Editorial take: Blue Business Plus from Amex

The silent workhorse of the Amex MR ecosystem. 2x on everything up to $50k/year with no annual fee. Pair it with the Platinum or Gold to unlock transfers, and you have a powerful everyday earner.

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.
