The 10K cert can be used anywhere, it's just a 10K reduction whenever you redeem miles. Makes a biz class seat from the US to Korea, only 95K. Ever since they raised all the redemption levels, I thought it was impossible to get a flight anytime soon. I spend every single cent on my CC and average about 30K, I made the free upgrade to Starwood gold for spending 30K last year on the Starwood AMEX.

I'm thinking, using the 10k cert, it brings down an economy ticket to 58K miles, so spending $30k gets you a free economy ticket. Ticket is worth $1100 before taxes. So with my fuzzy math, it's at least 3 cents you get back with every dollar spent, almost 4 cents. If you prefer biz class it jacks up the value even more.

I already got the NW card and cancelled it last year before the fee. I just stick with Asiana because keeping Diamond/Star Gold is decently doable.
