For domestic flights, it’s generally advised to arrive at Denver Airport at least 2 hours before your scheduled departure. This allows ample time for check-in, security clearance, and reaching your gate. For international flights, arriving 3 hours early is recommended
Why Early Arrival is Key
Denver International Airport, with over 69 million passengers in 2022, is a hub of activity, especially during peak seasons.
Arriving at least two hours before your flight is advisable to navigate check-ins, security, and any unexpected delays comfortably.
Knowing Security Checkpoint Hours
DIA’s security checkpoints have varying operational hours. The North checkpoint, mainly for TSA PreCheck passengers, operates from 4 a.m. to 7:45 p.m.
The South checkpoint is open 24/7, accommodating TSA PreCheck during the same hours as the North checkpoint. Post 7:45 p.m., PreCheck passengers use standard lanes for expedited screening.
The A-bridge checkpoint typically runs from 4:30 a.m. to 5:45 p.m.
Preparing for Security
Passengers can pass through security up to 24 hours before their flight. Ensure you have your boarding pass and photo ID ready. For overnight travelers, at least one security lane at DEN is open throughout the night.
DIA’s website offers real-time updates on security wait times, flight departures, arrivals, and connections. You can search for your flight by number, city, or airline, helping you stay on top of any changes.
Arriving early at Denver International Airport is essential for a stress-free journey. With its high passenger volume and specific operational hours for security checkpoints, planning is important.
