Travelers have long grumbled that Minneapolis-St. Paul International Airport is expensive, and a new report by Lets Fly Cheaper confirms it.

Technically, MSP did not land on the website's list of the 20 most expensive places to catch a flight. But that's mainly because the survey did not include airports like MSP, where a majority of the flights are operated by regional carriers such as Mesaba and Pinnacle airlines.

The average round trip domestic ticket in the Twin Cities is $448.70, which would have landed it fifth on the list.

It could be worse. Topping the list are three United Airlines hubs, Houston Bush ($517.50), Washington Dulles ($504.20) and Newark Liberty ($480.30) airports. Dallas-Fort Worth at $449.40 was No. 4.
