Two new charter Web sites have hit the market. Halogen Guides last month launched Halogen Guides Aircraft Marketplace, an online marketplace for business jets that allows users to search for jets by make, model, year, price, air time and the aircraft’s location. Meanwhile, Concord, Mass.-based air-taxi firm Linear Air unveiled a Web-based system that allows travelers to check pricing and book flights online.
