Expedia (through Vrbo) and Booking.com are both major OTAs but attract different audiences and charge different fees. Expedia/Vrbo charges 8% commission in the US and Canada and focuses on family and group bookings of whole-home properties. Booking.com charges around 15% but reaches a much larger global audience, particularly in Europe, and attracts both leisure and business travellers. Most professional hosts list on both platforms.
