Letti, mind if I join here as a noob and kindly ask you to check what the terms and Refer page says for you now? I've been back and forth for hours with AirBnb support right now because I referred someone for a $360 bounty and I only received $300 in the end. They are adamantly claiming that it's been $300 since 26th of March 2018. Because that's what the Terms and Conditions page claims (https://www.airbnb.com/refer/terms_and_conditions)
Meanwhile I found countless articles and mentions of hosts ( including a couple from you, thank you ) about the bounty being $360. I just wanna know if our Terms or Refer pages are showing a different amount (you as a Superhost, me as having lost it). I have recently had to cancel on a booking and lost Superhost status, which would explain the reduction from $360 to $300 (20% as Douglas said) - but considering the eligible booking was done when I was a Superhost, I would be entitled to the full amount.
