If you chosen to receive your payment via Paypal, make sure you check the minimum payout amount you've set. Sometimes this gets forgotten and noticed that you haven't received the funds yet after a guest check-out that only hasn't reached the minimum amount yet, therefore goes on hold by Airbnb until the payout reaches the minimum amount. We haven't tested bank-to-bank or any other methods yet so not sure if other methods require minimum payout amount.
When do I get paid?

"If you have a minimum payout amount set, your payout won’t be released until that amount is met. If you have multiple listings with check-ins on the same day, any funds going to the same payout method will be deposited as a single payout."
