### The Advantage of BC Technology Adoption in the Tourism Industry
#### 3.2.3 Planning of Tourism Activities  
Presently, various industries use BC for the automatization of processes, such as updating discounts, incentives, and rewards. This has huge potential in the tourism sector as well. [PERSON] et al. [30], based on an analyses of thirteen companies' business cases, recommended a BC-based system for the better planning of tourism activities. [PERSON] et al. [31] made the same recommendation by describing a model of a BC-based system containing three kinds of nodes: user, server, and sensor. The nodes interact with each other and exchange information on incredibly short notice. Through this system, sensors provide dynamic data continuously, while users send multicriteria assessment data, and the server contributes the data analyzed by a machine-learning algorithm. Similarly, [PERSON] [32] proposes BC implementation in the tourism sector. With the provided model, the author seeks to support safe travel during the COVID-19 pandemic, and especially for people with asthma. In more detail, through a blockchain-enabled shared-mobility (BESM) architecture, it is possible to control the air quality (using sensors) in transport or COVID-19 circumstances in specific touristic locations and allow tourists on transport or in a city.  
Additionally, BC technology can vitalize the integrated system, where customers find constantly updated transparent and traceable information regarding any service, including hotel availability, airplane tickets, car rentals, etc., by synchronizing the transactions of all the industry actors, and without accumulating the data into a single centralized database. It can also support purchasing health insurance easily thanks to the fastest information flow in the distributed system, as well as exchange travelers' bookings with low costs in the case that they are not able to travel anymore [7]. According to [PERSON] and [PERSON] [33], BC adoption benefits not only customers by providing well-managed services, but also companies by automating the process, cutting the load of routine operations, and thus boosting their overall productivity.  
According to [PERSON] and [PERSON] [34], travel-booking agencies need to shift towards digital innovation in order to adapt to the ever-growing hospitality industry. In this sense, BC technology implementation is a promising way to revolutionize operational processes, and to provide customers with real-time information regarding promotions,product availability, and prices [9; 34]. Indeed, in 2016, Webjet, an Australian travel-booking company, together with several partners (the European travel agency Thomas Cook, China's DidaTravel, Indonesia's Mitra Global, and Singapore's Far East Hospitality) implemented BC technology in order to eliminate the human errors that frequently take place in different phases of booking [7]. Furthermore, by using an integrated system between airplane companies and airports, BC can provide an innovative system to check the path of baggage and avoid it being stolen, loosened, or damaged. Additionally, compatible BC platforms in the different airports would boost this effect, providing comprehensive information, and preventing baggage mishandling or losses between airports. It could save the USD 500 million spent every year by airline companies on solving identified problems [7].  
[PERSON] and [PERSON] [35] argue that there are still no BC-based smart tourism solutions that would cover all the aspects of the sector and solve the fundamental challenges of the tourism industry, or they are only conceptual. Therefore, the authors propose a BC-based smart tourism platform named BlockTour. This seeks to address the challenges and provide a specific solution through the development of a real-world prototype. BlockTour helps to link tourists to the tourism companies in a secure and reliable way. The testing phase illustrated the practicability and high performance of the platform.
