Prior to this past week, I would have told you that AirBNB would make the payment on Sat 5 Oct (ie. one day after check in) and, because that falls on a weekend, you would receive it on the next business day (Mon 7 Oct).
However, the situation is now very unclear for UK hosts. Over the past few weeks, AirBNB has moved to a payment schedule that is much longer. UK hosts used to receive payment the same day AirBNB made the payment (unless it fell over a weekend). However, now hosts are reporting that payment is taking 4 or 5 business days.
There was no notification from AIrBNB to UK hosts regarding this change. So, it's anyone's guess as to when your payment might arrive. You might get it by next Friday (Oct 11). Fingers crossed.
