Airport vendor draws scrutiny for selling $27 beer at LaGuardia

State transportation officials are tightening the rules on concessions prices at New York City-area airports after finding one vendor charging as much as $27 for a beer at LaGuardia.

The policy changes come after a probe prompted by a traveler's complaint last year on social media about the listed prices of a seasonal beer, which exceeded $27, said the Port Authority of New York and New Jersey, which regulates LaGuardia, John F. Kennedy and Newark Liberty airports. 

"Nobody should have to fork over such an exorbitant amount for a beer," Port Authority Chairman Kevin O'Toole said in announcing stronger measures to curtail the practice. Airport concession prices are capped at what would be charged locally, plus an additional 10%.
