Grabbing an airport beer while you’re waiting for your flight is an America tradition. But some of those beers are more affordable than others.

A new report by FinanceBuzz indicates that beer prices can vary as much as $8 at airports across the country. At 12.33 a beer LaGuardia airport in New York needs to be avoided like the plague.

On the other hand, Portland, Oregon has the cheapest airport beer for $4.33 per regular serving, followed by Salt Lake City International Airport ($5.00), Cincinnati/Northern Kentucky International Airport ($5.32), Charlotte Douglas International Airport ($5.50), and San Antonio International Airport ($5.83).

The average cost for a beer across America’s 50 busiest airports is $7.42.

But travelers should plan on shelling out at least $8.30 if they want a brew at any of the 10 most expensive airports in the country. Not that suprisingly, eight of the 10 on the most expensive list sell beer for a full dollar more than the national average.

Beer does tend to be more expensive at the busiest airports in the country. Six of the 10 airports where beer is most expensive also rank in the top 15 in terms of passenger volume according to the survey.

The lowest average beer costs were all found in airports that see fewer passengers.

This survey reflect the average cost of macro brews like Budweiser. Unfortunately we’re not talking craft beers here.
