Distance & Flight Time
225 mi / 362 km
Nonstop flight time is approximately 1h 18m to 3h 29m.
Getting to IAH
IAH has no direct rail link to downtown Houston. The IAH Express bus runs from Houston Amtrak/Greyhound station via Park & Ride to Terminal C (60–90 min, $1.25 with METRO Q card). This is the only transit option; Houston's rail network does not reach the airport.Taxis from downtown Houston cost $50–70 and take 40–60 minutes. Ride-hails (Uber, Lyft) are typically $35–55. IAH sits 23 miles north of downtown on the North Freeway (I-45); traffic is heavy during morning and evening rush. Remote economy parking lots serve all terminals via shuttle.
Getting from DFW
DART Orange Line runs to downtown Dallas (50 min, $3). TEXRail reaches downtown Fort Worth in 55 minutes ($2.50). Taxis and ride-shares cost $25–45 to either city center.Rental car facilities are at the south end. All terminals connect via the free Skylink train; this is an airside-only connection, so you must clear security first to use it.
Dallas-Fort Worth Climate
Hot continental climate. Summers are intensely hot (35–40°C) with little rain. Winters are mild (3–12°C) but ice storms hit 2–3 times per year, causing major airport disruptions.
Spring (March–May) brings severe thunderstorms and tornado risk that regularly ground flights. Fall is the best travel window with moderate temperatures and low storm frequency.

Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
United operates from Terminals A, B, C, and E at George Bush Intercontinental. Most IAH-DFW United departures use Terminal C or E. The Skyway people mover connects all terminals airside. At DFW, United does not have a hub presence; United IAH-DFW flights arrive at Terminal E. American dominates DFW and uses Terminals A, B, C, and D.
IAH-DFW operates primarily as a connecting-utility route for passengers who need to reach DFW's American hub connections from IAH, or United's IAH hub connections from DFW. Direct point-to-point passengers are a small share of traffic on this sector. The drive is 3.5-4 hours via I-45 and I-35E; for passengers with tight connections, the 1-hour flight is justified.
Both Houston and Dallas sit in the Gulf Coast convective corridor. Spring (March-May) and early fall (September-October) bring mesoscale convective systems that cause simultaneous ground stops at both airports. When IAH and DFW are both under holds, this route becomes one of the first cut in carrier traffic plans. Summer heat at DFW also causes afternoon thunderstorm cells that slow DFW arrival sequencing. Plan IAH-DFW as a connection segment with at least 90-minute buffer during storm season.
IAH to DFW Route Overview
Houston George Bush Intercontinental to Dallas/Fort Worth is a connecting-utility route that exists primarily to link United's IAH hub with American's DFW hub. United operates the IAH end; American operates sporadic service as well. Combined frequency is 8-12 daily round trips. Flight time is 1 hour 5 minutes. Aircraft are exclusively regional jets: Embraer 175s operated by regional affiliates. The market is dominated by connecting passengers rather than O&D traffic.
Connection and Operational Patterns
The two cities are well within driving distance, so the air route survives primarily on the strength of connecting traffic and corporate travelers unwilling to drive. United's IAH hub feeds passengers from Latin America, the Gulf Coast, and international arrivals to DFW for American connections, and vice versa. This inter-hub routing is unusual and reflects the geographic reality that both Houston and Dallas have major international hubs 380 km apart. Gulf Coast convective weather affects both airports simultaneously during spring and fall, making IAH-DFW one of the routes with the highest likelihood of mutual-airport ground stops in the US network.
