(EDIT, March 2015: The direct application link has now been removed and it appears you need to wait until Iberia emails you with an invitation.)
I have written about e-rewards before as it is a long established partner of British Airways and avios.com. It is a market research company which awards you points in its own loyalty scheme for completing surveys online which can then be converted into airline miles.
In general, I am not a fan. The miles earned for every hour of your time you put into the surveys is not great in my view. Even worse, the surveys often throw you out after a few minutes if they decide that you are wrong age / sex / occupation / race they are after, and you only receive a small percentage of the reward you were promised.
When it comes to the sign-up bonuses, it is a different story.
Both British Airways and avios.com have been offering 750 Avios for joining e-rewards and completing just one survey. That is a great deal. You can join via avios.com here. In theory you can join via British Airways here but the link has been faulty for a couple of months.
You can join both programmes as long as you use a different email address for each.
There is now an ‘open to all’ e-rewards sign-up link for Iberia Plus available.
As usual, you will receive 750 Avios in an Iberia Plus account for completing your first survey. Remember to use a different email address from any you have used before.
If you don’t already have an Iberia Plus account, you can open one at iberia.com. Iberia Plus has an obscure rule which stops you using ‘Combine My Avios’ to move your points into BA or avios.com until your account is 90 days old. Even if e-rewards awards your points promptly, you won’t be able to move them to British Airways Executive Club until March.
