In the era of digitization, the flow of information, especially negative information, has increased over the years. Reports on undesirable behavior of entrepreneurs, as well as their employees, can spread via social media within several minutes all over the world. Although unethical behavior can be observed in all branches of business, special attention should be paid to the tourism services market. The study presents selected practices in the field of corporate social responsibility of airlines (Easyjet, Ryanair and Wizz Air), and then their ethicality was assessed, which was the aim of the article. Based on the analysis of non-financial case study reports, it was found that airlines' CSR activities focus on caring for the environment. The analyzed airlines are modernizing their fleet in order to minimize the negative impact on the environment, which is reducing carbon footprint emissions. In addition, they use, inter alia, lighter armchairs and serving food and beverages in ecological packaging, while pilots use tablets instead of paper instructions. On the other hand, in activities related to the provision of services, attention should be paid to its optional extensions, which raise doubts as to the ethicality of the manner of their advertising. The website analysis showed that additional services such as paid seat selection or additional luggage are presented as obligatory and thus confuse the customer.
