That money will go into airport operating funds, not construction of more parking space. The Parking Authority also says it has trimmed operating costs since it took over management of the lots and garages last fall from a 30-year series of private operators.
Under private management, airport parking was twice the scene of major scams in which dishonest cashiers skimmed thousands of dollars from parking proceeds - most recently, leading to 17 convictions in a mid-1990s scandal.
Meanwhile, unrelated contracts at the airport have been a focus of federal prosecutors in the ongoing city corruption scandal.
The current parking problems develop, naturally enough, in the economy lot first.
"We've been filling the economy lot by Tuesday or Wednesday every week," said the Parking Authority's Miller.
Last Wednesday, for example, the economy lot was closed by 8 a.m., the garages for terminals C and D by 8:15, the garage for terminal B by 8:40 and even the last garages in line, at terminals E and F, by 11:42, Miller said.
By Thursday morning, Miller reported the lots were open again after returning travelers pulled out of their spaces.
The Parking Authority plans to add about 300 spaces to the economy lot by September, said Miller.
Parking and airport officials also are talking about adding more spaces elsewhere at the airport, possibly in the area of the terminal E and F garage. But that could require expanding or building more garage space - a time-consuming process that could take years from bond issue to completion.
Officials say parking spots are hard to come by because low-fare carrier Southwest Airlines, which began operating out of Terminal E in May of last year, is drawing far more passengers...
Both the 18,000 parking spaces in the airport's garages and economy lot, as well as 18,000 spaces in private lots surrounding the airport, are often full, especially on holiday weekends.
Fee hike would help pay for new garage.
The money would pay for a third north-south runway, new taxiways, extensive road expansion, more parking, and a new north terminal with a 14-gate airside.
