Travel agencies have gradually been disintermediated since the late 1990s as airlines and other travel companies began selling directly to customers online. In response, travel agencies developed internet presences and websites to allow online booking. While some travel can now be booked directly online, travel agents remain important for arranging complex trips, offering advice, and fully bonded packages. The market for travel agencies has declined since the rise of online booking, but some agencies have adapted by specializing in specific areas of travel or acting as travel consultants.
