MDW is a small single-terminal airport — the one indoor SARA serves the entire airport, and the relief platform inside is tiny (2x4 ft of usable space). Lines can form during peak traffic. Older sources sometimes reference 'Gate A-5' — this was the original location; the airport's own social media confirms the current location is near gate A4A.
1 post-security indoor SARA on Concourse A near gate A4A — fully enclosed room with automatic glass door, ADA-accessible, artificial-grass area, miniature fire hydrant, automatic flushing drain system, mounted shower head with hose, and sink. Plus 1 pre-security outdoor fenced area at the north end of the Lower Level terminal drive (exit Lower Level Door #4 near Baggage Carousel #8).
Fully enclosed room with automatic glass-pane door, ADA-accessible, 2x4 ft artificial grass area with miniature fire hydrant, automatic flushing drain, wall-mounted shower head/hose, and sink. One of the better-built indoor SARAs in the US, though small. Single terminal — serves all gates.
Fenced outdoor area with bench and waste bags. Curbside on the lower level, so road noise is significant. Reviews flag strong ammonia odor.
