The Delta SkyMiles® Blue American Express Card can save you money and help you earn miles if you frequently fly with Delta. If you want the freedom to earn rewards and travel with any airline, the Capital One Venture Rewards Credit Card could suit you. This card offers 2x miles per dollar spent and enjoy a one-time bonus of 75,000 miles once you spend $4,000 on purchases within 3 months from account opening, equal to $750 in travel.
If you're in the market for another strong, general travel card, consider the Chase Sapphire Preferred. It's a little more complicated if you want to get the most out of it and asks for a $95 annual fee, but it's very versatile and rewarding. It earns 5x Chase Ultimate Reward points per dollar for travel, 3x Ultimate Reward points for dining, select streaming services and online grocery purchases.
If rewards are redeemed for travel through Chase Ultimate Rewards, cardholders get a 25% bonus, bumping the value of points from 1 cent to 1.25. But, there's a 1:1 transfer rate to Chase's airline partners, where cardholders could find an even greater value.
