Skyscanner does a very clever thing where if you place a specific query, it&#x27;ll pass it on to the providers it searches, but it will also cache the result of your search internally and give you estimates for wider-ranging searches.<p>For instance, you can ask: &quot;what&#x27;s the cheapest flight from Country 1 to Country 2 over the coming year?&quot; and it&#x27;ll use its internal cache to give you suggested arrival&#x2F;departure airports and times that you can then combine with local transportation on your own. I&#x27;m not aware of any other site that offers this.
