Distance & Flight Time

Nonstop flight time is approximately 0h 26m to 2h 15m.
Getting to DFW
DART Orange Line runs from downtown Dallas to Terminal A (50 min, $3). TEXRail serves Terminal B from Fort Worth ($2.50). No direct rail connects both cities to DFW; choose based on your origin. Ride-shares cost $25–45 from either city center.DFW's five terminals span 17,000 acres. The free Skylink people mover connects all terminals airside.
Getting from IAH
No direct rail from IAH. The METRO bus 102 (IAH Express) runs to downtown Houston's transit center (60–90 min, $1.25). Taxis to downtown Houston cost $50–70. Ride-hails pick up at the designated Rideshare zones outside baggage claim on the lower level.IAH has five terminals (A–E) connected by an underground tunnel with trams. Terminal D handles international arrivals. Rental car agencies are in a consolidated facility adjacent to Terminal C; a free IAH Connector bus runs between terminals and the rental car center. The Galleria / Uptown area costs $35–50 by ride-hail.
Houston Climate
Humid subtropical climate. Hot, humid, and wet for much of the year. Summers are brutal (33–38°C) with high humidity and near-daily afternoon thunderstorms. Severe storms with hail and high winds regularly cause ground stops from April through September. Houston's flooding risk is significant. Heavy rain events, including tropical system remnants, have flooded airport roads, cutting off surface access even when the airport itself remains operational.
Winters are mild (5–18°C) with occasional ice storms. These are rare but highly disruptive when they occur. Hurricane season (June–November) requires monitoring for Gulf storms. October through March has the best flying weather.

See the On-Time Performance section for the latest delay data at both airports. This shows departure and arrival reliability to help you plan.
Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
American Airlines and United Airlines are the only nonstop operators between DFW and IAH. At DFW, American uses Terminals A, B, C, and D. At IAH, United operates from its hub in Terminals B, C, D, and E. Check your specific flight number for the terminal assignment, as both airports are large enough that the wrong terminal costs significant time.
Both airports sit in the Texas convective corridor. Summer thunderstorms June through September routinely produce ground delay programs at both ends. On severe storm days, combined delays and cancellations across DFW and IAH can exceed 500 flights system-wide. The 220-mile route is short enough that a one-hour GDP eats the entire flight time. Morning departures before noon consistently outperform afternoon and evening slots for on-time performance.
Amtrak's Sunset Limited connects Dallas and Houston, but the schedule is three times weekly and takes four to five hours. Greyhound and FlixBus run the route in three to four hours. Driving I-45 between the city centres is 240 miles, roughly three and a half hours without traffic. The flight makes sense for travelers originating at or connecting through the airports rather than city-centre-to-city-centre travel.
Dallas Fort Worth to Houston Intercontinental: Texas Hub-to-Hub
DFW-IAH links American Airlines' primary hub to United Airlines' primary Texas hub, making this an unusual pairing where each carrier operates the route on its own turf. Combined nonstop frequency runs around 126 weekly departures. American dominates DFW's capacity while United dominates IAH, so the route primarily serves connecting passengers feeding each carrier's bank. Block time is 76 minutes on a 220-mile segment. Both carriers fly Boeing 737 variants on the route. Frequencies run throughout the day, with no overnight service.
Hub Dynamics and Delay Context
Because both airports are major connecting hubs, delay propagation is significant. A weather ground stop at either end ripples across dozens of connecting banks. IAH is United's fifth-busiest hub globally. DFW is American's largest hub by departures. The Texas convective weather season runs May through October, with July and August showing the highest GDP frequency. Passengers using this flight as a connection leg should be aware that delays on this short segment can cascade across long-haul onward flights.
