- Long-Term parking at $11 a day is the cheapest option, and the airport says the price you see is the price you pay with no hidden fees.
- Use the rail station garage at $12 a day if you are arriving by train, and check the rail shuttle schedule before you go.
- The Hourly Garage is closest to the terminal and worth the extra cost for a short trip.
- Check which checkpoint your airline uses before you walk in, so you do not join the wrong security line.
- The Long-Term shelters have real-time monitors that show when the next shuttle arrives, which helps on early departures.
