This paper aims to systematically review the literature related to the estimation of air ticket price elasticity and conduct a meta-analysis to examine the effect of various determinants of ticket price elasticity estimates. A total of 258 estimates of air ticket price elasticity of demand were collected from 44 international studies from 1974 to 2020. Meta-regression models were developed, including fixed effects and random-effects models. The independent variables of the meta-regression are related to various geo-economic (coverage area, flight distance, passenger category, etc.) and study-descriptive characteristics (data time period, publication type, etc.) of each individual sample estimate of the reviewed studies. The results indicate the significance of several determinants such as fare class, flight distance, the study’s publication type and the demand model’s characteristics on the estimated ticket price elasticities.
