How accurate is your data?

Seat dimensions are sourced from published manufacturer specifications and airline configuration data. We update our database as airlines reconfigure their cabins.

Do you cover premium economy or business class?

Currently we focus on standard Economy Class only — that's where the biggest comfort differences exist between airlines.

How is the comfort rating calculated?

Our rating combines seat pitch, seat width, and recline into a single score out of 5. Each factor is weighted by its impact on long-haul comfort. See our Methodology page for the full formula.

Is AirAtlascomfort free to use?

Yes, completely free. No sign-ups, no paywalls. We believe everyone deserves to know what they're getting before they book.
