Boutique Air is a US regional airline specializing in Essential Air Service (EAS) routes, providing scheduled passenger service to small and underserved communities across the United States. The carrier operates under contract with the US Department of Transportation, receiving federal subsidies to maintain air connectivity in regions that would otherwise lack commercial service. The airline primarily flies turboprop aircraft on short-haul routes, linking rural communities to larger hub airports. Boutique Air has held EAS contracts at numerous locations across states including Texas, Montana, North Dakota, Nebraska, and others. As a smaller regional operator, Boutique Air has faced operational scrutiny from the FAA and DOT at various points, including concerns over reliability and safety standards. Despite challenges, it continues to serve as a vital link for remote communities dependent on air service.
