Airbnb — the travel startup that lets individuals rent out private homes or rooms in private homes to people as an alternative to hotels — has racked up more than 17,000 nights in its Open Homes program, a voluntary effort where Airbnb hosts can offer their houses and rooms free of charge to people in cities going through an emergency such as a hurricane or flood or other critical incident, either because those people have been displaced from their homes or because they have come to an area to help family go are going through a crisis.

Now, the company is piloting a new version of the program to make it even more ubiquitous: Airbnb hosts, and anyone who might be willing to put up people in emergencies, can now register so that they will be available on “standby” lists.
