Editorial take: Delta SkyMiles Platinum Amex

The companion certificate alone usually covers the annual fee on a single trip. If you fly Delta domestically at least once a year with a partner, this is worth it.

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.
