How we verify our seat data
Every seat map is checked against the airline's own published layout before it goes live. Here is exactly how.
What every seat map carries
The label, the reviewer and the date sit on every map page, so you never have to take our word for it.

Our verification process
Five steps, in order, before a configuration reaches the catalog.
- 01
Source it
Every configuration starts from the airline's own published cabin layout, with independent aviation databases or verified passenger reports used to cross-check.
- 02
Log the source
Each entry records where the data came from, the date, and who entered it, so every seat map can be traced back to what it was built from.
- 03
Check the range
Before publishing, the total seat count is checked against the expected range for that aircraft type. Outside that range, it is held for review before it goes live.
- 04
Human review
A second team member confirms the entry against its source before it is published.
- 05
Re-verify on a schedule
Published seat maps are re-checked periodically, not just once, since airlines retrofit cabins over time.
What our confidence labels mean
Every seat map carries a label showing how it was checked, not just when. A map only earns "Cross referenced" when both conditions are met, not one or the other.
2 or more independent sources agree, and a second team member has confirmed it. Repeated entries from the same source count once, not twice.
The default until both conditions above are met: one source on file, missing a second confirmation, or not yet independently reviewed.
What we add beyond the raw layout
An airline diagram shows you where the seats are. On its own, it does not tell you which ones are worth picking. After a configuration is verified, we add:
Legroom and recline
Measured, not estimated. Compare across airlines with our legroom calculator.
Legroom calculatorWindow alignment
Some window seats do not line up with an actual window. We flag which ones.
Galley and lavatory proximity
Seats near these tend to be noisier and see more foot traffic.
Quiet zones and known issues
Anything specific to that aircraft's layout worth knowing before you pick.
All of this feeds directly into every best-seats guide and into our seat tools' recommendations. See the seat glossary for these terms explained in full.
Who reviews our data
Alex Westridge
Seat data on SeatInfo is reviewed by Alex Westridge before it goes live. Every configuration is checked against the airline's own specs before publishing.
Where our coverage is strongest
We do not cover every airline and aircraft equally well yet, and we would rather say so than pretend otherwise. Our coverage is deepest where our source documentation is strongest, and we are expanding from there, rather than publishing thin, unverified data everywhere at once. If you do not see your airline yet, it is likely next, not skipped.

Two different things, two different paths. Both go to a real person.
Found a mistake on an existing seat map?
Tell us which aircraft and what looks wrong. We track reports and fix the most-flagged maps first, then update the verification date once confirmed.
Do not see your airline or aircraft yet?
Let us know which one, and we will add it to our list. Check what we cover first.
Verification, answered
What the labels mean and what to do when something looks off.
Cross referenced means the configuration was checked against 2 or more independent sources that agreed. Single source means we currently have one source on file.

Every map in the catalog carries its source label and the date a person last checked it.
