Thanks for the replies!
Will definitely consider getting another card now!

mia, per your questions:
- domestic 50% (US) as well as international 50% - Southeast Asia/Europe
- most likely economy most of the time, as premium will require more points/miles
- one person

artemis, I'm afraid my credit score (Transunion 680, Equifax 699, FICO 669) won't be enough for this one. What do you think? (It's weird that it's so low, I have 11months history, not a single late payment; probably other loan dragging it down...)

runb4fun,

what cards do you mean? i.e. can I use non-Chase cards as well?
