I have 2 cards. The main one I am using is Citibank Air Asia. They have promotions on flights every week, and I have priority booking. Which is good for my company staff who wants to book tickets earlier.

Furthermore there is TGV promotion - weekdays each ticket is only RM 10 (ended already ) and weekend it's buy 1 free 1.

The other card... HLBB. It's a spare card (just sign up so I can get free items), but now I use the card for online purchases (Paypal).
