Safety performance can be increased if cabin crew management understands the real situation in the operation area. The exposure on the operational area gives the cabin crew valuable insight that can be used to enhance the safety management system, policy and mitigation. Therefore, management must be able to encourage the cabin crew to communicate safety-related information. Therefore, the cabin crew management must find the factor to enhance cabin crew prosocial voice behavior and upward safety communication. The objective of this study is to examine the influence of benevolent and morality leadership on upward safety communication and prosocial voice behavior in Indonesian cabin crew. The aim of this study is also to investigate the role of perceived organizational support (POS) in the relationship between benevolent and morality leadership with upward safety communication and prosocial voice behavior. Using the Structure Equation Model (SEM) and 356 cabin crew respondents, the result showed benevolent and morality leadership has a positive influence on upward safety communication. Another result is benevolent leadership has a positive influence on prosocial voice while morality leadership has not a significant influence on prosocial voice behavior. The last finding is POS mediates the influence of benevolent and morality leadership to prosocial voice behavior and upward safety communication.
