"Effective January 8t, 2019
cash payments will no longer be accepted at Air Canada airport counters
in the United States. Customers will have the option of paying for tickets as well as baggage and other fees with any major credit.
A reminder that you have the option to pre-pay baggage and other fees online at time of check-in from 24 hours before your flight up until the check-in deadline.
Air Canada went cashless for in-flight purchases several years ago. We are now doing the same at the airport, creating a faster and more efficient airport experience for our customers. In fact, you may already know that the Air Canada counters at the following Canadian airports are already cashless: Calgary (YYC), Edmonton (YEG), Ottawa (YOW) and Winnipeg (YWG).
Cash conversion to a prepaid credit card
If you don't have a credit card, ReadySTATION kiosks are available at most airports and offer
cash conversion to a prepaid credit card.
Where such kiosks are not available, an alternative solution is to purchase a prepaid credit card at the Airport Currency Exchange or at other convenience stores. If you do choose this option, please make sure to keep your prepaid credit card (even if its value has reached zero) until all travel associated with the card has been completed. In the event of a refund, this will allow us to return the amount to your original form of payment."
