This just in! Airfares offered on Thursdays tend to be the cheapest, according to flight demand on Travelocity in 2020. Wednesday and Friday prices are also good, but you may want to prepare your budget if booking on a Sunday, as data shows the end 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 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.
Trying to figure out how early you should book your flight? It's possible to start comparing international airfares on Travelocity up to 12 months in advance. However, it does depend on the carrier as not all airlines release their prices that far out. According to our 2020 flight demand trends, last minute planners can still bag a bargain with some of the cheapest fares appearing 2 weeks to 2 months prior to their travel dates.
We'll let you in on a secret...You can save big on flights if you mix and match your airlines and fare types. In fact, travelers who booked flights on Travelocity in 2020 saved nearly 40% when their return flights consisted of two different airlines or fare types.
*According to flight demand on Travelocity.com from January to December 2020. Savings are subject to change based on departure location, date and destination.
