Yes, you can. While purchasing tickets from copa.com, you are allowed to put your flight booking on hold. Choose the “Reserve and pay later” option and the airline will keep your Copa Airlines reservations active for the next 24 hours. You got 24 hours to make payment for your booking. Move to the “Manage booking” section later and use your credit card to pay for your reservation. Copa Airlines will only put your Flight booking on hold if you are registered and are logged in to your account. If you will not pay within this 24 hours period, then your reservation will expire automatically.
