The Chase Sapphire Reserve® is a premium travel rewards card for frequent flyers and travelers who want to maximize their spending. I've used it for its no foreign transaction fees and rich miles rewards program. It's known to offer a competitive rewards program vs its closest competitor, the American Express Platinum Card®, for a lower fee. In addition, the Chase Sapphire Reserve® comes with a number of premium perks, such as travel credits, airport lounge access, and primary rental car insurance.
