Main Parking Garages A B C

$42 a day and a 3-minute walk to Terminals 1–3

Main Parking Garages A B C sit right in front of Terminals 1, 2, and 3, with enclosed pedestrian tunnels that put you inside the check-in areas in about 3 minutes. This is ORD’s on-airport daily garage option, aimed at people who value walking over shuttles and accept the $42/day hit for that. Think quick overnight trips, last-minute departures, or days when you can’t risk a shuttle delay.

Rates are a flat $42 per 24 hours in the daily sections, with hourly pricing stepping up to that cap, so anything over about 6–7 hours starts looking like a full day. It’s drive-up only for most travelers; regulars say they save the SpotHero apps for off-site lots and just swallow the garage rate when they need to park feet from Terminals 1–3. No shuttle, no extra check-in time, but you pay airline-lounge money for the space.

Expect real congestion on Sunday nights and around big holidays, with several reviews mentioning 20+ minutes of circling before finding an open stall on upper levels. If you roll in after 7 p.m. on a Sunday, budget that time on top of the 3-minute walk. Exits can also back up, with lines snaking down several levels toward the pay booths during weekday evening waves and late Sunday surges.

Inside, signage is the biggest complaint: people lose their cars after 3–5 day trips because level and row markings on the concrete pillars are easy to overlook. Regulars snap a photo of the level/row and nearby pillar number the second they park. If you land late into Terminal 1, be ready for a slightly eerie walk: the pedestrian tunnel can feel “a bit sketchy” after 11 p.m. when foot traffic thins, even though it’s on airport property.

One niche gotcha: a reviewer said leaving the ticket on a hot dashboard made the barcode unreadable, forcing manual checkout with an attendant and slowing exit by about 10 minutes. Toss the ticket in your wallet instead. Practical play: on peak Sundays, arrive at least 30 minutes earlier than you normally would, just in case the garage is in full-circling mode.
