You can put your reservation on hold in Copa Airlines. For this, you will have to simply select the option of “Reserve and pay later” on the official website, and this will keep your reservation active for 24 hours. You will get ample time to make the payment. You can use this reservation for later by using the credit card in the “Manage your booking” section.
For more information, you will only be allowed to put your reservation on hold if you are registered with Copa, and you have logged onto your account. If you don’t pay for your reservation within 24 hours, it will expire automatically.
