Three steps, about a minute

You don’t need an account. We ask the airline to hold the seat before you pay anything, so you never pay for a booking that doesn’t exist.

  1. Where, when, and your name exactly as the passport shows it.

  2. $12 for one reservation, or $29 a month for as many as you need. Card, Apple Pay and Google Pay all work.

  3. The airline’s booking code and your itinerary land in your inbox. Look it up on the airline’s site whenever you like.

The document you hand over

Built from the airline’s own record: your name, your flights, and a booking code any officer can look up for themselves.

Questions people ask

Is this allowed?

Yes. Airlines routinely hold seats without payment for a set time. We ask for that hold in your name; the fare is simply never paid.
