So by "the biggest" the video is actually about the length of the aircraft, then yes, the 777-9 is the longest. But by calling this video "the largest" it should be referred to the weight of the aircraft. That's a very well known fact within aviation. So the Airbus A380 would be number 1, and number 2 would be the 747-8, and so on and so on, you get my point.

He said the A350-900 (passenger capacity indicated in the video:440)has a higher passenger capacity then the A350-1000(passenger capacity indicated in the video: 410). The official Airbus website says, that the A350-900 has a passenger capacity from 300 to 350 passengers and the A350-1000 has a passenger capacity from 350 to 410 passengers. Bro what sources do you use??

TANX,,,but all passenger capacity you told us are the MAXIMUM ,but for last plane 426 is the capacity of 777-9 for normal 2 class format,,,its maximum capacity is about 500-550 passengers in 1 economy class...for example all A380 capacity in the world is around 550 passengers,but 1 company did 840 in 1 economy class...because having 1st class or business class bring more profit with less crowd problem...
