Air does have a weight! And it is because of gravity! Note that this is per definition true because weight is only defined in the presence of gravity.
Perhaps you are confused about why the air is up in the atmosphere and not down here on the ground with us?
This has to do with air pressure. You see, materials don't like to be compressed, which is what gravity tries to do. Gravity tries to compress the air to the ground, but faces increased air pressure as it does so.
Basically what happens is that the air particles repulse each other and thus tend to drive them apart. This force increases if you force the particles to be closer to each other.
As gravity tries to pull air down, the air pressure increases which counter balances the pull of gravity. In the end a stable system is formed where the air pressure is highest down near the ground and lowest up in the upper lays of the atmosphere.
The air particles up in the atmosphere do feel gravity, but if they would move down they would feel an increased air pressure which pushes them up again!

How does air apply pressure?
The atmosphere (the air above you) naturally applies air pressure as a result of Earth's gravity. In other words, because it is made of matter it has weight.
Is air pressure a result of gravity?
Yes, it is.
Is a mass or weight determined by gravity?
[ Mass ] is a property of the object, and doesn't depend on the presence or strength of gravity.[ Weight ] is the result of gravity, and changes depending on the local strength of gravity.
How are weight and mass affected by gravity?
Mass is not affected by gravity. Weight is the result of the force of gravity acting on mass.
How heavy something is based on gravity?
Yes. Weight is the result of gravitational attraction. The general relation is: weight = mass x gravity Near the Earth's surface, the weight (in newton) is approximately 9.8 times the mass (in kilogram), since the surface gravity of Earth has that value.
Is weight the result of air pressure exerted on an object?
Mass and Earth's gravity

What gives air its weight?
gravity
Is air pressure a result of gravity?
Yes, it is.
Does gravity give air weight?
Yes.
What is the result of air mass?
the result of air mass/air weight is air pressure.
Is there such thing as weight?
Yes. Weight is the vertical force exerted by a mass as a result of gravity.
Can a object have weight without having mass?
No. Weight is the result of gravity acting on mass.

How are weight and mass affected by gravity?
Mass is not affected by gravity. Weight is the result of the force of gravity acting on mass.
What happens if object weight had no gravity at all?
you will float up in the air
What force on an object is caused by the weight of the air above the object?
gravity
