I just realized that the requirement of $100 mininum value of the first booking from the referred host to qualify for a $300 reward is obviously not realistic in the part of the world I live in where the average rate is $15 a night. I think there is one in a thousand chance that you get booked for a 7 nights straight to get the $100 minimum value. I think what Airbnb could do is to somehow lower the requirement for receiving the referal reward. The hosts who refer other airbnb members to list their space do not just send an invitation. They have to help the new host to get started and this could mean they spend their valuable time to help Airbnb to get more profit. They should be entitled to some reward if not the $300 at least something. Otherwise why should I care about referring other people to list their space.
