A weekend in Lisbon, booked from ChatGPT, Claude, Muse or Instinct. Your agent searches Ona, holds the seats, and you pay on one secure page.

Illustrative preview with example prices. ChatGPT, Claude, Muse and Instinct belong to their makers.

In the preview you message your agent: Lisbon this weekend, aisle seat, under €500, somewhere walkable. It searches Ona and suggests TAP flight TP 1351 from Paris on Friday at 07:25, seat 14C, for €212, and two nights at Casa do Largo in Alfama for €256: €468 in total, held for 12 minutes. You say book both. Your agent sends one secure link, you pay €468, and the agent confirms booking OA-7K2Q with the e-ticket and hotel voucher in your inbox.

Before you board

Good
questions.

Is it free?

Yes. Your Ona account is free, and you don’t need a card to sign up. You only pay for the trips you book, at the price on the payment page.

Which AI apps work?

ChatGPT and Claude, plus Claude Code, Codex, Cursor, VS Code with GitHub Copilot, Gemini CLI, Goose, Hermes and OpenClaw. Agents that browse the web, like Muse and Instinct, book on book.onarrival.com. ChatGPT needs a Plus, Pro, Business, Enterprise or Edu plan, on the web. Claude’s Free plan includes one custom connector.

Does my agent see my card?

No. Your agent sends you a link, and you pay on Ona by OnArrival’s secure checkout, powered by Razorpay, with UPI, cards or netbanking.

When is my trip actually booked?

Only when you pay. Your agent holds the fare for 12 minutes while you decide. If you don’t pay, nothing is booked and you aren’t charged.

What if my plans change?

Every booking is in your Ona account. Message our team from there, or from support, about changes, cancellations and refunds.

Who is Ona?

Ona by OnArrival, a travel booking company from Bengaluru. You can also find us at onarrival.com.
