The advent of the Capital One Venture X Rewards Credit Card has people reevaluating their wallet space for premium credit cards. The American Express® Gold Card (see rates & fees) with its high earning potential in various categories has been a consistent keeper in many people’s wallets.

It’s easy to get excited about the new kid on the block and throw out the well-worn card in your wallet.

I’ve been a huge fan of card combinations that can really sweep you off your feet at the ability to rapidly earn tons of points without chasing a bonus. Combos like the Citi Premier® Card (Note from the editor: Citi Premier® Card is no longer available to new applicants) and the Citi® Double Cash Card, or the Chase Sapphire Reserve® and the Chase Freedom Unlimited®.

For the past few years, the Chase Sapphire Reserve® and Chase Freedom Unlimited® has been my absolute go to combo.

With a wallet full of credit cards, it's best practice to commonly assess your credit card portfolio to ensure that the benefits you receive from the cards outweigh the annual fees that you pay. If not, it's time to close that card or cards in most cases.

The American Express® Gold Card, with its high reward rate in certain spending categories, is one of the best rewards cards to hold for dining and travel lovers.

The card’s elevated welcome bonus is enough to book a flight in business class on multiple airlines.
