DIA nets below-average customer satisfaction score

• Seven criteria determine the score on a 1,000-point scale, including ease of travel through the airport, level of trust and airport staff.

Why it matters: Despite the small jump, DIA still lags behind the average satisfaction score (603) for similarly sized airports for the second consecutive year.

Context: DIA opened its new 17-lane east security checkpoint last month, with airport officials saying it would help improve safety and efficiency for passengers, who often complained about long security lines.

By the numbers: More than 10 million people passed through TSA checkpoints at North American airports this Labor Day weekend, setting a record for air travel volume, per JD Power.
