Delta Skymiles Gold (DL Skymiles Gold) personal AMEX.

Opened 2018, annual fee posted for 2019 at the 13 month point. Called the normal customer service line 800.528.4800, said "thinking about cancelling AMEX Delta Gold card" and got to a rep who quickly offered either a $50 statement credit for $1,000 spend or 7,500 Skymiles after $1,500 spend - both within 3 months.

Skymiles reportedly with 1.2 - 4+ cents per mile if you luckily hit a miles sale or find a good partner transfer so I accepted the miles offer.
