LEAV Aviation

LEAV Aviation (IATA: KK) is a German airline with its registered office in Cologne. Its public network is leisure-oriented: LEAV’s own site lists German points such as Cologne, Frankfurt and Munich alongside holiday destinations including Mallorca, Greek islands and Lapland. The carrier is not best understood as a classic full-service network airline; its own materials describe a mix of scheduled leisure flights, charter flying and ACMI/wet-lease work for airlines and tour operators. I found no official basis showing that LEAV runs its own frequent-flyer program or belongs to oneworld, Star Alliance or SkyTeam, so travelers focused on mileage credit should check the ticketing carrier or tour-operator documentation before booking.
