The development of the aviation industry, particularly in the implementation of the Hajj pilgrimage, encourages airlines to implement various clauses in transportation agreements, one of which is the non-refundable clause. The problem faced is how to provide legal protection for those who suffer losses due to the implementation of non-refundable clauses in flight tickets. The type of research used is normative juridical legal research. The results of the study indicate that non-refundable clauses in air transportation agreements are problematic. Non-refundable clauses in flight tickets are standard clauses that have the potential to harm consumers because they eliminate the right to a refund. Decision Number: 310/Pdt.G/2023/PN Jkt.Brt emphasizes that legal protection for consumers can be realized in court through an assessment of the validity of the clause, in order to create a balance of rights between business actors and consumers.
