I'm a medical student who is getting ready to do some traveling for residency interviews. I'm looking at getting a card that I can use to give me rewards for my interview travel, but is still something I can keep and use after interviews are done. The cards I'm considering are the CSP, Barclay Arrival +, and AMEX Everyday Preferred. A little bit about my spending: I spend $2000-2500 each month, the majority of it groceries, dining, gas. I'll be spending quite a bit (for me) on travel over these interview months, but typically I fly domestically a handful of times a year. My wife's family recently moved away, so she's going to be flying more often, so having a card that gives travel rewards is something I'm interested in.

CSP: I like the signup bonus and that I can use UR points for Southwest tickets, but I'm not sure how valuable the card will be after the interview season since I wouldn't be spending very much on travel.

Barclay Arrival +: Again I like the signup bonus, and I like the simplicity of this card and that I get 2x points on all spending, which is great since outside of this interview season most of my spending is on non-travel categories.

AMEX EDP: it seems like this card makes sense for the purchases I usually make (gas, groceries), but I'm not sure the value of the MR points compared to using UR points with CSP.

Any suggestions or advice would be great! Thanks!
