My card arrived today: Lifetime Titanium Elite. I’m assuming this is the one-off status for SPG members with 750 nights/ 10 years ( that discussion was so long ago....).. in any case, it’s metal but lighter than the cards doled out by SPG in 2012. I won’t carry either lest they trigger metal detectors/unwanted scrutiny.
Better late than never; and I guess it’s nice to have....
