Your window is closing.

That is, your “Goldilocks Window” for buying flights to Europe is rapidly narrowing. If you’re planning a European adventure this summer and haven’t purchased flights yet, well, close this blog post and head on over to Google Flights.

What is the ‘Goldilocks Window’ for Flights?

The Goldilocks Window is the time period in which flights are most likely to be at their lowest. For transatlantic flights to Europe, the window is a gargantuan 2-8 months in advance.

While that window covers practically the whole year, I can speak with certainty that this window is MUCH SMALLER when it comes to summer travel. And during peak season, you’ll want to err on the longer end of that timeframe. I recommend booking at least 4 months in advance for European summer travel.

So…

Planning to visit Europe in August? Book your ticket by the end of April. Otherwise, your chances of getting a great deal (or any ticket within the realm of affordability) decrease significantly.

Goldilocks or not, don’t let this window close if you’re still standing outside!
