Travel and Tourism are wide and multifaceted systems whose complexity is reflected in the terminology employed to describe them or to operate them. Their communication language appears at times secretive; but there is no secrecy, in fact. Travel activities are bound to a vehicle distinguished by its velocity. Operating such activities demands, therefore, a communication system able to match such rapidity. It is required that all performers are fluent in travel terminology, including students, airlines staff, travel agents, and other service providers. The Dictionary for Travel and Tourism Activities has been designed to solve the need to learn, understand and succeed with the most common terms and expressions used by these so-called "Industries". It is an educational tool for students and professionals, but is also an understanding means for travelers.
