Houston METRO launched a new route directly to George Bush International Airport (IAH) — the 500 IAH Downtown Direct.

Passengers can now catch a non-stop ride directly to and from the George R. Brown Convention Center (GRB) and IAH Terminal C for just $4.50 one way. The route will operate seven days a week, from 5:30 a.m. to 8 p.m., with buses departing every 30 minutes.

METRONow Coming to Life

The launch of the route is part of the METRONow plan, a comprehensive initiative aimed at improving mobility and delivering safe, clean, reliable, and accessible transit options to the region.

“This is a clear example of the METRO that people will choose to use because it’s easy, comfortable, the most cost-effective at only $4.50, and truly the best option,” said METRO Chair Elizabeth Gonzalez Brock. “People needing to get to and from the airport can take this route that offers reduced travel time with a non-stop trip, shaves off time dealing with parking, and saves people money.”

The new service arrives at a critical time as Houston prepares to host the 2026 FIFA World Cup and the George R. Brown Convention Center undergoes a $2 billion transformation into a walkable, convention and entertainment district. 

The 102 Bush IAH Express will continue to serve the airport, but the introduction of the IAH Downtown Direct provides a travel option for riders needing to reach downtown without additional stops.

For customers needing to complete their journey from GRB to other downtown destinations, the Convention District Station, which services the Green and Purple METRORail lines, is immediately adjacent to the 500 IAH Downtown Direct bus stop.

Customers may also download the Ride Circuit app to catch a ride on METRO’s Community Connector for no additional charge. The on-demand, clean energy microtransit service allows riders to reach other METRO services or essential destinations within the downtown zone.
