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: Marriott Bonvoy Boundless

One of our favorite keeper cards. The free night award on every card anniversary easily exceeds the $95 fee, and the 15 elite qualifying nights help you reach Marriott status faster.
