Historically, travellers have been advised to book flights on Tuesdays to get the best flight deal. And there was a time when this was true. A decade ago, airlines generally launched new sales on Tuesdays, and airlines were generally quick to match each other’s prices. This could lead to cheap flight deals on Tuesdays. That is if an airline launched a new sale.
However, this advice no longer holds true. Airlines don’t just release sales on Tuesdays, and airlines don’t always match their competitors’ sales. Now, the advice on what is the best day of the week to buy airline tickets depends on which study you read.
According to a 2021 study by Expedia, the cheapest day to book flights is Sunday. When comparing Sunday flight prices to Friday, Expedia found that travellers save 5% on domestic flights and 15% on international flights. For the past four years, Sunday has been the best day of the week to book flights.
Another 2022 study done by Google that looked at trips departing from the top 4,000 markets in the U.S. found that flight prices on Tuesdays, Wednesdays and Thursdays were 1.9% cheaper on average than flights on Saturdays and Sundays. However, Google’s conclusion in releasing its study results: “There isn’t much value in purchasing your tickets on a certain day of the week.”
We concur with this advice. The best day of the week to buy airline tickets is the day when a flight deal pops up. And that will not be reliably on one day of the week or another.
