More and more airports are now serving beer.

In fact, the 50 busiest airports in America are serving a lot of the suds.

But at what price? Having a brew at the Portland Airport in Oregon will only cost you $4.33.

But if you’re at New York’s LaGuardia Airport, that beer will be nearly three times more expensive averaging out at $12.33 a glass.

The cheapest airport beer, in addition to Portland, you’ll find it in Salt Lake City, Cincinnati, Charlotte and San Antonio.

Don’t forget, price notwithstanding, to drink responsibly, especially before boarding your flight.
