The a380 can carry up to approximately 853 people
In a small airplane up to 3 passengers can be accommodated. This depends on the size of the plane. In small private jets up to 15 passengers can be accommodated.
The largest helicopters don't carry people. The largest passenger carriers I can think of are the Russian Mi-26, which can carry about 90 passengers.
Helicopters carry from 1 - 90 passengers
Over here you can carry as many passengers as the car is designed to carry.
120 passengers
Depends on the aircraft. Some planes such as the 787 and 320 can carry up too 250 passengers, While an Embraer 145 can only hold about 25-45.
A small airplane can fit upto 4 passengers.
In Utah, a car can legally carry as many passengers as there are factory-installed seatbelts.
how many passengers can the largest helicopter hold
The original Wright Flyer held no passengers, only the pilot.
That would depend upon the size of the helicopter, wouldn't it. I have seen tiny one-man choppers, and huge ones. The Russian Mig 6 could carry 90 passengers, but the current largest passenger helicopter, the Sikorsky S-92, can carry 19 passengers.
The largest trains carry about 1000 passengers. So, theoretically if the train stopped running and all the passengers had to drive themselves by car, the answer is up to 1000 cars.
