I'm looking to add a new card soon and I'm interested in travel rewards with high point value. I have 750+ credit and looking for $5,000 or less min spend. I currently have Capital One Venture, SPG and Serve. I don't have a particular trip in mind - but I'd like to travel somewhere in Asia or SA in the next 6 months.

I'd likely gear these points towards airline travel. Since I do most of my traveling out of ATL, I'm wondering if there is any advantage to getting a delta skymiles card - but I hear that the point value is pretty weak. On the other hand, I can use the Serve to hit high minimums if the deal is right.

Or is something like CSP the best card to get? I can see the flexibility being advantageous because I wouldnt be confined to Delta and the card generally gets high marks.

Is there something I'm overlooking? General advice? Thanks!
