I recently received the American Express Platinum Card 100,000 membership rewards offer. The yearly cost of the card is a bit expensive. While I understand there are a lot of perks that come with the card I'm trying to determine how the 100,000 point could best be maximized based on my current points. I currently have around 130,000 MileagePlus miles and my wife has about the same. In addition, we have around 100,000 Ultimate rewards points. I know the membership rewards will not transfer into United points, so what would be the most logical use of the membership rewards points?
