The Best Time to Book International Airfare – Overview

This year, the best time to buy a cheap international flight to most regions in the world can be summed up in two words: “buy early.” At the same time, quite a few regions of the world aren’t seeing a ton of volatility. So while the “best” price is found close to fare publication date, you can also usually get a “reasonable” fare a bit closer to your travel date.

Keep in mind people increasingly want to travel to international destinations, and the supply to some destinations is struggling to meet demand. In addition, fuel prices are high. Those factors are resulting in higher international airfares than we’ve seen in past years. So shopping early is the best way to get the lowest prices for many locations. Let’s dig in!

The Best Time to Book Flights to Canada

When flights to Canada are published, they’re at their lowest price, on average. But Canada flights aren’t terribly volatile, so if you prefer to wait you can also get a well-priced flight all the way up to around 3 months before your travel dates. Airfares to Canada are about 25% more on average than they were in 2022.

• Best Time to Buy Canada Flights: About 10 months from your travel date
• Prime Booking Window for Canada: About 3 to 10 months before your travel date
• The average airfare: $455

• Cheapest months to travel to Canada: February and March
• Most expensive months to travel to Canada: July and December
• Seasonality for Canada flights: Prices for travel in the spring are where the bargains are seasonally. You can save almost $50 per ticket on average by traveling in the spring rather than the summer.

The Best Time to Book Flights to Mexico

Mexico will be popular as it always is for international travelers from the U.S. In 2023, the best airfare prices pop up early when the fares are published. However, like a lot of international destinations this year, the fares aren’t fluctuating wildly. Buy on the early side to get the best deals, but you can shop around 1.5 months out and still see reasonable cheap international flights depending on your specific plans. Overall, airfares are trending about 10% higher this year over 2022.

• Best Time to Buy Mexico Flights: About 10 months from your travel date
• Prime Booking Window for Mexico: 1.5 to 10 months before your travel date

• Most expensive months to travel to Mexico: November and December
• Seasonality for Mexico Flights: Thanksgiving or Christmas in Mexico are the most expensive times to vacation in Mexico. Don’t wait to shop for your holiday flights.

The Best Time to Book Caribbean Flights

South American airline tickets follow the trend of flights being more expensive than they were last year. Fares are about 13% more expensive than in 2022.

For all seasons, you’ll want to book as early as you can to get the lowest airfare prices.

Cheapest days to travel internationally

When you’re choosing the days you’ll fly, be mindful of any holidays or big events, as that can really impact the costs for your trip. If you can be flexible with your travel dates, even by a few days, you can really save a ton of money and book your cheap international flights.

You should also pay attention to the days of the week you choose to travel. Mid-week flights (Tuesday and Wednesday departures) will usually be a better price point than any other days of the week.
