To find cheap parking at Houston's George Bush Intercontinental Airport, choose an uncovered spot in the ecopark lot; as of October 2015, this section is the cheapest option at the airport for periods of 24 hours or more. The covered ecopark spaces are the next cheapest option. Travelers who are staying at the airport for less than one hour can find cheap parking in the terminal parking garages.
The ecopark lot at George Bush Intercontinental Airport fills up quickly; the best way to secure a cheap parking spot is to reserve it in advance. The ecopark lot accepts prepaid reservations for uncovered spots only. The rate is slightly higher than the drive-up rate, but cheaper than the daily rate for covered spots. Travelers who park in the ecopark lot must allow enough time to take a shuttle to the airport terminal.
The airport also offers covered and uncovered parking in the terminal garages. The 24-hour rates are more than three times the cost of an uncovered ecopark space.
Near the airport, The Parking Spot offers three different lots. Spaces in each lot are slightly cheaper than the onsite ecopark lot. The Parking Spot allows advance reservations, but requires a longer shuttle ride to the terminal than the other lots.
