Houghton County Memorial Airport (CMX)

Houghton County Memorial Airport (CMX) is a critical regional link for Michigan's Upper Peninsula, with most connections flowing to Chicago O'Hare (ORD) via United Express. When departing from CMX, arrive at least 90 minutes early; although the terminal is small, United Express (operated by SkyWest) strictly requires bags to be checked in 75 minutes prior to departure. The TSA checkpoint has only one lane, but processing is typically efficient. For those connecting in Chicago (ORD), United flights usually arrive at Terminal 1 or Terminal 2. These terminals are connected airside, allowing you to walk to your next gate without re-clear security. However, if your connection is in Terminal 5 (International), utilize the airside Terminal Transfer Bus (TTB) from Gate B1 or F3 to avoid the landside ATS train and subsequent security re-entry. A unique factor for CMX travelers is the heavy lake-effect snow; while the airport is highly experienced in snow removal, visibility can frequently cause delays. United's 'Connection Saver' tool may hold your ORD flight for a few minutes if your inbound from CMX is slightly late. If your connection is canceled due to weather, rebooking is handled through the United app, but be aware that the next available flight might not be until the following day. Ground transportation at CMX is limited to rental cars and local taxis, so pre-arranging your pickup is essential. For those with a long layover at ORD, the Blue Line train provides a 45-minute direct link to downtown Chicago, with the station located on the lower level of the main terminal complex.
