Editorial take: Bilt Obsidian
The headline tier of Bilt 2.0, launched February 7, 2026 by Cardless after the Wells Fargo era ended. Strongest for renters who eat out (or buy groceries) and use Lyft. The $100 hotel credit pays back most of the AF if you stay 2+ nights anywhere on the Bilt Travel portal. Pair with the no-fee Blue if you want a no-AF anchor too.
