“We find that when you control for a large set of factors – the day-of-week of travel, whether the ticket was refundable, the number of days in advance that the ticket was purchased, how full the flights were, and other factors – that tickets purchased on the weekends were sold, on average, for a 5 percent discount,” Puller explains.
Now that this is publicized, will changes in purchasing behaviors make it disappear? There are a couple of reasons why not. First, since most consumers are not known for consulting academic journal articles before they shop, this information may not disseminate much. Second, it may not be worth it for business travelers to work on weekends just to get these price decreases.
