Free. Everywhere you need one.
Smarte Carte runs the trolleys across all four terminals and they are free. The same company charges $9 at Miami and $8 at LAX. The price is set by the airport, not the vendor.
Where the carts are, in the order you meet them
| Step | Where | State | What it costs | How you pay | Confidence |
|---|---|---|---|---|---|
| 01 | Departures Check-in and the forecourt | Free | Nothing | The airport pays | high |
| 02 | After security Between security and the gate | Free | Nothing | The airport pays | medium |
| 03 | Baggage reclaim Where you collect your bags | Free | Nothing | The airport pays | high |
Usable after security, unlike almost every Western airport in the set.

Keep it honest
The after security figure is the weakest on this page. If you have been through recently, that is the one worth a photo.
