This is one of the slower and more time-consuming ways to earn air miles & points. If you have the time though, and are happy disclosing your habits and opinions, the points you earn can add up!
All the main US Airlines have a partnership with a survey company. You can also earn miles for non-US airline programs with a few of the survey companies e.g. Air France, Etihad, Iberia,
Below is a list of the main US Airlines and their survey partners.
Alaska offer miles through The Opinion Terminal
Frontier offers miles through e-Miles
Hawaiian offers miles through Opinions Take Flight
JetBlue offers points through Points For Surveys
Spirit has Miles for Thoughts
Virgin America is partnered with e-Rewards
You usually earn a good sign up bonus of a few hundred to a thousand miles / points after taking your first survey. After that, you will often earn less than 100 per survey.
If your chosen airline, partners with several survey sites, you can sign-up to all of them and complete your first survey to earn a quick few thousand points!
The length of the surveys vary greatly, with some taking just a few minutes and others taking an hour. You won’t qualify for every survey available to you, which can be frustrating, as you usually have to spend time answering qualifying questions first. Some of the survey sites will award you a small amount of points for answering the qualifying questions even though you don’t qualify for the survey.
If you don’t complete any surveys for a while, the sites will email you multiple times to entice you back, with increasing point offers. This can be a lucrative strategy, but you do have to put up with the multiple emails…
Personally, I think completing your first survey for the sign-up bonus is worth it. However, the rewards offered for completing future surveys can be small, and the time vs. value relationship isn’t there. Though if I needed just a few hundred miles to top up my account to redeem for a flight, I would spend a few hours completing surveys to do it!
Here’s a link to a great blog post that outlines the pro’s and con’s of each of the survey companies offerings.
