The Beluga XL is 63.1 m (207 ft 0 in) long, and has a wingspan of 60.3 m (197 ft 10 in), which is around the same of an Airbus A330-200 – what the Beluga XL is based on. The real advantage is the internal space – 2209 m3 (78010 ft3) of it. The internal area of the plane is 46.56 meters long, 7.7 meters wide, not including the sublevel cargo deck for freight, and 7.9 meters high.

The a380 has a fuselage dimension of 8.4m high, its cabin is 6.54m meters wide and 50.68 Metres long. So, lets install some seats – time to do some maths. Looking at the cross-section of the plane, its clear that we can fit in two decks – if not three. These two aisles would be 40 inches combined width, or 1 meter, leaving us 670 cm, or 264 inches to play with.
If each seat it a nice 18 inches wide, or 46 cm, that means we can fill in 14 and a half seats across…This would have to be in a 4 – 3 – 3 – 4 configuration. We might have to take out a seat in the middle to make a third asile, so we will say 14 seats. If the seats have 31 inches of legroom, or 70cm, then we could fit in 55 or so rows, leaving room for door spaces.
This space would have the same twin aisles, and fit 6 business class seats in a 1-2-1 open suite configuration. At 78 inches of legroom, or 200 cm per seat, we could fit 20 or so rows. – because I love bars on planes. This is 4 passengers per row or 80 passengers in total. This gives us a total capacity of around 880 passengers. The A380 by comparison is rated for 538 on the main deck and 330 on the upper./ Found And Explained
