DIA: Shoes can now stay on through security

What they're saying: The airport predicts the new policy "will create additional efficiencies as it decreases the amount of time it takes for a passenger to move through the screening lane," the airport told Axios Denver in a statement.

• "This change, coupled with cutting-edge technologies of the West and East (opening next month) checkpoints, should continue to create overall efficiencies while ... enhancing security," DIA added.

Zoom out: Other Colorado airports are also adopting the policy, including in Colorado Springs.

The big picture: This is the first time in 19 years that general passengers can skip the TSA's footwear removal policy.

• The unpopular rule has been in place since 2006, five years after an al-Qaeda operative unsuccessfully attempted to detonate a bomb planted in his shoes on a transatlantic flight.

What we're watching: How much the change shaves time off security lines.

• DIA's current wait times year-to-date, according to the airport, hover just under four minutes at the West Security Checkpoint and around 10 minutes at the South Security Checkpoint.
