The program lets you earn miles on Continental, Delta, Northwest, or US Airways by viewing internet advertising and then answering questions — questions to prove you watched the ad, and then questions to gauge your interest.

This isn’t an entirely new idea. American Airlines has been awarding miles to people who take surveys through OpinionPlace for some time, and these surveys are 50% market research and 50% advertising.

Is it worth the time, effort, and intrusion into your life by nosy advertisers? Probably not, but the program could help you keep some smaller balances alive if they’re threatened with expiration.

The payoffs aren’t huge: 20 to 30 miles per minute spent watching advertisements, according to this report. (Notably, the company doesn’t specify earnings rates on its own site, which I find fishy.) But you still need to wait until your balance reaches 500 miles before you can transfer points over to an airline. This might take a while, since only 14 advertisers have signed up thus far.

If people sign up, consider dropping me a line describing your experience. How long are the ads? How much are you earning? Etc. The contact button is at the top right of the page.
