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.</font>
Greenpoints mails you a certificate, which you then fill out and mail to the airline. It is a blank certificate, so you can spread them amongst different family accounts or transfer them to others.
