I had a pretty simple query: &quot;What&#x27;s the cheapest flight from my airport to any given airport in Japan for the next 12 months?&quot; I didn&#x27;t care which city I was heading to because I planned on visiting quite a few cities and they&#x27;re all connected by the Shinkansen. I didn&#x27;t care about when I&#x27;m leaving because my dates were flexible.<p>Skyscanner was the only one capable of answering my query. All the competition required me to provide a specific destination and the approximate travel date for any searches.
