Finding a flight or hotel shouldn't mean checking 47 tabs. Or 3 hours of searching. Or having that feeling you could've got a better deal if you'd just waited a little longer.
So we built something about it. One total price. No tracking. No price that goes up because you looked twice.

Flights and hotels. Both live.
Every airline in the world. Real prices. One function call.
LetsFG gives your AI agent flight and hotel search and booking superpowers. Our server-side engine scans the entire world for the cheapest price. Search is free. Booking is real: the fare is held on your card, a LetsFG booking agent buys the ticket, and you get the airline's PNR.
The same flight costs $20–$50 less because you skip OTA inflation, cookie tracking, and surge pricing.
Claude: LetsFG is in Claude's connector directory: add it there, no URL to paste. Other agents: add https://letsfg.co/mcp as an MCP server. Approving the connection opens letsfg.co/connect: one tap, no card. The card is asked for at your first booking, in a 0.00 Revolut setup (nothing is charged, no Revolut account needed). That token searches for free and books. Scripts: send the same token as Authorization: Bearer to the PFS endpoints. Developer API: a separate paid product for high-volume commercial use; most agents do not need it. → Get started

Real prices: LetsFG vs Google Flights
We searched 5 routes on Google Flights and LetsFG on the same day (2026-08-05), for flights departing 2026-09-16. Same airline, same number of stops — LetsFG was cheaper every time:
| Route | Airline | Google Flights | LetsFG | You Save |
|---|---|---|---|---|
| LAX → Paris (CDG) | JetBlue, 1 stop | $363 | $334 | $29 |
| SFO → London (LHR) | JetBlue, 1 stop | $349 | $333 | $16 |
| LA → New York (JFK) | JetBlue, nonstop | $174 | $157 | $17 |
| London → Singapore (SIN) | Shenzhen Airlines, 1 stop | $395 | $380 | $15 |
| Chicago → Dubai (DXB) | Air Canada + Emirates, 2 stops | $517 | $461 | $56 |
$133 cheaper across 5 routes in a verified comparison (2026-08-05). LetsFG returns the same prices however often you run the search, because it doesn't track you.
Why the difference? LetsFG compares the same flight across many sellers — Skyscanner, Kayak, Momondo, plus airline websites (Ryanair, United, Southwest, EasyJet, Spirit, Norwegian, AirAsia, and more) — and shows the cheapest. No cookie tracking: the same search returns the same prices however often you run it.
Real hotel prices: LetsFG vs Booking.com
Same hotel, same room type, same 2-night stay, same free-cancellation policy — checked on the same day (2026-08-05) for a 2026-09-16 check-in:
