The Boeing 747-400 Large Cargo Freighter is a wide-body cargo aircraft modified extensively from the Boeing 747-400 airliner. The outsized aircraft, known as the Dreamlifter, was designed to transport Boeing 787 Dreamliner parts between Italy, Japan, and the U.S.So why don’t we put some passengers in it? After all, with more space than even the proposed Boeing 747X, this plane would change the landscape of aviation and commercial freight forever – let us dive into it.

The Boeing 747 dream lifter nearly has all the same specifications as the 747-400, slightly longer by 1 meter, or 3 or so feet. It is taller, however, at 21.54 meters or 70 feet and 8 inches and is wider at 8.38 meters, 27 feet and 6 inches, approx 2 meters more than the 747-400.If the upper level has a width of 838 cm, and the average seat is 17 inches across or 43 cm, then we can fit a total of 16 seats across, factoring in twin aisles.

Now that’s quite complicated as it would mean a configuration of 5 – 6 – 5 which is unrealistic, but we could fit in a third row in exchange for an extra seat and end up with 4 – 4 – 4 – 4. Brutal, but not outrageous. A more realistic option would be a 3 – 4 – 4 – 3, giving room for the bulkhead. At 45 rows of passengers on the upper deck, this would be 14 x 45 or 630 passengers.


But what about the lower deck? The lower level has the same width as a Boeing 747, and thus, we can assume the same configuration of 3-4-3 across with 17 inches of width. Now for the rows, the plane likewise has a similar lower level and we can assume around 45 rows, giving us 450 passengers on the lower deck if all economy. In combination, this is just over a thousand passengers, or 1070 souls.
