This just in! Airfares offered on Tuesdays tend to be the cheapest, according to flight demand on Travelocity in 2019.

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.
