Approve

Nothing is booked until you approve it.

Your AI can't book on its own. LetsFG e-mails you the flight, the travellers and the price with one Approve button, and only you can press it. Once you do, your fare is held on your card and only taken when the airline issues your ticket.

To book, add a card on this secure page. Never type it here.

Got it: Visa ending 4242. That's all I can see.

Your AI never sees your card.

You add your card once, on a secure page, never in the chat. Only Revolut, our payment provider, ever sees your card number: not your AI, and not LetsFG. Your AI just sees the brand and the last four digits, and it can't change your card: that only happens through your e-mail.

Never fill in a checkout again.

Your AI does the whole checkout for you: the booking page, the security checks, every form, only the extras you asked for. If the price jumps, it checks other sellers and asks you first. You just watch, and get your booking reference.

Questions, answered.

Everything people ask before they let an AI book for them. Still unsure? Write to contact@letsfg.co, a real person answers.

Why can't I search on the website anymore?

Because we believe travel was supposed to set you free, not lock you in front of a website for two hours. We make your AI do the work, completely. You just approve and experience, hassle-free. That's our mission.

Is it safe to let an AI book for me?

Your AI can't book anything on its own. Before every booking, LetsFG e-mails you the flight, the travellers and the price with one Approve button, and nothing is held or charged until you press it. Only you can.

Does my AI see my card?

No. You add your card on a secure page run with Revolut, never in the chat. Your AI only ever sees the brand and the last four digits, and your card details are never passed to the airline or travel site either.

When is my card charged?

When you approve, the fare is held on your card, not taken. It's only charged once the airline confirms your ticket. If you add a bag or accept a higher price later, that's held separately, and only after you say yes.

What if the price goes up while it's booking?

It stops and asks you first, and checks other sellers for the same flight. If you say no, or don't answer, nothing is bought. We cover tiny differences of up to 0.5%, so you're still only charged what you approved.

What if the booking fails after I've approved?

You're not charged for a ticket you didn't get. Either the hold is released (your bank can take a few days to show it), or, if the automatic booking hits a wall, a person on our team takes over while your fare stays on hold, and we tell you what's happening.

Who am I actually booking with? Is the ticket real?

Yes, it's a real ticket in your name. LetsFG books it for you, as your agent, with the airline or a travel site, and tells you which one before you approve. You get the booking reference (PNR), and the e-ticket goes to your e-mail. Check spam just in case.

Can I cancel or change my flight?

Flight changes and cancellations go through the seller, under your fare's rules. Want room to change your mind? Ask your AI for refundable fares. Refundable hotel rates can be cancelled before their deadline, and you get back the share shown on the rate (about 90–94%, the rest is our fees).

Why do you need my passport, and where does it go?

Some sellers require it to issue your ticket. We ask for it once, so every booking after that is just one click. It's stored encrypted and only goes to the seller of a booking you approve.

Do I have to pay to search?

No. Searching is free, in your AI and on letsfg.co. You only pay for a booking you approve.

Which AI assistants work with LetsFG?

Muse, Claude, ChatGPT, Grok, DeepSeek, and any assistant that accepts a custom plugin, connector or MCP. You connect once and sign in with a one-time code sent to your e-mail. There's no password to remember.

I didn't get the Approve e-mail. What now?

Check your spam folder first. The Approve button works for 15 minutes, so if it has expired, just ask your AI to book it again.
