This would be a question of ethics or trechery. A hosts or owner has estabished a strict refund policy with air BnB. With less than 7 days notice ( 5) a renter declares a medical emerency staying at another rental location. The guests asks for a change of schedule to a new date with a stating date in the future. If agreed to this would aleeve the responsibility of the payout from AirBnb for cancelation.. After all it is a new booking. Now with the new schedule of arrival the guests does make the 30 day cancelation notice in a timely manner.
This now leaves the guest or renter with no respondsibity to the first rental time or the second rental time requested.
it leaves the host now with two canceled rental times and no payout.
Please advise on the loop hole in policies and ethics
