Aviation is one of the significant forms of business deregulation in Indonesia. The existence
of aircraft makes it easy for passengers to move between regions quickly and efficiently for various
purposes. The commercial air transportation sector is growing rapidly, as seen by the increasing number
of airlines providing flight services and the rising public interest in using these services. However, in
reality, many consumer rights have not been fully fulfilled by airlines, especially in the case of flight
delays. For this reason, strict legal regulations are needed to regulate airlines' responsibilities to protect
consumer rights. In its implementation, it turns out that passengers submit many complaints to the
airline due to various problems. Clear and firm legal regulations are needed to regulate airlines'
responsibilities to protect passengers' rights. This research focuses on two main issues, namely how the
airline's liability to passengers is related to flight schedule delays and how to claim compensation for
airline passengers related to flight schedule delays. This study uses a normative juridical approach by
analyzing laws and regulations related to legal protection for consumers. The data obtained was
analyzed qualitatively to understand the issue more deeply. The study results show that the Regulation
of the Minister of Transportation Number 89 of 2015 expressly regulates the rights of consumers
affected by flight delays and stipulates the obligations of airlines to aggrieved passengers. The
legislation was made to ensure that passengers get safety and security in running flights, as well as
passengers, are more independent and know the importance of the issuance of the law. Furthermore,
the regulation can be used as a foothold for passengers' legal protection against problems.
