You've never heard of this "rule," but it's one of the most widely held flight myths. According to Travohelp, the average fares bought on each day of the week were virtually identical, and Hopper discovered that Tuesday was the cheapest day to buy a flight for just 1.6 percent of domestic routes. While many airlines used to schedule their sales on Tuesdays — and competitors would match and compete on the same day, into Wednesday morning — the explosion of tools through which people can get information these days means “any day can be an airfare sale day,” according to Saglie.
According to the Travohelp analysis, the cheapest days to fly are Tuesday and Wednesday, and the best flight deals are found in January, followed by February; by summer, flight prices have risen sharply.
• According to some experts, if you want to book a cheap flight, you should do so on a Tuesday afternoon.
• On Mondays, airline executives examine how seats sold over the weekend and determine what the airfares should be. They look at what rivals charge for routes on Tuesday mornings and adjust their fares accordingly.
• They've settled on the most competitive prices by the afternoon, which is why plane tickets are the cheapest on Tuesday afternoons. Prices tend to increase again by Friday, so buy between Tuesday and Thursday.
• Nonetheless, airfares are determined by demand. The more available seats on a flight that an airline has left, the more expensive those seats will be.
• So, if you're going to book a flight home for Christmas, it's probably not a good idea to wait until Tuesday afternoon if you find a reasonable price, as such flights are usually in high demand.
It turns out that the time you buy airline tickets is less important than the time you use them. Is Tuesday the best time to book a flight? Flights departing on Tuesday or Wednesday are actually less expensive. Data reveals that flying out on Wednesday is the least expensive, with Tuesday a close second. According to the most available data, a plane ticket costs about $73 less on Tuesday or Wednesday than any other day of the week. Tuesday is the cheapest day to travel, with average fares of $301. At $304, Wednesdays are a close second. By far the most expensive day to fly is Sunday, which costs $398.
The other days' fares range from $340 to $364, which is unlikely to tempt you into a less-than-ideal itinerary just to save a few dollars. However, this demonstrates that when looking for the best deal, you should consider your travel dates rather than the date you're hitting "book."
Do flight prices go down on Tuesday? In simpler words, Tuesdays at approximately 3 pm eastern time, Many U.S. airlines start airfare sales late Monday or early Tuesday on their websites; the competition then matches these newly reduced prices, and the process is usually completed by Tuesday afternoon. When shoppers have the most deals to choose from, this is the time to go.
