Cape Air is a regional American airline headquartered in Hyannis, Massachusetts, founded in 1989. The carrier specializes in essential air service to smaller, underserved communities, particularly in New England, the Caribbean, and the Great Plains, operating thousands of flights per week across its network. The airline is best known for its extensive use of small piston and turboprop aircraft, making it one of the largest operators of Cessna 402s in the world. Cape Air holds codeshare agreements with major carriers including United Airlines and American Airlines, allowing passengers to book seamless connections. Cape Air plays a critical role in the Essential Air Service (EAS) program, receiving federal subsidies to maintain scheduled service to remote communities that would otherwise lack commercial air access. The airline has built a reputation for reliability and community commitment in the markets it serves.
