OTA

Third-party booking platforms like Booking.com, Expedia, and Airbnb that resell hotel rooms in exchange for a commission.

Online travel agencies dominate hotel distribution in Europe. Booking.com alone accounts for the majority of independent hotel reservations in many markets. OTAs charge commissions of 15–25% per booking and impose strict rate-parity requirements. Most hotelier debates about software eventually return to the question of how to reduce OTA dependency through direct bookings.
