American Express Platinum has a new benefit, Silver status with Virgin Atlantic. (Centurion gets Gold status, and Virgin is an American Express Membership Rewards transfer partner, so this relationship isn’t suprising.)
Since the signup offer is online, it’s unclear to me what kind of verification takes place that the person signing up is an actual cardholder. I imagine there’ll be a file sent by Virgin to Amex of those who have signed up, and some matching process will likely occur in the future, but all this remains to be seen.
Silver status comes with 2 free upgrades each for the Heathrow and Gatwick Express, a mileage bonus on Virgin Atlantic flights, and Premium Economy checkin privileges when flying Virgin in coach. Not a ton, but better than a hole in the head.
