What is the best day to buy a plane ticket?

This just in! Airfares offered on Thursdays tend to be the cheapest, according to flight demand on Travelocity in 2020.

In 2020, flights departing on a Monday 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.
