@Robin12 Ouch! Airbnb releases the funds to your bank approximately 24 hours after the time you have set for check in. Depending on the account type you set for receiving payouts it could 3 -4 days to actually be deposit, depending on weekends, holidays and the like. Certainly your payout for this reservation should be in your account by now.
Contact Airbnb and the finanacial institution handling your payouts to see where things went astray.
