This chapter aims to detect the differentiating factors of the accessible e-travel agencies that enable them to be competitive in the market and, therefore, to promote the development of accessible products in the tourism sector. With this objective, an analysis of 14 accessible travel agencies' websites has been carried out. The analysis was guided by theoretical frameworks of competitiveness and accessible tourism. Taking into account the specific needs of people with disabilities, accessible e-travel agencies offer a wide range of specialized and tailor-made products and services with great quality while finding efficiency formulas to contain prices: being receptive in a specific destination; having a network of contacts in different parts of the world that can verify the specific requirements of the client; or being specialized in a specific destination/s, offering tourist packages that have previously been tested by other people with the disability for which it is offered.
