The 20 best large airports in the US, according to travelers

• J.D. Power named Louis Armstrong New Orleans International Airport as the top large airport in the US.
• Airport rankings were based on customer surveys, focusing on things like dining options and terminal facilities.
• Customer satisfaction was skewed over the study period due to changing traveler expectations during the pandemic.

J.D. Power revealed its 2021 North America Airport Satisfaction Study, naming Louis Armstrong New Orleans International Airport as the top large airport in the US, earning 844 out of a possible 1,000 customer satisfaction points.

The data analytics company looked at six areas of interest when ranking each airport, including, in order of importance from most to least, terminal facilities; airport arrival/departure; baggage claim; security check; check-in/baggage check; and food, beverage, and retail.

Large airports, which J.D. Power defines as having 10 to 32.9 million passengers per year, received an average score of 805, up 25 points from 2020. Mega airports, which the company defines as having over 33 million passengers per year, received an average score of 798. Overall, customers gave a record-setting average score of 802 for all US airports in the 2021 study.

According to J.D. Power, customer satisfaction was skewed over the year, with the best scores occurring from July 2020 to January 2021 and falling from January 2021 to July 2021. Company analysts say this is because of customer expectations. In the first half of the study, the pandemic was still raging and customers were simply happy to see some amenities available at airports, while in the second half during the travel boom they expected more, but were disappointed with the number of open shops and restaurants.

"Airport customer satisfaction reached all-time highs when passenger volumes were severely suppressed by the pandemic, but as leisure travel rebounded sharply throughout the spring and summer of 2021, we saw an expected downturn in satisfaction. Ultimately, the data conveys changing expectations among travelers. Early in the pandemic, passengers were satisfied with any shop or restaurant being open, but they now expect full service at the airport," explained Michael Taylor, travel intelligence lead at J.D. Power.

According to J.D. Power, passenger volumes have increased to 75% of pre-pandemic levels, but many travelers are arriving at airports with limited food, beverage, and retail vendors. The company explained these are key for a positive airport experience and blame labor shortages for the lack of options.

Here's a closer look at J.D. Power's top 20 large airports for customer satisfaction in the US.
