Yes Reserve 5x with subscription is the best option after Atlas. The problem is it is not worth paying the 5900 subscription freeYES Reserv w/ travel subscription or YES Marquee, last checked it gives 4.5% to 9%. let me know if any updates?
For small purchases, AMEX Gold.. min. 6.5% on 6x1000.
This is for travel mcc, Intermiles has 2 or 3 mcc depends on purchase.. so, check accordingly.
