Jet Air Sp. z o.o. is a Polish air operator that provides leasing services as well as a branded operation on domestic and intra-European flights. The airline's branded operation is based in Bydgoszcz while it also flies under the LOT Polish Airlines name on several regional routes from Warsaw.
On 11 October 2007, LOT Polish Airlines announced it will cut the amount of routes Jet Air would fly, citing the lesser desirability of Jetstream aircraft as well as limited demand for these routes. In the end, this enabled Jet Air to begins its own operation as a stand-alone airline. Jet Air-branded flights began in late 2007 and the airline has since expanded the number of destinations it flies to.
