Hi Guys,
I am an expat in UAE. I now use ENBD Marriott Bonvoy and convert Bonvoy points to Skywards points. I earned about 500K Skywards miles last year and used to buy business/first class tickets. It works well but I want to maximize my Skywards earnings because I use my credit card very much.

I checked several top tier credit cards and it looks like Emirates Islamic Skywards Black and ADIB Skywards World Elite are the good ones. I spend approximately 50K AED + $15K + €5K monthly. My AED transactions are local and the rest of them is international transactions. My spendings are primarily about travel and shopping. Which card is better for my situation to earn maximum miles? Thank you.
