Hey all, just wanted a quick audit of my plan going forward with regards to miles. To preface, I'm a graduate student living in Boston, so my spending is limited. I travel back and forth between coasts around 3-4 times per year and try to travel internationally either every year or every other year. I also travel on Amtrak 3 times a month between Boston and New York.

So recently, I have been approved for the CSP, the Amex Everyday Preferred, and the Arrival+. My plan was to use the CSP to get 2x points on travel and dining. Then, I planned on using the Amex Everyday Preferred for all of my grocery purchases (3x). Then, the rest of my spending goes on the Arrival+ (2x on all purchases). This includes $1000 MS for rent through Amex Serve.

I also have around 70k in United Miles and 20k in Amtrak miles.

Does anyone forsee any problems with the scheme? I'm thinking of just swallowing the annual fees when they come around because the benefits may outweigh the annual fees. What do you all think?
