  • The airport project was 16 months behind schedule and had a total cost of $4.8 billion.
  • A blizzard in March 2003 damaged DEN’s white fabric roof, resulting in flight disruptions. Thousands of passengers remained stranded at the airport for two days because of heavy snows and road closures.

How do I get to B Gates?

We assume you mean from the ticketing area. Once you clear security, go down the escalator and take the train. It is one stop to the B gates - very easy!

I will be arriving from Tulsa, OK on a United flight. I then will have to collect my bags and get to whatever terminal Iceland Air is located in to recheck in, drop off bags and re-enter security as I booked these flights separately. I have 4 hours to do this. How do I get between these terminals outside of security? Can I walk it? Or is there an outside connecting train or bus? Thanks for your help.

By Jeanne - Monday, 15 November, 2021, 9:00 AM

Answered By: DEN Airport Staff

To get to the main terminal/baggage claim/ticket counters from the concourse that you arrive on, take the train that runs between the concourses. Once you retrieve you baggage and recheck it at your next airline's ticket counter, you can proceed back through security and out to your departing gate.
