Design of a mobile application prototype includes the area of user experience design with the aim to design a simple, intuitive and usable user interface. The purpose of the diploma thesis was to create and design a mobile app prototype for flight booking that would allow the user to easily carry out the process of booking a flight ticket. The whole process of designing a user experience included the research of user needs, that would represent the foundation for building and determining content requirements and structure of our mobile application. The theoretical basis of the thesis, in the area of user experience and user-centered design methods, allowed us to set the foundations for the design of our product. With the market research and the creation of online survey for user research, we were able to determine the requirements and the user needs that the application would have to fulfill. Based on the needs and expectations of our potential users, we designed the structure of our mobile application with the information architecture as our foundation. IA set the basis for the visual design and wireframes, that represented our starting point for the user interface and prototype design. After the creation of the mobile application prototype, usability of our product was tested with the use of the standardized SUS questionnaire. The results of the questionnaire confirmed that our final product has fulfilled user needs, with the simple, functional and visually attractive interface.
