Definitely a great Miles card. I wouldn't say I am a HUGE spender, but after just 6 months, I am almost entitled to a two way ticket to Shanghai. That's pretty decent considering I used it just on a regular basis with one other credit card.
What could be better is that UOB doesn't allow any way for us to see how we are earning our points, where we got bonus points, etc. IT would help if we could see that, cos then I would adjust my behaviour to maximise my points earnings. Also, there was no way to know if I was eligible to the bonus miles for signing up. I called in and even they couldn't answer! This ambiguity is uncalled for, and not a very good business practice.
You gain lots of points on travel sites like Agoda, but they need you to go through UOB's dedicated Agoda link, which I then realised shows different pricing to Agoda's normal site (it was higher on UOB's site)..... so in that sense, that' not really earning points....it's spending more that is converted to points. I think this is misleading.
Otherwise, the card itself is great.
