I upgraded from an AMEX Delta Gold to AMEX Delta Platinum in May 2010. I had already been issued my $99 companion cert. I just redeemed the cert last month and used my AMEX Delta Platinum to pay for the fare(s) without any problem. I am looking forward to getting my FREE coach companion cert as my AMEX Delta Platinum benefit this year. It's worth more than the cost differential ($150 vs $95) of the cards.
