In single-aisle aviation industry, aircraft manufacturers are now fully transitioning to reengineered aircraft types with more efficient power plants, which provide significant environmental advantages. However, the extent to which the customers of various airlines value the availability of remotorized variants of famous aircraft is unclear. We explore passengers’ ticket purchasing behavior in connection to aircraft types, airlines, ticket pricing, and individuals’ degree of fear of flying in this research. We discover that airline selection is mostly determined by ticket price and that a fear of flying has limited impact on consumers’ choice of one airline over another. Individuals who have a significant fear of flying prefer larger aircraft, particularly if the ticket price is high. When the same fearful passengers fly in smaller planes, they seem to shun reengineered aircraft models. Avoiding certain aircraft models seems to be linked to a choice mechanism characterized by a minimum threshold of acceptable familiarity with ticket features on the part of the passenger. If an air ticket has features with a level of unfamiliarity past this threshold, the passenger selects a different alternative.
