Travelers want more outlets and faster Wi-Fi. Airlines want more gates. Everyone wants more efficient security lines.

Denver International Airport CEO Kim Day addressed those wants Thursday afternoon in front of about 400 attendees at “The Future of Metro Mobility: Planes, Trains and (Self-Driving) Automobiles.” The event was at the Denver Center for the Performing Arts.

Overall traffic at DIA is up 6 percent year to date, Day said. That means gates are in high demand. Airlines have requested to add 20 new gates by 2020, airport spokeswoman Stacey Stegman said.

Dave & Buster’s making furloughs permanent at Colorado locations

Colorado is making progress on a Front Range railway. Here’s what it will take to make it happen.

United Airlines updates Denver furlough plan, more than 900 workers to be sent home after Oct. 1 “That’s no problem,” Day said. “Our airport was designed to grow — just not this fast. By telescoping out Concourses A, B and C to their maximum length, we will be putting even more pressure on the train that connects the concourses to the terminal, so we’ll be adding a train set over the next few years.”

Sixty-five percent of DIA’s traffic begins and ends in Denver, while 35 percent comes from connecting flights, Day said. Original projections had predicted a higher share traffic coming from connecting flights.

The airport plans to add 10,000 power outlets in concourse seating areas by the end of summer, Day said. Other plans include consolidated ticket lobbies and the relocation of TSA to the sixth floor from the Great Hall by 2019.

In the open space, “imagine something very Colorado,” Day said, including Colorado sports apparel shops and Colorado-branded restaurants and experiences.

“Yes, zip lining is a possibility,” she said.

Despite what can sometimes seem like never-ending lines at ticket counters, technology has lessened the crush because passengers can download boarding passes directly to their phones.

“Ticket counters are almost obsolete,” Day said.

The No. 1 passenger complaint at DIA is long lines at security, Day said. She said that stems from perception. Most days, she said, actual security checkpoint wait times are at or below the national average. But stress sets in when passengers see the long lines from a level above.

“Plus, you don’t want to disrobe in that big open space,” she joked.

To make the process less stressful, DIA created the Canine Airport Therapy Squad — emphasis on the dogs, not CATS — in October 2015.

“They are among our most popular staff,” Day said.

DIA isn’t the only airport with animals to comfort passengers. Day said her staff is thinking about a miniature pony to compete with San Francisco’s potbelly pig. She did not say what hashtag would be implemented to beat out #whenpigsfly.

In the future, Day said she would like to see more pushes of personalized information to customers’ phones. That could include information about eateries near an arrival gate or a drink order sent in advance to a coffee shop down the concourse.

DIA has taken advantage of some customers’ technology. The airport uses Bluetooth to track passengers’ time in line at TSA for those who have it turned on.

Also presenting at the Metro Mobility event were Panasonic Enterprise Solutions CEO Jim Doyle and McKinsey and Co. partner Philipp Kampshoff.

Doyle spoke about Panasonic’s plans to locate a technology center near the airport. The plans are based on the “sustainable smart town” in Fujisawa, Japan. Think housing communities with no parking spaces. Employees take mass transit to work.

Autonomous driving is another priority of Panasonic.

Kampshoff said autonomous vehicles are the true game changer. “Some would say that the industry’s close to change more over the next five years than it has in the last 50 years altogether. Some say 10 years, but nevertheless, the change is going to be very, very significant.”

Benefits of autonomous cars include increased personal safety, enhanced mobility for non-drivers and reduced per-mile transportation costs, he said.

Denver Mayor Michael Hancock was scheduled to make opening remarks at the event, but he was in Washington, D.C., pitching Denver’s Smart City application. Denver is one of the competition’s seven finalists. The winner may receive up to $40 million in investment from the U.S. Department of Transportation.
