Smart clusters
SoCal, Hawaii, New York, Europe — popular Klustrs for how people actually travel.
Cluster-to-cluster search
Search regions, not airports.
Compare every nearby airport on both sides and surface the real lowest fare — not the one a single-airport search hides.
Custom radius
Drop a pin on any city and pull in every commercial airport within 30, 50, 80, or 100 miles.
No-frills first
Personal item only. No seat. Basic economy. Ranked for travelers who want the number, not the extras.
