Gold card gets you 1 free checked bag, 15% bonus when booking with miles, and 2x SM per dollar spent on Delta. Looks like the current SUB is actually 65K SM, instead of 40K.Gold, no annual fee first year.
If you fly Delta at all, you might look at the Platinum. AF goes up from $150 to $350, but you get:
- SUB: 80K SM
- Companion cert good for travel in all 50 states, Caribbean, Central America (this alone pays the AF, and then some - this pays for my Reserve card AF)
- 3x SM per dollar spent on Delta
- MQD head start: 2,500 MQD (for Medallion status - this is halfway to Silver)
- MQD boost: 1 MQD per $20 spent on the card
- $10/month ride share credit
- $10/month Resy credit
- $150 Delta stays credit (I would never use this, personally)
