Didn't really work. Waiting for my flight to be booked for now over 5 days. The support is only telling, that it will be done in the future soon...
And one note on the side: It's not based on real flight bookings, it's based on leveraging miles (bonus-points which you can collect by flying with an airline) to make it cheaper.
All in all a good idea, but execution seams not that good so far.
