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: Bilt Blue
The no-fee entry tier of Bilt 2.0, launched February 7, 2026 by Cardless. Flat 1x earn (no bonus categories — those live on Obsidian and Palladium). Best for renters who want the no-fee anchor + full transfer partner access without paying $95+. The 5-transactions-per-cycle minimum from legacy Bilt is gone, and Rent Day still doubles everyday earn on the 1st.
