$2.25 gets you from ORD to Schaumburg, Palatine, and beyond
Pace’s 600-series suburban express buses are built around O’Hare shift changes and school schedules, not tourists on Terminal 1–3 layovers. Fares are a flat $2.25, and typical rides to far northwest suburbs like Schaumburg or Palatine run roughly 45–70+ minutes depending on traffic and the exact route.
These are commuter routes first: lines like 600, 603, 605, 606, and 610 run mainly on weekdays, with limited or zero weekend trips and often just a handful of departures in each direction. Several runs are asymmetric, with strong morning inbound and afternoon outbound service, so a 7:00 a.m. bus from Palatine to O’Hare doesn’t always mean a 7:00 a.m. bus back.
Not every 600-series coach pulls into the terminals; some trips only touch transit centers like Rosemont or other hubs on the Blue Line instead of going to ORD itself. Riders heading from the airport often grab the CTA Blue Line one stop to Rosemont, then transfer to Pace 606 or 610 to reach Woodfield-area offices, Harper College, or other northwest job sites.
Frequency is the main pain point. Miss a peak bus and you can stare down a 60+ minute gap, especially midday or late evening. There’s also very little signage in the terminal complex pointing to specific 600-series stops, so most workers and students use the Pace website or app before leaving Terminal 2 or 3 to confirm exact stop locations and departure times.
Regulars treat the 600-series like a train schedule, not a turn-up-and-go bus. Airport employees build their shifts around specific trips on routes like 600 and 603, and many can recite their departure times by memory. Some locals also pair Metra plus a short 600-series hop, using the bus only for the last few miles from a station in towns such as Schaumburg or Elk Grove.
Step-by-step from ORD, it goes like this: 1) Check pacebus.com for your exact route number (600/603/605/606/610) and trip time that matches your flight. 2) Confirm if that trip serves the terminals or expects you at Rosemont or another transit center. 3) From Terminals 1–3 or 5, follow signs to the appropriate bus/shuttle center or take the Blue Line one stop to Rosemont. 4) Pay the $2.25 fare on board using Ventra or cash. 5) On the return, re-check the timetable; reverse schedules are often weaker than the commute direction.
Practical tip: if your arrival or departure doesn’t line up within about 15–20 minutes of a 600-series trip, don’t wait it out—take the Blue Line or a regular Pace trunk route instead and save the 600-series play for a weekday commute.
