This just in! Airfares offered on Tuesdays tend to be the cheapest, according to flight demand on Travelocity in 2019. Wednesday and Friday prices are also good, but you may want to prepare your budget if booking on a Monday, as data shows the start of the week is when prices are generally at their highest.

Frequent travelers may already know this, but earlier in the week can be the cheapest time to fly. In 2019, flights departing on a Tuesday were generally the cheapest of the week, whereas you may pay a premium for weekend flights when demand is usually high. On average, tickets were most expensive for Saturday departures, so if you need to fly out on a weekend, you might look for deals ahead of time.
