A six-level parking garage offers long-term parking on levels three through six. Short-term parking, on levels four and five, has the same hourly rate as long-term parking, but you don't get a discount when you stay for 24 hours.
If you are willing to take a shuttle, you can get lower-cost, long-term parking in the Red and Blue Shuttle Lots. The blue lot offers shuttle service right to your car; the red lot has a central drop-off and an even lower price.
For those who prefer to cycle before flying, the airport has free bicycle parking. The bike parking is on the Departures level, just south of the Skycap area.
