No, it's not necessary that airline tickets tend to be cheaper if you purchase them at night. The price of airline tickets can change frequently based on various factors like demand, the time of year, and how close the travel date is.

According to a study by Expedia, the cheapest day to book flights is Sunday. When comparing Sunday flight prices to Friday, Expedia found that travelers save 5% on domestic flights and 15% on international flights. Sunday has been the best day of the week to book flights since before 2020.

Typically, the lowest prices are made available earlier in the week, and the highest prices are offered later in the week. This is why the answer to the question, “When do flight prices go down?” is sometimes… a Tuesday! When are flights cheapest during the week? Midweek.

Timing is everything (kind of)

Generally, the best prices tend to drop off once the flight is less than three weeks out. If it's 21 days before you plan to travel and you haven't seen a flight deal to your destination, go ahead and book.
