AirDialog (doing business as Linear Air) is the lighter, smaller, and less crowded cousin of commercial airlines. Linear Air provides air-taxi services to passengers using a fleet of small private jets. Serving mostly groups of business travelers and some leisure travelers, the company flies in and out of regional airports located in more than 750 northeastern US and eastern Canadian cities. The company has operations in Boston and New York as well. Linear Air was founded in 2004 by current CEO William "Bill" Herp. Linear Air's fleet is comprised of nearly 10 Cessnas and Eclipse jets, but the company looks to expand its fleet in the future.
