South America

If you want to take a holiday in South America, the best time to buy a flight from the US is, on average, 110 days before travel. But, that doesn’t mean you have to wait for that day. The full prime booking window runs from five to 11 months before departure and the average airfare is about US$845. When you will actually fly also has a big impact. The cheapest month to travel is February and the most expensive is December.

Asia

Dreaming of a trip to Asia? Plane tickets are cheapest around four months, or 120 days, in advance. Overall, there’s a very large prime booking window for Asia, ranging from over one month to seven months, so you can check back often to try and score a deal. The cheapest month to travel is in November, while the most expensive month is June. According to CheapAir.com, travelling in November could save you as much as US$420, but since Asia is such a huge region, it’s best to do some of your own research before you settle on a price.

Europe

The best time to book that dream holiday to Europe is about 160 days before travel. But, since you have between 1.5 months and just over eight months to get the optimal price, there’s time to watch for deals. July is going to be the most expensive time to go, since it will bring the best weather to the continent, but if you want to chance the forecast, travelling in March will be on average about US$371 cheaper.

South Pacific

If you want to travel to Australia, New Zealand or the South Pacific, preparation is key; the cheapest time to buy is 197 days before travel. But, you do have between 54 days and just over eight months to get the best price. Since December is summertime in the southern hemisphere, prices will be about US$550 higher than average the cheapest month of May. That makes a big difference when the average airfare is US$1708.
