Abstract:
The objective of this research was to consider the importance of weighting factors for airline services
in domestic. This study was the mixed method between a quantitative and a qualitative approach. First, we
collected the factors from past research and marketing and did an in-depth interview with seven customer
service airline staff who experienced more than 10 years. The questionnaires were then developed to
evaluated Item-Objective Congruence Index (IOC) for factors from the same sample group as the first step.
The results of this study showed that five factors which obtained Item-Objective Congruence Index from
the 0.05 level were as follows: process, safety, staff services, ticket price, and physical characteristics. The
interview from twenty-five passengers who flew by domestic more than 60 flights within 5 years was done
using the analytic hierarchy process (AHP). The results were revealed sequentially from the most important
weighting factor to the least important weighting factor, as shown: staff services, process, safety, ticket price,
and physical characteristics, respectively.
