Get 30,000 bonus miles when you sign up for the Gold Delta Skymiles Credit Card from American Express and spend $1,000 in the first three months from account opening. You'll also get Delta perks and savings like priority boarding, a free checked bag, and a $50 statement credit when you book a Delta flight with your card during the first 3 months. You also get one mile per dollar spent, or 2 miles on qualifying Delta flights and Delta Vacation packages. Plus, there's no annual fee for the first year. If you keep the card after year one, a $95 annual fee applies for each additional year, but saving the cost of checked baggage fees more than makes up for it. Terms and limitations apply.
