The chapter explores existing consumer protection legislation based on Article 114 TFEU, with a focus on digital markets. It describes the complex relationship between internal market building, on the one hand, and consumer protection, on the other. Attention is paid to the contested idea of “consumer confidence” and to the very notion of consumer. The analysis supports an extensive EU competence to enhance the protection of travellers contracting via online platforms. As the review of prior legislation shows, despite notable measures taken—such as, most recently, the Digital Services Act—a comprehensive approach to online travel platforms is not yet in sight.
