Farel

Farel is a software company that builds an AI-native airline operating system intended to replace legacy Passenger Service Systems (PSS). The platform unifies inventory management, dynamic pricing, reservations, departure control, distribution, payments and customer-facing applications within a single integrated system, operating independently of traditional GDS constraints. It is aimed principally at airlines, including regional carriers.

The company's product, the Farel Airline Operating System, is live with airline customers across four continents and processes over one million passengers annually. According to the company, airlines can be launched on the platform in weeks rather than months. Technical work spans artificial intelligence, airline operations software, revenue management, reservation and departure control systems, payments infrastructure and distribution systems.

Farel is headquartered in San Francisco and is backed by Y Combinator and other Silicon Valley investors. The company describes an engineering culture oriented towards AI-native development and the automation of routine tasks, with a stated focus on modernising regional aviation through software.
