Three U.S. airports moved to plate-reading, stop-free parking on different schedules in 2026, and they did not all build the same thing. Knowing which version you are driving into matters, because what you need to do in advance differs.

Alexandria International (AEX), Louisiana

AEX launched a drive-in, drive-out system on January 5, 2026, in partnership with Metropolis, using AI and licence plate recognition so drivers enter and exit without stopping to pay.

What you set up in advance: an account with your mobile phone number, licence plate number, and payment method. You can do this through the Metropolis mobile app, or by scanning a QR code posted in the parking lot.

What happens at the exit: on-site plate readers trigger automatic payment as the vehicle leaves, and confirmation is sent by text to the account holder.

El Paso International (ELP), Texas

El Paso implemented a ticketless system beginning April 8, 2026, also with Metropolis. The AI-based system uses licence plate recognition and mobile payment so drivers enter and exit the airport lots without stopping at a booth or kiosk.

Functionally this is the same model as AEX — same vendor, same plate-and-account approach.

Raleigh-Durham (RDU), North Carolina

RDU is the one that works differently, and the difference is worth understanding before you arrive.

At RDU the entrance gate opens with a QR code, and a licence plate reader opens the gate automatically at exit. The gates are still there. They open without you paying at them, which is the part that feels the same to a driver — but the mechanism is a gate being vended, not a gateless lot.

Practically, that means the barrier is still the backstop. If the plate is not read, the arm does not rise, and you will be dealing with it at the lane rather than receiving a bill afterwards.

What actually goes wrong, and how to avoid it

Register the plate you are actually driving. This is the single largest failure point, and it hits two groups hardest: anyone in a rental car, and anyone who took a different vehicle to the airport than usual. The account is keyed to a plate. A plate that is not on the account is a vehicle the system does not recognise on the way out.

Do it before you fly, not when you land. Setting up an account is easy in the parking lot on arrival and unpleasant at 11 p.m. after a delayed flight with a queue behind you. The QR code in the lot exists for people who did not prepare; use it as a fallback, not a plan.

Check that the confirmation text arrived. At AEX confirmation comes by text to the account holder. If no text arrives after you exit, that is the signal to check the account rather than assume it worked. An unresolved session is far easier to sort out the same week than a month later.

Watch out for a stale card. In a gateless model there is no moment where a declined card stops you leaving. The charge simply fails afterwards, and the first you hear about it may be a notice. An expired card on file is the quiet version of not paying.

Temporary tags and paper plates are a known weak point. Plate readers are built around standard-issue plates. A newly purchased vehicle on a paper tag is exactly the case that generates an exception.

Keep a record of when you arrived and left. In a system with no ticket, you have no artefact. A screenshot of the app session, or simply noting the times, is what you would need to dispute a charge.

Why airports are doing this

The driver-facing rationale is queue time — AEX framed its system as reducing wait times as passenger traffic grows, and the appeal of not stopping at an exit booth after a flight is obvious.

The less-advertised part is that a system without a barrier has no physical way to stop an unpaid vehicle, which is why registration and plate accuracy carry more weight than they did with a ticket. With a ticket, losing it was your problem and it got resolved at the booth. With plate recognition, a mismatch is resolved after you have gone — usually by correspondence.

That is a fair trade for most travellers most of the time. It is worth five minutes before the trip to make sure the plate on the account is the plate on the car.
