Airbnb guests in the U.S. can now book their stays without paying up front using the company's new "Reserve Now, Pay Later" policy. Traditionally, Airbnb guests had to pay when booking or through a payment plan, which can lead to headaches when it comes to canceling trips. Guests using "Reserve Now, Pay Later" still must pay before the free cancellation period ends, so that gives hosts time to secure another booking.
