The mode of reservation tells us HOW the reservation has reached the hotel. For example, a reservation request may reach the hotel through a written mode such as – letter, fax, telex or e- mail or through a verbal mode like telephone or in person.

In the hospitality landscape of 2026, reservation methods are categorized into Direct, Indirect, and Automated channels. Direct Reservations are made through the hotel's own website or mobile app, often rewarded with "Member Only" rates and loyalty points. Indirect Reservations occur through Online Travel Agencies (OTAs) like Expedia or Booking.com, or through traditional travel agents who utilize Global Distribution Systems (GDS) to secure bulk inventory. Automated Reservations are the 2026 trend, where AI-driven concierge bots handle bookings via WhatsApp or voice-activated home assistants like Alexa. Historically, reservations were also made via "Central Reservation Systems" (CRS) for large chains. Each method has a distinct financial impact: direct bookings save the property a 15–20% commission fee, while OTA bookings provide the guest with broader comparison tools. In 2026, "Parametric Reservations" have also emerged, where a room is automatically held based on a traveler's flight arrival data to ensure a "seamless check-in" the moment they land.
