I just received an email for the Alaska Airlines Visa Signature card. It is 25k miles on signup, plus 25k miles after spending $1000 in 3 months. While on principle I usually don't signup for annual fee credit cards (this one has a $75 annual fee), the combination of the $50k bonus miles plus the annual companion fare seems too good to pass up. Does anyone have experience downgrading this card after a year to get rid of the annual fee? Or perhaps the companion fare is worth the fee on an ongoing basis. If you use the companion fare, it is certainly worth more than $75.
