HolidayCheck.com has partnership with number of airlines. Now, they have a promotions with Etihad for 200 miles per hotel review (usually 150) until July 14, 2014.
You can do up to 10 reviews per month and sometimes they may require you to authenticate that you have actually stayed at the hotel that you just reviewed.
You can access Etihad’s web page for this partnership here.
This is an easy way to earn some Etihad miles if you stay at hotels. I have not heard that people would have had any problems getting the promised miles.
Here are the terms and conditions of this offer:
• Please enter your Etihad Guest Number at the time of writing your review on HolidayCheck.com.
• A qualifying review is one which has passed the validation checks from the HolidayCheck team and that have been posted on the HolidayCheck website.
• Every hotel review on HolidayCheck is thoroughly checked before being released onto the website. It will take around 2 weeks from publishing your hotel review for the Etihad Guest Miles to be credited to your mileage account.
