Editorial take: AAdvantage Aviator Business Mastercard

Cleanest AA business card under $100 fee. Free bags for 5 travelers + the $30k companion cert + an easy 65k bonus. Solid for any AA-leaning small business.

Editorial take: United Explorer Card

Solid for United flyers. The free checked bag and 2 United Club passes per year add up, and the 60k bonus is a great starting point for domestic award flights.
