What was the Boeing 727’s maximum passenger capacity in its 727-200 Advanced version?

The Boeing 727-200 Advanced had a maximum passenger capacity of 189 passengers.

The 727-200 Advanced was an improved version of the stretched 727-200 tri-jet. Boeing added more powerful engines, increased fuel capacity, and upgraded systems, improving the aircraft’s range and operating performance. Its maximum seating figure applied to a high-density single-class configuration rather than every airline interior.

Airlines commonly installed fewer seats to provide more space, galleys, lavatories, and service areas. As a result, published seating figures can differ depending on whether a source gives maximum certified capacity, a typical airline layout, or a particular operator’s configuration.

The 727 was notable for its three rear-mounted engines and T-tail. Its built-in aft airstair allowed boarding without airport jet bridges, a useful feature at smaller airports. The type entered service in 1964 and became one of the most widely used early jet transports.
