Abstract: With the trend of the humanization of international law, aviation litigation caused by product liability is a very important means to protect consumers’ interests. Such researches on judicial activities of product liability have theoretical and practical significances. At present, there are few studies on this issue at home and abroad, while problems in practice and applicability exist. According to the current state of the studies and judicial practices in this field at both home and aboard, the paper puts forward that some legal effects that are involved with product liability should be introduced into international air transportation proceedings. Under the basis of balancing product manufacturers, airlines and consumers, focusing on protecting human rights and respecting human life value, it should give preference to the protection of consumers’ interests of air transportation.
