Is Tuesday Still the Cheapest Day to Book Flights? Myth or Fact?

For years, we’ve been told that Tuesday is the best day of the week to book a flight. We’ve used this information in the past to try to fine-tune the optimal air travel rate. However, new information published by Dollar Flight Club on July 16, 2026, suggests that the familiar “Tuesday rule” is no longer a dependable way to find the lowest airfare.

According to Dollar Flight Club, there is now no single day of the week that consistently produces the cheapest airline tickets. Sunday may offer a slight statistical advantage, with reported average savings of about 6 percent on domestic flights and up to 17 percent on some international fares. Friday can also occasionally be a favorable booking day.

But the more important finding may be that the day you travel often matters more than the day you purchase the ticket.

The Cheapest Days to Fly

Tuesday and Wednesday are frequently among the least expensive days to depart. These midweek days often attract fewer business and leisure travelers than Mondays, Fridays, and weekends.

Dollar Flight Club reports that Tuesday domestic departures may cost approximately 14 percent less than Sunday flights. Wednesday can be particularly favorable for international travel, with some midweek departures costing 10 to 30 percent less than weekend alternatives.

These percentages will not apply to every route, but they reinforce a useful travel-planning lesson: checking flexible dates may yield greater savings than waiting until a particular day to book.

When Should You Book?

The number of days before departure may also have a greater effect on airfare than the weekday on which you make the purchase.

For many domestic trips within the United States, Dollar Flight Club recommends booking approximately 30 to 45 days before departure. Waiting until the final two weeks can be expensive, as fares may rise by 20 to 30 percent.

International trips generally require more advance planning. A broad booking window of two to eight months is suggested, with Europe often falling within a two- to six-month range and many trips to Asia requiring four to eight months of advance planning.

Holiday travel, spring break, and other high-demand periods may require booking even earlier.

Fare Alerts May Be More Useful Than Waiting for Sunday

Because airline prices can change throughout the day, fare alerts may be more effective than waiting for a supposed “best” booking day.

Travelers can improve their chances of finding a reasonable fare by:

• Setting flight-price alerts several months before traveling
• Comparing nearby departure and arrival airports
• Searching for flexible travel dates
• Checking the total price after baggage, seat, and other fees
• Establishing a target airfare before beginning the search

Moving a trip by even one or two days can sometimes produce a meaningful difference in price.

Our Takeaway

Sunday may currently offer a small booking advantage, but travelers should not replace the old Tuesday myth with a new Sunday myth.

The better strategy is to begin tracking fares early, travel midweek when practical, and book when the price fits your budget within a reasonable booking window.

In other words, the day you fly may matter more than the day you click “buy.”
