I've never heard of a AAA discount with Avis, only Hertz. I thought Hertz was exclusive too.
The United discount is nothing special....usually 5%. The airline discounts (and just about every airline has one) vary depending on location and sometimes the time of year. Occasionally, there are specials which increase the discount %. The only way to ensure you have the best rate is to run every discount number you are aware of for the place/time of your rental.
