew the German airlines' landing permits. After protests by the Foreign Office, the entry ban for German aircraft was lifted again. On 14 May, the airline's entry permit was withdrawn by the Swiss and French aviation safety authorities. Until then, Onur Air had been awarded a total of nine certificates by Airbus and Boeing for their maintenance procedures. In the period from July 4 to 6, 2005, the review of the airline was provisionally concluded with a so-called "final meeting" at the home airport of Onur Air in Antalya, in accordance with the requirements from the re-issue of the entry permit.
By 6 April 2019, all of Onur Air's flights from their former base at Atatürk Airport were relocated to the new Istanbul Airport.<ref[6]
In August 2019, Onur Air established a new, partly owned subsidiary named Holiday Europe for leisure flights between Europe and destinations around the Mediterranean. Onur Air provided aircraft and crews for the new brand.<ref[7] In October 2021, the operational license of Holiday Europe has been revoked.<ref[8]
In December 2021, the Turkish aviation authorities did not renew the airline's operational license, suspending all of their operations. Beforehand, negotiations to regain financial stability in the wake of the COVID-19 pandemic failed.<ref[9]
In February 2022, Onur Air's last remaining airworthy aircraft was taken back by its lessor, leaving the airline without a usable fleet.<ref[10] In April 2022, a Turkish court declared the airline bankrupt after legal proceedings of a former employee.<ref[11]
