So I was recently approved for the delta gold Amex and the zync. Now I have spend the $500 necessary to get the 30k promo, and now my question is, which card should I use for most of my purchases? I intend on getting a gold in a few months when they run another good promo 50k-75k MR points which I will transfer to delta.
So I have two options. Use the delta and get 1 mile per dollar on most things and 2 mile per dollar on delta. Or I could use the zync for most things and use delta for delta things, then hope delta has a promo to get bonus miles with MR transfer as they did earlier this year whk I get my gold. What do you think?
