Check the thread in post mentioned earlier in this thread, but below is my thinking on this whole thing.
I set mine up to get miles on NWA. Got to 495 points by the end of first Q so have to wait til June for mine to post. Dont know if anyone with NWA got their miles yet but it seems legit after all because others said the 500 cam to them.
I personally do not like to do anything with these types of sites except get the 5 points. Like with MyPoints, I rarely would do any of the activities and be teased by the 20 or 50 or even 100 point promisses because of two things:
1) now you've signed up for something and this turns into more SPAM. Oh ok it's some non business email address you are using, but still, it's something else to deal with. Those little buggers add up and I have enough of them already, don't you? Don't tell me you don't. I don't believe you if you do. (It's like when people claim they have only one password for every account they own online. NOT possible. That's something I don't believe either!)
2) you need to rely on and wait for the points from some obscure 3rd party partner and it's so little it's hardly worth chasing, but it still gets me miffed when I did sign up for X to get say 50 points and nothing comes of it. With Mypoints, I am often searching for the fax or phone number and have to keep the same sort of printed records that I would if I were missing say 5,000 miles from some airline promo I am waiting for. You need to pick you battles. I am learning more about this every day.
Nevertheless, these emile 5-point offers have been coming thru and they do credit the minute you do the tiny 3 question button survey that they give you with whatever ad or service they are talking about. You can get emails that tell you there are offers in your account, or you can log in on your own and often times they will be there without notice. I always say "yes I am interested in seeing ads about this product or service in emiles again" even if I am not. It IS worth 5points after all for me and for you!
I got to pass 500 (am at like 530 now) just into April and so I will wait til June. May not deal with this one too much but it is a good way to keep an airline account alive and hey, if it's no real work or stress, then it's worth it to do it.
So that's my logic. Good luck!
