Airlines flying it
Where this comes from
Every layout above is researched against published cabin plans for the operator that flies it and then checked against live availability. Where a figure is not known it says so rather than being estimated, which is why some pitch cells read "not recorded" instead of carrying a number we would not defend.
The same aircraft type is not the same cabin at two airlines. Seat count, pitch and the number of classes are decisions the operator makes, which is why this page counts layouts separately from airlines and links each one rather than publishing a single plan for the type.
