Credit card usage to max miles

I recently got HSBC revolution and not too happy with the changes, but i guess no choice. i read citi rewards for miles but not too sure.

So saddening to hear about the HSBC changes. Your citipremier miles card is great for earning miles when using it to book flights and hotels but since your main spending are on those mentioned, maybe you can consider the uob priv miles card. It has 1.4mpd on local spend as compared to yours of 1.2 mpd. Not a huge difference but since you'll spend more on local spending so it can accumulate a good amount of difference. If you want to compare other cards you can check out this post, they compared quite a few!
