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: Capital One Spark Miles for Business

The strongest catch-all 2x business card with transferable points. The annual fee is waived first year; the Capital One transfer chart includes Aeroplan, Flying Blue, Turkish, and Virgin Atlantic — enough to make 2x meaningful.
