Aircraft made transport systems easier as its the fastest way of traveling with high passenger carrying capacity.
Nowadays, with bigger aircraft size, it can transport more passengers and cargo.
So today, we will have a look at jumbo jets, whose size is so big that you may stare at them, wondering, “Does this even fly?”
We will not include US military cargo planes or the biggest plane in the world, Antonov An-225 Mriya, as it’s a transport aircraft.
The Antonov An‑225 was once the biggest vehicle by overall size, a title now held by other colossal machines.
Also, it was destroyed by Russian forces during the Battle of Antonov Airport in late February 2022, during the opening days of the full-scale invasion of Ukraine
In this post, we will only consider passenger airplanes with huge carrying capacity and maximum takeoff weight (MTOW).
Such giants naturally operate from the world’s biggest airports, which have runways long enough to handle them.
According to the maximum size, these are the top 10 biggest passenger planes in the world:
