Editorial take: Delta SkyMiles Reserve Business American Express Card

Premium Delta business. Sky Club + first-class companion cert combined typically cover the fee for couples on a single trip. Stack with personal Delta Reserve only if you really want unlimited Sky Club.

Editorial take: Bilt Mastercard

The only card that earns points on rent with no fees. Pair it with Rent Day on the 1st of each month for bonus earning, then transfer to top partners like Hyatt at 1:1. A must-have for renters.

Common questions

Which card has the bigger sign-up bonus, Delta SkyMiles Reserve Business American Express Card or Bilt Mastercard?
The Delta SkyMiles Reserve Business American Express Card has the bigger bonus — 100,000 miles, worth roughly $1,200, versus No public offer (~$0) on the Bilt Mastercard.
Is the Delta SkyMiles Reserve Business American Express Card's $650 annual fee worth it compared to the Bilt Mastercard?
Premium cards like the Delta SkyMiles Reserve Business American Express Card ($650/yr) earn their fee through credits — travel, dining, lounge access, statement reimbursements. If you'd actively use $650+ of those credits, the math works. The Bilt Mastercard at $0/yr trades some perks for a lower commitment.
Can I have both the Delta SkyMiles Reserve Business American Express Card and Bilt Mastercard?
Yes, since they're from different issuers (American Express and Bilt / Wells Fargo) the application rules don't conflict. Many points enthusiasts hold both — they pair well when one earns flexible bank points and the other earns a different currency.
Should I get the Delta SkyMiles Reserve Business American Express Card or the Bilt Mastercard first?
Get the one whose sign-up bonus you can hit comfortably without overspending. Delta SkyMiles Reserve Business American Express Card: $8,000 spend in 6 months. Bilt Mastercard: $0 in 0 months. Pick the easier minimum spend if you're new to points; pick the larger bonus if you have planned big purchases coming up.
