Many people like to travel(旅游）by plane, because it is fast. But I don' t like it because an airport(机场)is usually far from the city. You have to get there early and wait for hours for the plane to take off and it is often late. You can’t open the windows. You can’t choose the food. Planes are fast, but they still take hours to go out of the airport and into the city.
I like traveling by train. I think trains are safe. Railway stations are usually in cities. When you are late for a train, you can catch another one. You can walk around in the train and open the windows. You can see many interesting things on your way. I know it takes a little more time.
