Travel technology (also called tourism technology, and hospitality automation) is the application of Information Technology (IT) or Information and Communications Technology (ICT) in the travel, tourism and hospitality industry. One form of travel technology is flight tracking.

Since travel implies locomotion, travel technology was originally associated with the computer reservations system (CRS) of the airlines industry, but now is used more inclusively, incorporating the broader tourism sector as well as its subset the hospitality industry. While travel technology includes the computer reservations system, it also represents a much broader range of applications, in fact increasingly so. Travel technology includes virtual tourism in the form of virtual tour technologies. Travel technology may also be referred to as e-travel / etravel or e-tourism / etourism (eTourism), in reference to "electronic travel" or "electronic tourism".

eTourism can be defined as the analysis, design, implementation and application of IT and e-commerce solutions in the travel&tourism industry; as well as the analysis of the respective economic processes and market structures and customer relationship management.

From a communication science perspective, eTourism can be also defined as every application of Information and Communication Technologies (ICTs) within both the hospitality and tourism industry, as well as within the tourism experience.

Travel technology is increasingly being used to describe systems for managing and monitoring travel, including travel tracking and flight tracking systems.

In other contexts, the term "travel technology" can refer to technology intended for use by travelers, such as light-weight laptop computers with universal power supplies or satellite Internet connections. That is not the sense in which it is used here.
