Citi Platinum Select/AAdvantage Card. Experts recommend this card if you frequently fly American Airlines. Currently, the card is offering 50,000 American Airlines AAdvantage miles if you spend $3,000 within the first four months—enough for two domestic round-trip flights. Citi will also reimburse 10 percent of the miles you redeem each year up to 10,000 miles. "That right there pays for the $95 annual fee," Kelly says. The annual fee is also waived the first year.
Gold Delta SkyMiles Credit Card. This is one of the best cards for an individual airline, says Detweiler. You and up to eight people can check your first bag for free on any Delta flight. "That alone can save you the price of your $95 annual fee, which is waived the first year," Detweiler says. You can also earn 30,000 bonus miles if you spend just $500 within the first three months.
Each rewards card offers incentives for different business expenses, so be sure to pick the best match for your company.
