Demo: LetsFG vs Default Agent Search
Side-by-side comparison: default agent search (OpenClaw, Perplexity Computer) vs LetsFG CLI. Same query — LetsFG finds cheaper flights across 150+ airlines in seconds.
Why LetsFG?
Flight websites inflate prices with demand tracking, cookie-based pricing, and surge markup. The same flight is often $20–$50 cheaper through LetsFG — raw airline price, zero markup.
LetsFG works by finding the best price across the entire internet. It fires 150+ airline connectors in parallel, scanning carriers across Europe, Asia, Americas, Middle East, Africa, and Oceania — then merges results with enterprise GDS/NDC sources (Amadeus, Duffel, Sabre, Travelport) that provide competitive pricing from 400+ carriers including premium airlines like Lufthansa, British Airways, and Emirates. The best price wins.
