I have noticed that AA's program has some restaurants that UA's program does not. I am currently only enrolled in UA's program. I want to enroll in AA's program to accumulate points for those restaurants not in UA's program, but I want to continue receiving the points in UA's program for common restaurants. Does it work this way?

Anyway enrolled in both programs?

Thanks!

You can enroll in as many programs as you want... only catch is that a credit card can only be enrolled in one program. So, you need a different CC to enroll in program #2.

Doing this also lets you accumulate miles more than once in a month at the same restaurant....
