United just sent me an email about new partnership that they have launched with Opinion Miles Club. You can earn 600 miles for signing up & completing one survey. You can access this offer here.
Seems that this service requires quite a bit of information about you to match the surveys, so you may or may not be comfortable with it.
This would be, however, a perfect way to extend the validity of ones United miles by 18 months.
This should be easy 600 miles for sharing some of your personal information and completing a survey.
I often receive emails from LoyaltyLobby readers asking about ways to extend the validity of their own or family member’s miles. I usually suggest buying something via online mall or doing a survey or two.
