WiFi & Connectivity
Stay connected at Baltimore/Washington International Thurgood Marshall Airport — free WiFi, eSIM options and local data for United States.
Airport WiFi at BWI
No registration required — connect and browse immediately.
Connecting is just a tap-to-accept splash screen with no personal details required, so there's little reason to rely on a local SIM just for airport wifi — but if you need reliable data beyond the terminal, a US eSIM is worth arranging in advance.
It's described as commercial-free and unlimited, which holds up well in practice — good enough for video calls, not just checking email.
