What is the Flight Happiness Index (FHI), and why does it matter?

Modern travelers no longer make flight decisions based solely on price and schedule. The expectation today is a reliable, comfortable, and pleasant journey. Flight experience, once a subjective feeling, is now quantifiable through real data. The Flight Happiness Index (FHI) is a scoring system. It helps platforms and travelers see how enjoyable a flight may be.

Flight experience index, flight happiness

FHI uses different factors about aircraft comfort, service quality, and reliability. It gives a score from 0 to 10. This score allows passengers to make more informed choices and enables travel platforms to enhance transparency and user satisfaction.

Key factors that shape FHI

Our FHI model is built upon a wide range of dimensions, categorized into three main data domains:

Data Domain  Key Factors
Amenities DataWi-Fi availability, Entertainment system usability, Power supply (USB/AC), Seat legroom and layout, Aircraft type and cabin configuration, Cabin photos for visual verification
Operational DataAverage delay time, Historical on-time performance, On-time rate prediction based on real-time and historical factors
Service LevelMeal service availability, Passenger review ratings, Overall service satisfaction

A special model that uses machine learning scores each flight. This model changes its scoring based on the traveler's profile, like business or leisure, and the route details.
