Boutique Air is a unique regional and commuter airline based in San Francisco, California. The airline is well known for its chartered flights across the United States. Boutique Air operates these flights with its fleet of Pilatus PC-12 aircraft. These single-engine turboprop aircraft are known for their ruggedness and ability to take off and land from smaller runways and airstrips. This ability makes it popular for utility operators in remote locations, but it also allows operators to fly the aircraft at smaller, less-flown airports.
