Chase Sapphire Reserve
Definition
The premium Chase Ultimate Rewards card. $550 annual fee, $300 travel credit, Priority Pass lounge, 3x on travel/dining.
Why it matters
Best for: travelers who'll use the $300 travel credit (essentially making the fee $250), Priority Pass for 2-3 lounge visits/year. Otherwise CSP at $95 fee is the better starter card.
