For Commonwealth Award Credit card holders, Kaligo is giving 15x bonus points per $1 spend on all accommodation bookings with some having extra bonus attached. I booked recently and found that the prices are very competitive with Bookings.com and Hotels.com and many other site. Kaligo will compare and show you competitive pricing also.
For example booking a 2 night stay at a hotel for $500 will give you 7500 bonus points including the 500 points originally earned by using your CC. SO that 8000 points for a 2 night stay. Which is roughly $40 back in award points. There is also referrals available where you will receive an extra 1000 points for using a referral or referring someone.
Thanks
I have also realized that these can be used for Etihad Guest points as well as a range of other rewards programs, not just comm bank rewards.
