At 54 square miles, Denver International Airport is the biggest airport by land area in North America. It’s second in size only to the world’s largest airport, Saudi Arabia’s King Fahd International Airport. Nicknamed DIA, Denver's airport is also double the size of the second-largest airport in the U.S., Dallas-Fort Worth. DIA is home to North America’s longest public-use runway, which stretches over three miles in length. With nonstop service to 215 destinations, DIA sees an average of 61.4 million passengers per year.
Hope this Helps!! :) (can you mark me brainliest?)
