Use of article: "by the air" or "by air"? [closed]
I like to travel by the air.
I like to travel by air.
I think the first one is correct because no human can travel in air (general meaning of 2nd one). When "the" is used with air it means by travelling by some "means" but the correct answer is the 2nd one. Why is that?
In this case, by air is actually an idiom, meaning "by flying in airplanes", so the correct usage is without "the."
