Thank you for posting this. I just applied online and received instant approval. Since our health care insurance alone is $800/month, charging $4K in 3 months should be pretty easy.
The $450 annual fee is hard to swallow, but the travel credits will come in handy for two upcoming trips. What really drove the decisions, however, was the 125,000 Chase Freedom & Ink points that I've saved up. The way I'm understanding it, if I transfer those points over to the Chase Sapphire Reserve account, they'll be worth 1.5x the amount when I redeem them for travel. Yah!!!
