Regions, not airports
Type a city and you lock one airport. A Klustr unlocks the nearby fields that actually change the fare.
Cluster-to-cluster search
Search regions, not airports.
A Klustr is a region — every nearby airport people actually use — not a single IATA code. FlyKlustr ranks one combined round-trip across both sides so the cheap airport is not the one you typed first.
