It depends on the type of airplane. There are small airplanes for only one person and new jumbo-jets that can carry over 750 people in the right configuration. Ultimatly it comes down to wieght. An airplane can only carry as much weight as the wings can produce lift.
They can carry their own weight
In many ways such as how much fuel do I need to carry to fly 300 miles. One of the most important things for a pilot to know is how much weight he has on the airplane and, since fuel is figured in weight instead of gallons on a airplane, he probably better know basic algebra and general mathmatics.
Stand on a scale. Figure out how much you weigh. Then pick up the airplane and stand on the scale. Subtract how much you originally weighed, and that is the weight of the airplane.
Two people at most. The first airplane carried its engine and 1 man.

The amount of weight a person can carry will depend upon the person. The stronger the person is, the more weight that they will be able to carry.
You can measure the weight of an airplane by using the concept of displacement. Float the airplane in water and measure how much water is displaced. The amount of water displaced will be equal to the weight of the airplane.

Let us say that we have an empty airplane that weighs 3400 pounds. It is going to carry 30 passengers, who have an average weight of 180 pounds per passenger, and each passenger is also going to carry an additional 20 pounds of luggage. What will the airplane weigh with all passengers and luggage aboard?
If you need to go a long ways, if you need to go fast, or if you need to carry a lot of weight.
