United Airlines 737-900
Overview
The Boeing 737-900 is a small, older 12-aircraft subfleet, all delivered in 2001. Unlike the more common 737-900ER, the base 737-900 lacks the extended-range bulkhead and winglets. As a small, aging subfleet it largely retains its original cabin while United focuses the Signature Interior on newer and larger 737s.
