I experienced something similar and Air was no help. I have hosted 100’s, Superhost for years, and contact them once a year max. Lots of wheeling and dealing, but in the end you are on your own.
On a similar note, the security deposit is a mirage. It isn’t even charged to the credit card during the booking and Air will decide how much gets charged. Unless the guest admits it, you are pretty much out of luck as well.
