The Tupolev Tu-204 is a twin-engined medium-range narrow-body jet airliner capable of carrying 210 passengers, designed by Tupolev and produced by Aviastar-SP and Kazan Aircraft Production Association. First introduced in 1989, it was intended to be broadly equivalent to the Boeing 757, with slightly lower range and payload, and had competitive performance and fuel efficiency in its class. It was developed for Aeroflot as a replacement for the medium-range Tupolev Tu-154 trijet. The latest version, with significant upgrades and improvements, is the Tu-204SM, which made its maiden flight on 29 December 2010. In April 2022, United Aircraft Corporation (UAC) announced plans to assemble 70 Tu-214s by 2030.

A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than 4 metres (13 ft) in width.
In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than 5 metres (16 ft), allowing at least seven-abreast seating and often more travel classes.
