Editorial take: Delta SkyMiles Platinum Business American Express Card

Strong middle-tier Delta card. The annual companion certificate alone covers the $350 fee for any couple flying domestic. Sky Club access at member rate is also better than nothing.

Editorial take: United Quest Business Card

United's mid-premium business. The $200 travel credit + 10k mile rebate after award bookings + 6 club passes routinely justify the $350 fee for any frequent United business traveler.
