Hello and thank you in advance.

I am planning a trip to China for my family of 3 for next May. I have miles in AmEx MR; however, find that pricing this trip out, it doesn't seem to be a very good cent per mile ratio (at least with Delta). We also use Sapphire Preferred. I am thinking United might be my best bet but would greatly appreciate help!! We generally fly economy to make miles go further; however, this is a long flight.

I have a large current expense ($14000) but to use cc must pay 2.9% fee. 2.9 cents / mile is much more than I have ever paid;; however, am wondering if there might be a use of these on our China trip to make it worthwhile. We have a duplicate expense in January. Help is appreciated
