The second payment is take before arrival, @Tracy627. Whether you can confirm this with Airbnb is questionable, if you could even bear to make that call. What issues have you had to make you ask the question?
@Gordon0@Tracy627 Airbnb generally hides all guest payment information from hosts. There is however one way you can determine whether a guest's payment is complete: attempt to ask them for money in the resolution center. You will be prevented from sending the request if their payment is incomplete.
