Enroll in MyPoints here and get 750 Free United miles after thirty-day period of Free membership. MyPoint is a shopping portal that allows you to earn points on the things you buy , plus checking targeted e-mail sent to your mailbox, taking online surveys , playing games, etc.
Bonus miles will post 6-8 weeks after 30 days of MyPoints membership.
You could then exchange all these points across many different hotel and airlines . I don’t use MyPoints for shopping at all, as I would rather shop directly through Airline shopping malls . But nonetheless, I will sign up for Free miles as well as the associated junk e-mail! which is a lot so I advise you to create a free email account at yahoo, gmail or hotmail to avoid the junk cluttering your primary email box.
For those who have signed up earlier for a MyPoints offer , you will NOT get the bonus a 2nd time , simply because MyPoints is pretty good about awarding the bonus only one time.
After Bonus miles are posted into your account, you can unsubscribe from all emails to stop getting the Spam. You can do that by logging into your account and at the bottom right of that page you will see the option to Manage Your Account. Select Manage Email Subscriptions.
And then Unsubscribe from all. Don’t forget to save your settings after Unsubscribing.
