This definitely isn’t the most lucrative of deals but United is offering its frequent flyer members 300 miles (600 if you are an elite member or MileagePlus card holder) for joining Opinion Miles Club and completing one survey. As the name suggests, you can earn United miles for completing various surveys on all types of topics.

Since I am a MileagePlus cardmember, I was eligible to earn 600 miles so I decided to try it out to see how arduous the survey was. When I completed the setup for my account, I saw I was eligible for a survey…take was estimated to take 28 minutes! I was about to pass on it but decided to see if it was one of the surveys that I could at least click through quickly. Long story short, I was able to finish it in about 15 minutes (I may or may not have read every question completely) but the miles posted instantly to my account.

Back in the day when I first started out collecting miles, I used to complete any mileage earning survey I could find until I realized it wasn’t a good use of my time. I imagine the time commitment doesn’t make this a feasible endeavor to earn miles constantly for most of you but might be worth it if you got 10-15 minutes with nothing better to do and qualify for the 600 miles. Outside of this one survey, I don’t plan to complete any others.
