The problem is wingspan; those planes are difficult in the terminal area, the wingspan on a 380 is at the maximum limit for many airports. So unless airports get rebuilt, those large wingspan airplanes are going to be limited compared to the smaller options. It’s a 262 ft wingspan. The C5 Galaxy is 223 ft; a Galaxy would “fit” fine at most airports, but the 380 is cutting it very close. An Antonov has a 290ft wingspan which would make it impossible to use as a normal passenger plane (although they’re very popular in Houston for shipping oilfield equipment.) The 380 is a fun plane, but it’s of limited usefulness beyond passenger load.
