kassasiipi

Kassasiipi is a Finnish slang term that translates roughly to "cash wing" or "money wing." It refers to a type of airplane, typically a commercial airliner, that is perceived as being particularly expensive to operate, maintain, or fly. The term is often used humorously or critically to describe aircraft that are seen as luxurious, fuel-inefficient, or simply costly.

The origin of the term is not precisely documented, but it likely arose from the visual of an aircraft with large wings, symbolizing a significant expenditure of resources. It can be applied to various aircraft models depending on the context and the speaker's opinion. For example, a private jet used by a wealthy individual might be referred to as a kassasiipi, as could a large, older passenger plane that is known for its high operating costs.

The term is primarily used in informal Finnish conversation, particularly online forums, social media, and casual discussions about aviation or transportation. It carries a connotation of extravagance or financial burden. While not a technical aviation term, it effectively communicates a specific sentiment about the perceived cost of certain aircraft.
