Outsourcing has become the next critical business process that needs to be addressed by airlines. Suc-
cessful outsourcing depends on the selection of the appropriate provider. However, this practice is not
always successful and its theoretical justification has not been fully explored. Some significant efforts
have been made based on the transaction cost economics framework. Different from previous studies, we
propose a new hybrid Multiple Criteria Decision-Making (MCDM) model, which combines the Decision
Making Trial and Evaluation Laboratory and the Analytical Network Process (DANP) method. Our model
overcomes problems with previous methods. Our results show that: 1) employees with good knowledge
skills contribute to better service quality; 2) a good relationship between airlines and their partners is the
foundation of a successful outsourcing activity; and 3) risk plays a major role in the outsourcing eval-
uation system, and has the greatest effect on the other dimensions. The model can be extended to other
service sectors.
