Detroit Metropolitan Wayne County Airport ranks highest in passenger satisfaction among mega airports with a score of 786, according to a new study released by J.D. Power, the 2019 North America Airport Satisfaction Study.

The study measures overall traveler satisfaction with mega, large and medium North American airports by examining six factors (in order of importance): terminal facilities; airport accessibility; baggage claim; security check; check-in/baggage check; and food, beverage and retail. Mega airports are those having 33 million or more passengers per year; large airports have 10 to 32.9 million passengers per year; and medium airports have 4.5 to 9.9 million passengers per year.

"The experience of getting through airport security—a perennial drag on airport satisfaction scores—has improved 5 points due to improved TSA processing and more widespread adoption of biometric screening technologies that move passengers through security faster," says the study.
