Northwest 747-100/200 Regal Imperial layout
Northwest's mid-1980s long-haul cabin: 18 First Class sleeper seats, 48 Executive Class seats and 334 economy seats, with Executive Class on the upper deck.
Map note: Executive Class was split between a private upper-deck cabin and an eight-across main-deck section. The seat map reproduces a Northwest seat chart; the class placement is confirmed by the airline's April 1986 Regal Imperial Service brochure.
