You may already hold a card that gives you bonus points on dining, like the Chase Sapphire Preferred (2x) or Chase Sapphire Reserve (3x), but it’s also possible to double-dip by enrolling in an airline’s dining program and paying with your registered card.Enrolling is easy — just create an account with your preferred program, register your card and you’ll earn points and miles when you eat at participating restaurants. Sign-up bonuses are also available and vary by program.Right now, the American Airlines AAdvantage Dining program allows you to earn between one and five miles per dollar spent with a bonus of up to 2,000 AAdvantage miles if you dine three times within the first 30 days of joining. The Delta SkyMiles Dining program also allows you to earn between one and five miles per dollar spent with a bonus of 3,000 SkyMiles if you dine three times within the first 30 days of joining. To round out the three major US carriers, the United MileagePlus Dining program allows you to earn between one and five miles per dollar spent with a bonus of up to 1,000 MileagePlus miles if you spend $25 within the first 30 days of joining.As you may have noticed, these programs are similarly designed, and each of the memberships offer three tiers. In order to reach the top tier and earn five miles per dollar, you’ll have to sign-up to receive emails from the service and have 12 or more qualified transactions within a calendar year. Opting in to emails will get you three miles per dollar and you’ll earn one point per dollar if you don’t add your email. There’s no reason to not earn bonus points and miles when you eat out.To find participating restaurants, just add in your zip code and click search.
