On 5 July 2012, only two days after the carrier's employees went on strike amid mounting financial difficulties, the Uruguayan government decided to close the airline down and liquidate it. The carrier was wholly owned by the government at the time of its closure.


History


Foundation

The airline was established in September 1936 and started operations the following month, on 19 November 1936. It was set up by Jorge and Alberto Márquez Vaesa, two brothers who had obtained the necessary financial and technical support through the ambassador of the

Millington-Drake knew De Havilland's representative in Buenos Aires at the time, which helped in the acquisition of the airline's first aircraft. The airline flew two five-seater de Havilland Dragonflys from Montevideo to Salto and

In , the Canadian airline holding company Jazz Air Income Fund invested  million in LARAH. The move gave this holding an indirect control of 25% of the Uruguayan flag carrier, as LARAH had a participation of 75% into PLUNA at that time; the Government of Uruguay held the balance. In September and October 2010 three additional new CRJ900s aircraft were delivered from the Bombardier factory. In April 2011 three options were taken up for delivery at the end of 2011 and these were delivered between September and November 2011. With these additions, PLUNA's fleet consisted of 13 airplanes, the highest number in its history.

in the preceding months. Later on, with losses totalling  million, Leadgate disposed of their 75% stake in the airline, transferring it back to the Uruguayan government. By that time, that percentage of PLUNA's stock was owned by LARAH, which was in turn 75% owned by Leadgate and 25% by Jazz Air. Despite being initially disclosed that Jazz Air was not interested in taking over the entire 75% stock, and that it was later informed that the Canadian airline was evaluating the acquisition, the government suspended PLUNA's operations on —following a strike that started two days earlier, after failing to find new investors for the company. The government announced that both PLUNA's fleet and routes would be auctioned. It seemed there were no plans for the government to have any stake in PLUNA's successor. In , the auction of the seven Bombardier aircraft that belonged to the liquidated carrier was delayed until as there were no bidders. Cosmo Airlines, a Spanish charter carrier, eventually purchased the seven aircraft at a price of $137 million. Regionally, the void created by PLUNA's collapse benefited foreign airlines on some routes. In 2016, a Uruguayan court concluded that no Leadgate executives were responsible for Pluna's collapse. Two years later, in 2018 a Panamanian-based investment consortium named Caballero Verde S. de R.L. took ownership of LARAH, which still owned 75% of Pluna's shares. The consortium plans to seek compensation from the Uruguayan government for Pluna's demise.
