What is an internet booking engine (IBE)?
An internet booking engine, or IBE, is the software that lets travelers search availability, choose what they want, and pay for it directly online, whether that is a flight, a hotel room, or an event ticket. It is the part of a travel site that actually closes the sale.
Behind a simple search box sits a lot of work: live availability, pricing rules, seat or room selection, and secure payment, all happening in seconds. When it is smooth, the traveler barely notices it. When it stalls, they leave.
For travel businesses it is mission critical, because the booking engine is where browsing turns into revenue.
Sthenos built a digital ticket booking platform for a leading UK airline, and a free proof of concept is a common first step for systems this central.
Related terms: global distribution system (GDS), passenger name record (PNR).
What is the difference between an IBE and a GDS?
An IBE is the customer facing booking tool. A GDS is the wholesale network it often connects to in order to find availability and fares.
