Terminal and Check-In Details
Terminal assignment
Southwest operates from the Main Terminal (also called the Jeppesen Terminal) at Denver International Airport. The Main Terminal handles all domestic and international commercial passenger services and is where you complete check-in and security. Within the terminal, Southwest uses specific counters and kiosks for its passengers. Note that DEN sometimes uses a separate North Satellite for other airlines, but Southwest does not use the satellite; you will stay in the Main Terminal.
Baggage check and drop
- Bag fees: Southwest includes at least two checked bags free for most fares; bags within size and weight limits are generally unrestricted.
- Bag drop locations: Southwest bag counters and self-service kiosks are located in the Main Terminal. Some travelers also use automated bag drops if available at that time of day.
- Size and weight limits: Checked bags are generally limited to 62 linear inches and 50 pounds; oversized or overweight bags may incur fees.
Security and screening
After check-in, proceed through security in the Main Terminal. Arrive with ample time, especially during peak travel periods. Wear items that are easy to remove (belts, jackets, shoes) and place electronics and liquids in your carry-on bins for faster screening. Note that DEN participates in TSA programs such as CLEAR where eligible, which can expedite the security line.
Boarding and Getting to the Gate
Southwest uses a numbered boarding policy, so you board based on your boarding position rather than assigned seats. Gates are located within the Main Terminal and are typically within reasonable walking distance. Monitor the flight information displays for gate changes and estimated board times. If you need assistance, Southwest agents at DEN can help with last-minute changes or standby requests.
