DENVER — Denver International Airport is currently experiencing the busiest summer season in its history.

In May, new routes began to Mobile, Burlington, Green Bay, and Frankfurt, Germany.

This summer, DIA encourages passengers to arrive at least two-hours before their flight and take advantage of free services like free bag check and events at the airport's outdoor plaza.
