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.

Editorial take: United Explorer Card

Solid for United flyers. The free checked bag and 2 United Club passes per year add up, and the 50k + 10k AU bonus is a great starting point for domestic award flights. $0 intro annual fee, then $150.
