TAMPA, Fla. (AP) - A one-hour free parking program at Tampa International Airport might be eliminated under a new budget proposal.

Hillsborough County's Aviation Authority will vote on the proposal at its Sept. 2 meeting, when it will adopt a $173.9 million fiscal 2011 budget that takes effect Oct. 1.

Board members learned Thursday that ending the freebie would generate about $2.2 million in revenue annually and help with airport budget constraints

An hour's free parking was introduced in 2005 to reduce vehicle congestion at the arrivals and departure curbsides by providing an alternative to cruising or lingering to pick up or drop off passengers.
