Etihad is the latest airline to partner with HolidayCheck to offer airline miles in return for reviewing hotels on their website. It seems that, in an attempt to compete with TripAdvisor, HolidayCheck needs to offer generous incentives to get you to review.
You will earn 150 Etihad Guest miles for every hotel review you post on HolidayCheck. You can find full details on the Etihad website here.
As Etihad allows you to cash out your miles for ‘virtual’ Visa cards via PointsPay at 0.4p per mile, you could effectively earn 60p per review by doing this even if you had no interest in the Etihad miles! PointsPay does charges 99 cents per withdrawal transaction though.
Other airlines also let you earn miles via HolidayCheck. These are:
Miles & More (100 miles per review)
airberlin topbonus (150 miles per review)
airBaltic BalticMiles (150 miles per review)
