The Washington Dulles International Airport is among the most expensive airports in the nation for passengers, according to a new report.
That makes it the ninth most expensive airport in the nation.
The national average is $339.71.
The price is determined by individual airlines, not the airport, so airports that serve as a hub are often greatly impacted by the prices of one specific carrier.
Prices are up an average $33 over a year earlier.
"The airlines were constantly putting something on sale simply because fewer people were traveling," Trippler said. Now prices are up because fewer seats are available.
Still, airline prices are below their peak in 2008. Trippler expects fares to hold steady for the foreseeable future.
