Boeing 787 Cabin

The Boeing 787 8 seats 240 in a two-class domestic configuration, with a 46-in (116.8 cm) pitch for first class and a 34-in (86.4 cm) pitch for coach(economy) class.

296 passengers can be seated in a high-density 3+2+3 coach(economy) arrangement with a 36-in (91.4 cm) Business and 32-in (81.3 cm) Coach(economy) pitch.

Up to 234 passengers may be seated in a three-class setup that uses 61-in (154.9 cm) pitch in First Class (2+2+2 or 1+2+1), 39-in (99 cm) pitch for Business (2+3+2 or 2+2+2) and 32-in (81.3 cm) for Coach (2+4+2). Cabin interior width is approximately 18 feet (547 cm) at armrest, and was increased by 1 inch (2.5 cm) over what was originally planned.

787 Cabin Width

The Boeing 787 Dreamliner interior cabin width is a full 15 in (38 cm) greater than that of the Airbus A330 and A340, but 5 in (13 cm) narrower than the Airbus A350 800 XWB. For economy class in 2+4+2 or 3+2+3 arrangements, seat-bottom widths will be 18.5 in (47cm), comparable to that found on the Boeing 777. For 3+3+3 seating, the seat widths would be approximately 17.2 in (43.7 cm), the same as those found on the Boeing 737. The vast majority of airlines are expected to select the 3+3+3 configuration on the Dreamliner.

Boeing 787 Windows

The cabin windows are larger than others currently on in-service civil air transport (27 cm by 47 cm), with a higher eye level, so passengers can see the horizon, with Electrochromism-based auto-dimming to reduce cabin glare and maintain transparency. The Dreamliner cabin is equipped with LED lighting and electronic window shades. These are to be supplied by PPG. Light-emitting diode (LED) cabin lighting (three colour) will be used instead of fluorescent tubes, allowing the aircraft to be entirely ‘bulbless’ and have 128 colour combinations.

Flight Control Systems

A version of Ethernet—Avionics Full-Duplex Switched Ethernet (AFDX) / ARINC 664—will be used to transmit data between the flight deck and aircraft systems. The flight deck features LCD multi-function displays, all of which will use an industry standard GUI widget toolkit (Cockpit Display System Interfaces to User Systems / ARINC 661). The Lockheed Martin Orion spacecraft will use a glass cockpit derived from Rockwell Collins’ 787 flight deck.  Like other Boeing airliners, the 787 Dreamliners will use a yoke instead of a side-stick as used in Airbus aircraft.

Breath Easy on the 787

The internal pressure will be increased to the equivalent of 6000 feet (1800m) altitude instead of the 8000 feet (2400m) on conventional aircraft. According to Boeing, in a joint study with Oklahoma State University, this will significantly improve passenger comfort. Higher humidity in the passenger cabin is possible because of the use of composites (which do not corrode). Cabin air is provided by electrically driven compressors using no engine bleed air. An advanced cabin air-conditioning system provides better air quality: Ozone is removed from outside air; HEPA filters remove bacteria, viruses and fungi; and a gaseous filtration system removes odors, irritants and gaseous contaminants.

Boeing 787s larger windows give a better outside view to all passengers. In addition window can transition from full visibility to opaque so no blinds are required. More weight saving.

Boeings new look interior gives a feeling of space with LED lighting adding to that effect as well as sweeping curves.

  1. Flew for the first time from Chicago to London in August, 2019. Very comfortable flight, and even at the economy seat, enough space for the passenger.

  2. Seat width comparable to 737: Ugh! I have 4 8-hour flights ahead of me in this and already regret it not being a 777. IMO the 777 was the best for transatlantic travel in coach, even better than the A350.

    1. Hi Steve,

      wow, it is hard for us down in this part of the world to imagine people are still travelling on long haul flights. Travelling at all even. So what makes the 777 better than the A350?

      Cheers Peter
