If you are fan of free (or almost free) travel, you may like the opportunity to collect extra miles for United Airlines, answering surveys. It may give some boost to your miles accumulation effort and prevent your unused miles from expiration. As per United Airlines guidelines, your miles will expire 18 months from the last posted activity.
So, you may earn 300 award miles when you join Opinion Miles Club and complete your first survey. Plus, you may earn additional award miles for other surveys you complete.
Currently, there is a special offer for all MileagePlus credit cardmembers and Premier members as they may benefit from double award - 600 miles when they join Opinion Miles Club and complete their first survey.
The sign-up process looks easy enough, until you’re identified as a “professional.” That’s when an extra round of questions is presented in and the process takes a bit longer. You will have to fill out a profile in order to get matched up with future earning opportunities.
