Real-World Travel Tips to Beat the Clock at DEN

Planning a trip from Denver? Denver International Airport (DEN) is one of the largest airports in the U.S. by land size and among the busiest in passenger traffic. If you're wondering how early to get to the airport, the answer depends on a few key factors—including DEN’s layout, traffic, and security lines.

Here’s how to arrive early, get through security fast, and make your flight with no last-minute stress.

Best Time to Arrive at DEN

• Domestic Flights: Get to the airport 2 hours before takeoff.

• International Flights: Plan to arrive 3 hours ahead.

Even for short domestic trips, DEN’s size and security line wait times mean cutting it close isn’t worth the risk. Early mornings and weekends can be especially crowded, so pad your schedule.

Airport Security Wait Time at DEN

DEN’s main security checkpoint is located in the Jeppesen Terminal, and lines can back up fast during busy periods. While DEN has a secondary (North) checkpoint and TSA PreCheck lanes, it still sees high traffic volumes during peak hours (5 AM–9 AM and 3 PM–7 PM).

Travel tip: Use the MyTSA app or check the FlyDenver website to see real-time updates on airport security wait time before you leave. Signing up for TSA PreCheck or CLEAR can significantly reduce your time in line.

City Airport Travel Tips: Getting to DEN

DEN is located about 25 miles from downtown Denver, and the commute can be longer than expected depending on time of day.

Here are a few city airport travel tips for getting there smoothly:

• Driving? Plan extra time for I-70 and Peña Boulevard traffic, especially in winter or during rush hour.

• Using rideshare? Follow the airport signs to the designated pickup and drop-off zones on Level 5.

• Taking the train? The A Line (RTD) offers a direct 37-minute ride from Denver Union Station to the airport.

Tip: DEN is massive—once inside, you may still need to take a train from the terminal to your gate.
