KlasJet

KlasJet (ICAO: KLJ) is a Lithuanian charter airline specializing in private and corporate jet services, along with ACMI (Aircraft, Crew, Maintenance, and Insurance) leasing. As a subsidiary of Avia Solutions Group, KlasJet has established itself as a provider of bespoke aviation solutions across Europe, the Middle East, Africa, and Asia.

KlasJet was founded in October 2013 by Avia Solutions Group, receiving its Air Operator Certificate (AOC) and commencing commercial flights in 2014. The airline's headquarters are located in Vilnius, Lithuania, at Vilnius International Airport (VNO). Beyond its primary base, KlasJet maintains operational presence and strategically bases aircraft in various locations across Western and Eastern Europe, Africa, and the Middle East, including recent expansions to cities like Belgrade, Dhaka, Munich, Prague, Bratislava, Porto, Kinshasa, Cologne, Berlin, and Milan Malpensa, to cater to diverse client needs.

The KlasJet fleet primarily consists of Boeing 737 aircraft variants, including modified 737-300, 737-500, and 737-800 models. As of November 2025, the fleet includes 8 Boeing 737 aircraft variants, with plans to expand to 10 VIP configuration aircraft and add a Boeing 737 BBJ2. Historically, KlasJet also operated Bombardier Challenger 850 and Hawker 800XP aircraft. KlasJet specializes in VIP charter flights and ACMI services, offering a route network that is client-driven rather than fixed. This allows for global reach, operating flights tailored to individual, group, and corporate travel requirements across continents.

KlasJet is not a member of major airline alliances like Star Alliance, SkyTeam, or Oneworld. However, it is an integral part of the Avia Solutions Group, which is recognized as the world's largest ACMI provider. The airline offers notable services such as bespoke corporate charters, featuring customized interiors, VIP terminal access, fine dining, and the capability to handle non-standard cargo, including animals. For VIP flights, aircraft are configured with luxury business-class seating for 10 to 68 passengers. Additionally, for its ACMI operations, KlasJet provides high-density layouts (186 to 189 passengers) and is reconfiguring some Boeing 737-800s to offer a twin-class configuration with 12 business class seats and 162 economy seats.
