Airbnb most likely set up a refund policy a long time ago, and isn't keeping up with the times. The guests that use the refund policy after check in, are well versed on how to get the refund, remember if they cancel before hand, Airbnb's fee is kept by AIRBNB. Guests check in tell airbnb they want their money back, and the host is out, most likely they've already booked somewhere else, and know they need to cancel after checking in. NOT FAIR... hosts have accepted the booking, blocked out the time, set a refund policy, and now are stuck with guests that know how to beat the sytem.. I don't want a guest that doesn't want to stay. If someone books a place, there should be no refunds prior to 60 days of check in... unless the time can be rebooked, however Airbnb won't unlock your calendar if you do cancel them per their request.. so you have to rely on other sites to rebook... I do like the 24-48 hour cancellation after the intial booking for those that can't make it. We don't want guests staying if they don't want to.. and should not be penalized for it, they should buy trip insurance.. maybe that is something Airbnb could sell to make themselves more Money - my two cents..
