Reasons for High Volumes of Boarding Passengers

Why do so many US airports experience so much traffic, anyway? Over the 20th and 21st centuries, the US has seen a large increase in both domestic and international travel. Advancement in technology has made it easy to coordinate travel for millions of passengers every year. Train travel, though once popular, is no longer popular in the United States. Unfortunately, air travel has a concerning effect on climate change.
