7. How do I get a receipt?

After you pay with cash or credit card at the Pay & Go machine, you can print a receipt if desired. Be sure to get one at the Pay & Go machine because receipts are not available at the Pay & Go exit lanes.

8. What if I have a problem making payment at the Pay & Go machines?

There is a blue "i" button on the front of each machine. When pressed, you will be connected to a customer service representative who will assist you in operating the machines. Should you continue to experience difficulties, you will be directed to a cashiered exit lane, where a cashier will assist you in making payment for your parking. In addition, customer service representatives will be available in the Main Terminal in order to assist you. Look for their white shirts with the Pay & Go logo.

9. What do I do after I pay for parking at the Pay & Go machines?

Once you pay at the Pay & Go machines, take the ticket that the machines return to you and go to the exit plaza. Drive to a Pay & Go lane and insert your ticket into the exit machine. The machine will recognize that you made payment at a Pay & Go machine and raise the gate so you can be on your way! Please note that you will not get your ticket back at the Pay & Go lane once you insert it.

10. Can I still make payment at the exit plaza?

Yes, you can still pay at a cashier booth in the exit plaza in each parking facility. However, the number of cashiered exit lanes has been reduced to accelerate the exiting of patrons using Pay & Go. The Terminal / Hourly and Economy Lots each have three cashiered exit lanes and the Garages each have two.

11. How does the machine in the Pay & Go exit lane know that I already paid?

The Pay & Go machine encodes your ticket with your payment information and returns the ticket to you. The machine in the Pay & Go exit lane will read the encoded information on this ticket and recognize that you paid.

12. What if I forget my ticket in the car?

You will be unable to make payment for your parking at a Pay & Go machine without your ticket. If you forget your ticket, proceed to a cashiered exit lane. Remember to keep your parking ticket with you on your next visit.

13. How long do I have to exit the lot once I pay in the Main Terminal?

A specific number of minutes, called a "grace period," are set for each parking area. The grace period allows sufficient travel time to get to the parking area on-foot or via a shuttle bus, as well as adequate time to proceed to the exit plaza. These times have been determined based on average passenger exit times for each parking area. Should you exceed this grace period, you will be prompted to pay an additional fee at the exit lane using a credit card.

14. How can I get more information?
