Baltimore/Washington Thurgood Marshall Airport (BWI) serves as the region’s more budget- and leisure-oriented gateway, complementing nearby D.C. hubs. It typically hosts a mix of low-cost carriers and legacy airlines, so fares can often be more competitive than at Reagan or Dulles. The airport lies about 10–12 miles south of downtown Baltimore (roughly 20–30 minutes by car in light traffic). Transit options include the BWI Marshall Rail Station and shuttle connections to the terminals (around 10–15 minutes to the terminal area), light rail and multiple bus lines; taxi or rideshare rides usually take 20–35 minutes depending on traffic with fares varying by route. Pros: usually less crowded and easier parking; cons: farther from some city neighborhoods and can be busy during peak travel times.

Chicago is served by three main airports with different roles. O’Hare International (ORD) is the large international and connecting hub that typically handles most long-haul and legacy-carrier traffic, with United and American among the dominant carriers; it can feel busy but offers extensive route options. Midway (MDW) is a smaller, more budget- and domestic-focused airport where low-cost carriers like Southwest often concentrate their operations; fares here can sometimes be lower for short-haul travel. Travel time to downtown is roughly 30–60 minutes from O’Hare by car or express train (CTA Blue Line) with fares around $5–$40 depending on mode and traffic; Midway is closer, about 15–35 minutes by car or 25 minutes by the Orange Line, with similar fare ranges. Pros: O’Hare’s wide connectivity and full-service amenities versus Midway’s convenience and quicker access for domestic flyers. Cons: O’Hare can be congested and spread out, while Midway has fewer international connections and more limited carrier choice.

The minimum one-way ticket price from Chicago to Baltimore is $61 (October 2025), while the maximum is $79 (January 2026). On average, a ticket costs $70–$79.
