Lehigh Valley International Airport is celebrating a big year. The airport is marking its 90th anniversary.

It unveiled a 24-photo display of its flight through history Wednesday.

One notable moment happened on November 4, 1929, when Amelia Earhart made the first of several trips to the airport.

She was visiting friends who lived locally. The airport's official start date happened months before Earhart's stop-over, in April 1929.

"This is our 90th anniversary, way back in 1929 the Allentown Airport Association received their charter to operate Allentown airport, today LVIA. So a great day to celebrate our customers who helped make 90 years possible," said Thomas Stoudt, Lehigh-Northampton Airport Authority's executive director.

And they've come a long way. Ninety years ago, they started with a 9,600 square-foot hangar with a dirt floor. It cost $18,000 to build back then.
