There is a new design available for the American Express Delta SkyMiles Reserve card. It is made with 25% metal from a retired Boeing 747 aircraft. Here is one of many articles with more details. Delta and American Express begin issuing cards made of Boeing 747 metal | CNN Underscored.
New applicants can get this card and there bonus is increased to 110,000 Delta SkyMiles thru 8/3/22.
I did my own chat with Amex to make sure that this card was available for existing cardmembers (not just new applicants).
It is!
In fact, the Amex rep that I was chatting with already replaced about 100 cards today.
If you are a current cardholder and want the new one, call Amex or do an online chat.
