I am LTP, have both the 'old' black background card and the Boundless.
As far as I can tell, the old card is 3X for Marriott and 1X for everything else, no other tangible benefits that I don't get with other cards, plus a $45 annual fee. I thought this card used to include a free FNC, but that does not appear to be the case anymore.
Any reason to maintain this card? I don't use it and $45 is $45.
