Japan Airlines operates 5 different Boeing 787 configurations with various seat pitches. JAL's 2-4-2 layout provides a competitive edge over other carriers offering cramped 3-3-3 seating.

The data reveals that the carrier's Boeing 787-9 Dreamliners can seat up to 294 passengers in a three-class cabin configuration: 26 in business class, 21 in premium economy, and 247 in economy class.
