Those seem to be the terms listed on the Amex website, if you were applying for a new Delta Amex credit card. But the T&C of the certs on my existing credit cards say A&I. I received a new cert about 2 weeks ago and the T&C again said A&I. I used the cert yesterday. Even though Z was available for the flights I purchased, the website bumps the classes up to I.
Do the T&C on your cert actually say Z or are you calling in so the Delta agent can override the A&I restriction to book in Z?
