Chicago O’Hare International Airport: Take the CTA Blue Line straight to Logan Square, California, or Western—no transfer. It is about 30–35 minutes to Logan Square station, plus your walk. O’Hare boarding fare is $5; the Blue Line runs 24/7. For one or two people, this beats a taxi or rideshare most of the time.
Chicago Midway International Airport: Take the Orange Line to Clark/Lake, transfer free to the Blue Line toward O’Hare, then exit at Western, California, or Logan Square. Budget 55–70 minutes station-to-station; standard CTA rail fare is $2.50. Midway is workable, but ORD is plainly easier for this neighborhood.
Chicago Union Station: Walk about 10 minutes north to Clinton Blue Line, then ride northwest to Logan Square. Allow roughly 30–40 minutes including the walk and wait. Use a taxi only if you have heavy luggage, a group, or a late-night arrival.
Ogilvie Transportation Center: Walk 5–10 minutes to Clark/Lake and take the Blue Line northwest. Expect 25–35 minutes to Logan Square station.
Millennium Station / LaSalle Street Station: Useful only if your commuter train ends there. From Millennium, walk west to a Loop Blue Line station; from LaSalle, use the nearby Blue Line. Allow 35–45 minutes to Logan Square after walking, waiting, and riding.
