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.

What are the cheapest days to fly?

Frequent travelers may already know this, but earlier in the week can be the cheapest time to fly. 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.

How far in advance can you book a flight?
