"North America airports have been doing a tremendous job managing passenger volume, adding amenities, and keeping travelers moving despite some noteworthy challenges, but they will be put to the true test over the next few years," said Michael Taylor, Travel Practice Lead at J.D. Power. "Several multi-billion-dollar airport construction projects—such as those in Boston, Los Angeles and Chicago—are reaching phases in which passenger disruption and increased traffic will be incredibly hard to avoid. How well these rapidly expanding airports manage throughout these infrastructure projects will provide valuable insight into what's in store on a nationwide basis."

Following are some of the key findings of the 2018 study:

• Overall satisfaction reaches all-time high: Overall customer satisfaction scores reach an all-time high of 761, which is up 12 points from last year's previous record high. Improvement is driven primarily by a 17-point increase in satisfaction with food, beverage and retail, and an 18-point increase in satisfaction with security check.

• Better airport/TSA communication improves security check satisfaction: The 18-point increase in passenger satisfaction with the security check process is largely attributable to improved communication and cooperation between airport and TSA staff, with leading airports working closely with TSA to align security staffing levels with airport load factors.

• Outsmarting human nature: The highest-scoring component of the airport experience is check-in/baggage check, which has been rising consistently since airports began implementing self-service kiosks and bag tagging. This removes the passenger frustration of waiting for someone else to facilitate a process, reduces lines and allows passengers to move at their own pace.

The 2018 North America Airport Satisfaction Study measures overall traveler satisfaction with mega, large, and medium North America airports by examining six factors (in order of importance): terminal facilities; airport accessibility; security check; baggage claim; check-in/baggage check; and food, beverage and retail.

Now in its 13^th year, the study is based on responses from 40,183 North America travelers who traveled through at least one domestic airport and covers both departure and arrival experiences (including connecting airports) during the past three months. Travelers evaluated either a departing or arriving airport from their round-trip experience. The study was fielded from September 2017 through September 2018.
