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.

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.
