Travellers aren't very pleased with Toronto Pearson International Airport, according to a new study. 

J.D. Power's 2019 North America Airport Satisfaction Study found that Pearson actually ranked below the average mega airport for customer satisfaction. 

Despite expansion efforts, airports in North America struggle to keep travelers satisfied amid construction delays and surging passenger volumes.

The study ranked mega, large and medium North American airports based on terminal facilities, airport accessibility, baggage claim, security check, check-in/baggage check, and food, beverage and retail. 

Mega airports are those with 33 million or more passengers per year, and Pearson falls into that category. 

The scores from the study are based on a 1,000-point scale and while the average score for a mega airport was 756, Pearson's score was 745. 

In 2018, Pearson ranked much higher at 761, so clearly things have gone downhill within the past year. 

Nineteen airports were ranked in the mega category, and Pearson came in at number 14. 

The number-one airport on the list with a score of 786 was Detroit Metropolitan Wayne County Airport, while the bottom spot was filled by Newark Liberty International Airport with a score of 695. 

Here's the list of 19 North American mega airports. 

1. Detroit Metropolitan Wayne County Airport - 786
