Temporal Changes of Airfares Toward Fixed Departure Date

Despite the existence of numerous published articles that examined the online fares for air-tickets, no prior studies have investigated the issue of temporal changes of airfares toward a fixed departure date. In other words, consumers have no knowledge of when the best time is to purchase their lowest fared air-tickets from the Internet. This study investigated the daily changes of fares for return air-tickets on five online travel agency (OTA) websites with fixed dates of departure during shoulder and high seasons. Empirical findings showed the lowest airfares from Hong Kong to Beijing and Bangkok, representing two most popular short-haul travel destinations, were not found at the initial stage of the data collection period. In other words, consumers should not make online purchase of air-tickets too early.
