Sometimes you just need a few frequent flyer miles, to reach an award threshold or to keep your accumulated miles from expiring.

Then, within three months of enrolling, take one of the proffered surveys. You’ll earn 250 miles for enrolling and taking the first survey, plus the miles awarded for that first survey.

Longer surveys award more miles; shorter surveys award fewer. And in both cases, the numbers aren’t big. But sometimes, a handful of miles are just what’s needed. In that case, a bit of opining might just be the quickest, easiest way to get them.
