I wanted to pass along this link to the Delta Gold SkyMiles American Express card. You’ll get 35,000 miles after $750 spend in 3 months, and the $95 annual fee is waived in the first year. Plus you’ll get your first checked bag free.
The previous best offer is for 30,000 miles (plus a $50 account credit) after $500 in spend (one could argue that those are actually similar offers, and you’re just trading off 5,000 miles for $50 in account credit. I guess I could be swayed that way, too. If you’re interested in that deal, here’s that link).
I’ve updated the Best Airline and Hotel Offers page with the new deal.
