Frequently Asked Questions
Why multi-card?
No single card maxes every category. Optimal: 3-card combo (e.g. Amex Gold dining, CSP travel, Citi Double 2% everything else) often nets 4-5% effective vs 1.5-2% single card.
Watch out for?
Annual fees. Premium cards ($550-695/yr) only worth it if you maximize travel credits + lounges. Otherwise stick with no-fee 2% flat.
