The Worst Day to Buy a Plane Ticket Is a Friday, Study Reveals

The worst day to buy a plane ticket is a Friday, according to analysis of worldwide ticket prices.

The study revealed plane tickets bought on Fridays are 13% higher than those on Sunday.

The reason behind the spike in ticket prices is believed to be that those taking holiday tend to book discount trips on weekends, while those flying for business purposes tend to book at the end of the working week.

Airlines Reporting Corporation told The Wall Street Journal that flights within Europe should plan to buy their tickets 140 days in advance if they wish to get the cheapest ticket, while those purchasing domestic flights within the U.S. can buy theirs 57 days in advance.

Rick Seaney, chief executive for FareCompare, told the newspaper that it is possible to "buy too early".

Airlines will not start to actively manage the price of fares until about five or six months in advance for international trips, meaning buying any time before then could result in an increased price.
