I have some of the original Delta certificates and they are about to expire. If you have any left, you should check the expiration dates.

How exactly do these certificates work? Does greenpoints mail them to you and then you send them to the airline to be credited to your account? Or do you have to present them when actually "buying" a ticket with points? Thanks for the info.
