OLT Express Poland (ICOA: YAP) was a Polish charter airline, formally known as Yes Airways. On 31 July 2012 it suspended all charter services, less than a week after the scheduled sister airline OLT Express Regional cancelled all its services. Stranded customers were returned home on LOT services. All leased aircraft were repossessed by lessors, and even some wet lease pilots were released back to their employer airlines. Its sister airline, OLT Express Regional (ICOA: JEA), filed for bankruptcy on 27 July 2012 after its licence was suspended by the Polish Aviation Authority. Yes Airways was founded in 2009 and was based in Warsaw. It began operations in late April 2011. It flew from regional airports in Poland on behalf of tour operators and was the first Polish airline to have Airbus aircraft in its fleet. In early 2012, YES Airlines was rebranded as OLT Express Poland by its new owners, Amber Gold, who also controlled OLT Express Germany and OLT Express Regional. The airline's main hub was located at Warsaw Chopin Airport. On 31 July 2012 OLT Express Poland followed its sister airline OLT Express Regional in suspending all services. All leased aircraft were returned to their owners. The third sister company, OLT Express Germany, announced they are seeking an external investor to support operations, and fund the earlier announced takeover of Contact Air. OLT Express Regional - Scheduled services OLT Express Regional began life in 2001 as Jet Air, an airline operating in the business aviation sector, providing broker rendering services (small aircraft and helicopters) to local operators and companies. Jet Air started scheduled domestic operation for LOT Polish Airlines in winter 2005/06 with three BAe Jetstream 32, flying on routes with less demand (like Zielona Góra, Bydgoszcz, and Rzeszów). On 11 October 2007, LOT Polish Airlines announced it would cut the amount of routes Jet Air would fly, citing the lesser desirability of Jetstream aircraft as well as limited demand for the destinations served by Jet Air. In the end, this enabled Jet Air to begin its own operation as a stand-alone airline. Jet Air-branded flights began in late 2007 and since then the airline rapidly expanded the number of destinations it flew to. Starting from October 2010, Jet Air operated flights on behalf of Ostfriesische Lufttransport (OLT) from their hub at Bremen Airport to both Nuremberg Airport and Brussels Airport. These flights ceased in May 2011.
