Why us?

Horizon Reservations is one of the most feature-rich and sophisticated systems in the world, and for specific market needs, an efficient process is in place to develop additional functionality. All modules are parameter driven, thus providing access at every point of sale.

While many competing systems require users to submit change orders to manage codeshare partnerships, Horizon Reservations enables users to do it themselves – without delay and setup costs.

Because all components of Horizon® are integrated, Horizon Reservations interoperates with other systems including e-commerce, loyalty and revenue integrity systems for greater functionality than would be delivered by third-party systems. 

Horizon Reservations supports industry standards in line with latest IATA resolutions.
