You can currently earn an easy 250 American Airlines AAdvantage miles by enrolling in e-rewards, via this link, and completing one survey.
The offer is available to residents of the US, Puerto Rico, the US Virgin Islands, Canada, UK and Brazil.
In previous versions of the offer, the bonus has applied even where the survey screens you out after a few questions, although I cannot guarantee this remains the case.
You need to take just one survey to get the miles, although you can then participate in further surveys to earn more miles, should you deem it worth your time.
If you are already a member of e-rewards, you will need to use an alternative email address.
While the benefit of taking surveys through e-rewards to earn points is dubious, given the time you spend on the surveys, these free 250 miles are a straightforward account booster.
250 miles may seem insignificant, but take advantage of these types of offers across your portfolio of loyalty programmes as they arise, and they do add up.
