Which airlines fly the 737-900?

We've documented 3 airlines operating the 737-900, each with its own generated seat map below — the cabin you get depends entirely on which airline and which specific configuration they fly.

It varies by airline — from 30in to 31.5in among the operators we've measured. See the comparison table below for the exact figure per airline.

Does the cabin layout on the 737-900 differ by airline?

Who makes the 737-900, and what family is it part of?

Boeing builds the 737-900, part of the 737 family — a 3530mm-wide fuselage that every operator's cabin layout has to fit within.
