@Rob121 Your message has not reached the Air BNB staff that can address your question about why an extra guest fee was not added. You have reached a forum of hosts like yourself who don't have access to your account but can often help explain some of Air BNB rules. When you received the reservation confirmation, did it show a deduction of the Air BNB fee? Did it show that the guest actually requested for 5 people or was it for 4 people? Sometimes guests make a mistake about the number of guests. If the information is not on your confirmation, contact Air BNB. If you need help with doing that, see the community guide on this site for the various ways you can contact Air BNB.
