Here is why you should sign up for every program: it can allow you to keep every program active. So if its been a year since you last traveled lets say, United, spending $5 on the shopping portal and earning points means you'll push back expiration by another 18 months.Here is a list of the popular shopping portals:
- American: AAdvantageEshopping.com
