Five-minute shuttle beats circling the IAH garages
PreFlight Airport Parking sits at 3100 Greens Road, about 3.8 miles from IAH, and runs as an off-site economy lot with its own 24/7 shuttle loop. You park at a fixed location, keep your keys, and ride in instead of hunting for a spot in the airport garages at Terminals A, B, C, D, or E.
Shuttles run roughly every 5–7 minutes, with a posted ride time of about 5–10 minutes to the terminals. That means you should budget 15–20 minutes from gate check-out at your car to curbside at IAH, which is still often faster than snaking up and down the on-airport ramps looking for a space.
This is true off-site economy pricing, usually under cutting the on-airport garages by several dollars per day, while still dropping you at the commercial curb near your airline at Terminals A through E. You pay for the stall, the shuttle ride is included, so there’s no per-bag or per-person fee stacking up for a family or work group.
The weak spot is overnight and early-morning waits: reviews flag that shuttle timing can stretch beyond the standard 5–7 minute promise after midnight. PreFlight posts a phone line with specific notes that calling after midnight or from Terminals D and E can trigger faster pickup, so build in a buffer if you land at 01:00 or later.
Regulars use a simple play: when they land at D or E, they call the posted shuttle number as soon as the aircraft parks, instead of waiting until they reach the curb. That 5-minute head start usually syncs the 5–10 minute shuttle run from Greens Road with your walk out of Terminals D or E.
Pro tip: on departure, aim to arrive at PreFlight 60–75 minutes before boarding time; that covers a 5–10 minute shuttle to IAH, a quick bag drop, and typical security at A, B, C, D, or E.
