Believing that there is only an optimal day a week to save on flights, and that day is Tuesday, it is a legend. And like all good legends, there is something really … but it’s not the whole story.
The reality is that flight prices constantly change every time of the day, adjusting to the demand in real time. The airlines are not refused the same day every week, as a grocery store, so you will not find offers waiting until Tuesdays to book. However, you may find some modest savings if you are willing to fly On Saturdays or half of the week, when there is less demand than usual.
This is what the data shows in the best days to reserve a flight and when to fly.
The best day to book a flight
You can find offers any day of the week since flight prices fluctuate with demand. That said, the data provided to Nerdwallet by Expedia indicate that, if it has flexibility on when to reserve, Sundays are generally the best.
National travelers can save 6%, while international travelers can save 17% compared to the reserve on a Monday or Friday, according to the Air -Expedia Trips Hacks Report.
Airlines can offer sales, increase the amount of seats on a route or even lower prices to coincide with a competitor, so there is no real pattern at what day of the week the best offers has.

Fly on vacation (or as far as possible)
Holidays are a completely different beast, regardless of whether it is July 4 or Labor Day. In general, there are more people flying in the days around a vacation, so there are fewer aircraft seats and higher prices.

Because many airlines have flexible cancellation policies, it is worth ensuring a decent rate in advance and re -reserve if the price of the flight falls in later months.

Tips for finding cheap flights any day of the week
National flights: book one to three months in advance
Although no day of the week has cheaper flights, there is a period of time during which you must book before prices upload.
Reserve national flights from one to three months in advance to avoid any price increase in the weeks prior to the departure date. In fact, national flights reserved one or three months in average anticipation of 25% less than last minute agreements, according to Expedia. Last minute flight offers are not very common and runs the risk of not getting a seat because their desired flight could be exhausted.
International flights: book two or eight months in advance
If you are flying internationally, you will want to look at two to eight months.
It is no longer necessary to look at flight prices before the ideal reserve window. Google flights, for example, are sometimes shown in search results when they expect prices to be the lowest based on historical data for their route.

Establish a price alert
Let a computer program do the job for you. Instead of verifying flight prices every day, establish a price alert in the travel search engine of your choice, either Google flightsHopper, Skyscanner or Kayak. They will send an email when they see the price fall.
Reserve if you find a cheaper price
First, you will have to make sure that the original flight you reserved does not have change or cancellation changes. For most airlines, that applies to most main tickets and premium class on national flights and some short -distance international flights. In general, you cannot change or cancel basic economy tickets for free.
If you can cancel or change without rates, establish a price alert. When the price falls, you can cancel your flight and reserve again (on the same airline or a different one) to get the cheapest price. Keep in mind that you can only get a voucher or travel credit if you cancel, so you should only use the option if you are quite sure you will fly again with the original airline within a year.
Be flexible with destination, airport and dates
The golden rule of cheap travel remains: Be flexible. Use Google flights to see if there are cheaper places to go to the target field when looking. Verify nearby airports if you are configured in a destination and use calendar views to find lower prices on different dates. Maybe he adopts a long scale as an opportunity to see another city on his trip.
After all, the best day to reserve a flight and the best day to fly is when it is cheaper, and that could vary depending on when where it goes.
