Houston IAH Skyway runs inside security; the Subway links public areas and the Marriott. The station lists and service windows differ.
Where to start
Determine your current security status and destination. Don't add a terminal to the published station list or turn a station-to-station time into a connection guarantee.

Changes and service warnings
Check the effective date and the current operator notice before following a saved route.
Terminal B North check-in detour
The airport banner directs some B North passengers to Terminal C departures for check-in, security and access even while some B North gates operate. No B lobby reopening date was established.
What remains to confirm
Before you use one of these routes, check the operating carrier, flight date and current stop with the airport or transport provider. These records can’t tell you whether your bag is checked through, whether you may enter the country, how long the queues are or whether you have enough time to connect.
