“The day of the week I travel does not affect the cost.”

Expedia has “broken” this myth when confirming on Fridays and Saturdays are the cheapest days to leave.

They said: “It is not only when you reserve, it is when you fly. International travelers who leave on Friday can save up to 14%.

“On the domestic front, Saturday is the cheapest day to fly: transvestins can save up to 18% compared to flying on a Monday, which is the most expensive day to travel.”

Cheaper day to book a flight

“The day of the week that I reserve my flight does not matter.”

Discrediting this myth of its report, Expedia has discovered that the reservation on a Sunday can “keep more in your wallet.”

“Reserve on the right day can mark a world of difference. Travelers who reserve Sundays can save up to 21% on national flights compared to Monday, and up to 22% on international flights compared to Friday, ”explains the travel expert.

“The later he will book, the cheaper it will be.”

From 13 to 21 days it is the “magic window”, shares expedia.

“The reserve too anticipation can cost travelers. The reserve of 13 to 21 days before its international flight is the optimal point for savings, up to 8% less than those reserved two months before.

“National flights are more affordable when reserved 170-180 days before the trip, saving up to 36% compared to leaving it until the last minute (6 – 12 days outside).”

“Premium tickets are always too expensive to consider.”

Expedia has crushed this “myth”, stating that the premium rate is now lower than in 2019.

“January is the cheapest month to travel in Premium classes, and October is the most expensive: traveling on the premium in January instead of October can save 19%.”

Melanie Fish, Expedia Brands spokesman, commented: “It is intelligent to take into account the 2025 air hacks when reserving flights, but the best hack is to let technology find the best value.

“Configure the Expedia flight price tracker in the application. He notifies you when flight prices change and use data to help you decide when to book. ”

She added: “Sunday is the cheapest day to reserve its flight, being Friday the best day to travel, and reserve too far can cost money: these realities fly in front of the advice that float on the Internet.

“It makes sense to trust the billions of data points around the world and each airline that enters the Expedia Air Hacks report.”
