San Antonio to IAH Airport Shuttle
Texas Shuttle runs private, door-to-door shuttle service between San Antonio and George Bush Intercontinental Airport (IAH) — about 208 miles via I-10 East per Rome2Rio, normally a 3 to 3.5 hour run. When a nonstop out of San Antonio International doesn't fit your schedule or price, one reserved vehicle takes you from any address in San Antonio, New Braunfels, or Seguin straight to the IAH curb, 24/7, at a flat rate with no surge.

Where we pick you up and drop you off
For departures to IAH, we pick you up at your exact address — home, hotel, or office anywhere in the San Antonio metro — and take you curbside at your airline's terminal (A through E) on the departures level. For arrivals into IAH headed to San Antonio, your driver meets you at the Ground Transportation area outside baggage claim and texts you the driver's name, vehicle, and live location when you land. We track the inbound flight, so a delayed flight moves your pickup automatically at no extra fee for normal delays.

Recent completed trips on this lane have logged 213–220 miles door-to-door.

Travel tips for the San Antonio–IAH run
- Compare against SAT first. If San Antonio International has your nonstop, our San Antonio airport shuttle page covers the shorter SAT run.
- Corporate travel: this lane is popular for business between the two metros — reserved flat rates and quiet cabin time beat the connection through Hobby.
- Bags and vehicles: two checked bags plus one carry-on per passenger is standard. Note golf clubs, car seats, or oversized items at booking so we size the vehicle correctly.
- Shared vs private: shared rides may include 1–2 extra stops; a private ride is a paid add-on that guarantees the vehicle is just for your party.

San Antonio to IAH: The Complete Transportation Guide
Traveling from San Antonio to George Bush Intercontinental Airport (IAH) covers roughly 200 miles of Texas highway, and choosing the right way to make that trip can mean the difference between a relaxed departure and a stressful race against the clock. Whether you're catching an international flight, connecting through United Airlines' largest hub, or heading to Houston for a cruise-port transfer, this guide breaks down every practical option for getting from the Alamo City to IAH — with real routes, real landmarks, and honest guidance on timing, comfort, and logistics.
Unlike many routes in Texas, San Antonio to IAH has no direct train to the airport and no frequent intercity rail service, so most travelers choose between driving, riding a shuttle, taking a bus, or booking a rideshare. Each option fits a different kind of traveler, and the sections below walk through all of them in detail.
How Far Is San Antonio from IAH?
George Bush Intercontinental Airport sits in north Houston, about 20 miles north of downtown, near the Greenspoint area and the Beltway 8 corridor. From downtown San Antonio, the drive is approximately 190 to 200 miles depending on your route and final terminal. Under normal traffic conditions, expect a drive time of roughly three to three-and-a-half hours. These are estimates — Houston traffic can add an hour or more during rush periods, and construction along I-10 is a recurring reality on this corridor.
For planning purposes, a good rule of thumb is to leave San Antonio at least five hours before a domestic flight and six or more before an international departure. That buffer accounts for Houston-area congestion, parking or drop-off time, and the security process at one of the busiest airports in the United States.
The Drive: Routes from San Antonio to Houston Bush Airport
Primary Route: Interstate 10 East
The most straightforward route follows Interstate 10 East for nearly the entire journey. From San Antonio, you'll merge onto I-10 and pass through a string of classic Texas towns:
- Seguin — roughly 30 minutes east of San Antonio, home to the world's largest pecan statue and a good final fuel stop before the long stretch ahead.
- Luling — famous for its watermelon thump festival and the pump jacks that still dot the town's landscape.
- Waelder and Flatonia — small prairie towns where I-10 opens into wide, fast countryside.
- Katy — the western Houston suburb where you'll first feel the metro area's traffic. The Katy Freeway is one of the widest highways in the world, but it still backs up during peak hours.
As you approach Houston, you have a choice for the final leg to the airport:
- I-10 East to I-610 North: Take the Loop 610 northbound around the city, then connect to U.S. Highway 59 (I-69) north and follow the airport signs via Will Clayton Parkway into the terminal complex. This is the traditional downtown route.
- Sam Houston Parkway (Beltway 8): Many drivers prefer the Sam Houston Tollway's eastern stretch to bypass inner-loop congestion entirely, reaching the airport area from the northeast. Note that Beltway 8 is a toll road and requires an EZ TAG or toll billing.
- Hardy Toll Road: Running north from downtown toward the airport corridor, the Hardy Toll Road is another toll option that can save significant time when I-45 or I-69 are congested.
Alternate Route: SH 130 Toll Road
Travelers departing from northeastern San Antonio or wanting to avoid I-10 truck traffic sometimes take State Highway 130 (SH 130), the high-speed toll road that arcs east of Austin, then connect southeast toward Houston via US 290. This route can be faster in theory, but it adds mileage and toll costs, and it's rarely worth it unless I-10 has a major closure. Check live traffic on TxDOT's DriveTexas tool or a navigation app before committing.
Transportation Options Compared
Here's how the main ways to get from San Antonio to IAH stack up against one another. Costs for paid services vary by provider, demand, and time of day, so treat any figure you see elsewhere as an estimate and confirm directly with the operator.
| Option | Approximate Time | Cost Structure | Best For | Key Drawback |
|---|---|---|---|---|
| Drive yourself | ~3–3.5 hours plus parking | Fuel plus daily airport parking (IAH lots are per-day, see fly2houston.com) | Travelers who want schedule freedom or need a car in Houston | Long-term parking costs add up quickly on multi-day trips |
| Private shuttle or car service | ~3–3.5 hours door to door | Quoted fare — request it from the operator | Families, groups, early-morning flights, business travelers | Must be reserved in advance |
| Rideshare (Uber/Lyft) | ~3–3.5 hours | Surge-priced estimate shown in app at booking | Solo travelers booking last minute | Very high one-way cost for a 200-mile trip; driver availability for long hauls varies |
| Intercity bus (Greyhound/FlixBus) | Roughly 4–5 hours including a transfer, then local transit to IAH | Low fixed fares published on operator sites | Budget travelers with flexible schedules | Buses arrive downtown, not at the airport — requires a second transfer |
| Fly SAT to IAH | ~1 hour flight plus airport time on both ends | Airfare varies by date and airline | Connecting passengers with through-tickets | Almost never worth it as a separate ticket once airport time is counted |
Note: IAH's official airport website, fly2houston.com, publishes current parking rates, terminal maps, and ground transportation updates, and is the most reliable source for airport-specific logistics.
Door-to-Door Shuttle and Private Car Service
For most travelers making this trip for a flight, a reserved shuttle or private car is the sweet spot. A professional driver handles the I-10 grind and the Houston terminal loops while you rest, work, or prep for your flight — and you're dropped directly at your departure terminal curb, skipping IAH parking altogether.
This option makes particular sense when:
- Your flight leaves early. Many IAH departures are before 8 a.m., which would require a midnight or 1 a.m. departure from San Antonio if you drive yourself.
- You're traveling in a group. Splitting a private shuttle among three to six passengers is often comparable to what each person would spend on separate parking, fuel, and wear on a personal vehicle — though exact comparisons depend on quoted fares and trip length.
- You're returning from a long trip. Landing at IAH at 9 p.m. and facing a three-hour night drive back to San Antonio is a poor way to end a vacation.
- You have international luggage. Terminal D and Terminal E at IAH handle most international arrivals, and a curbside pickup eliminates dragging bags through parking garages.
Reputable services will quote you a fixed fare in advance, confirm your pickup window the day before, and track your return flight if you've booked an airport pickup. Texas Shuttle, which operates on this corridor, offers scheduled and charter-style ground transportation between San Antonio and Houston's airports — always confirm your specific pickup time and vehicle type when reserving.
Know Your Terminal: A Quick IAH Orientation
IAH is a large, multi-terminal airport, and knowing your airline's terminal before you travel saves real time at drop-off:
- Terminal A — gates for a mix of domestic carriers
- Terminal B — primarily United Airlines regional and some domestic flights
- Terminal C — United Airlines' main domestic complex
- Terminal D — international departures and a mix of foreign carriers
- Terminal E — United's international hub terminal and federal inspection facilities
United Airlines dominates IAH — it is one of the carrier's largest hubs — so most San Antonio travelers connecting onward through Houston will use Terminals B, C, or E. All terminals are connected post-security by the Subway (Terminal Link) people-mover train, so you can check in at one terminal and reach your departure gate even if drop-off happened at another. Verify your terminal on your airline confirmation or the fly2houston.com terminal map before you leave San Antonio.
What About Flying from SAT to IAH?
It sounds odd, but some travelers wonder whether to simply fly between the two airports. San Antonio International Airport (SAT) — located about eight miles north of downtown off US Highway 281, with Terminal A and Terminal B — does have scheduled service to Houston. However, booking a separate standalone ticket from SAT to IAH almost never makes sense once you account for:
- Drive time to SAT, security, and boarding (easily 2+ hours)
- The short hop itself, plus taxi and deplaning time at IAH
- The total cost compared to ground transportation for a group
The exception: if your onward itinerary already books you as a through connection from SAT via IAH, that's a perfectly sensible routing sold by the airline — just don't create it yourself as two separate tickets.
Timing Your Departure Around Houston Traffic
The Houston metro is one of the most congested driving environments in the country, and the last 40 miles of your trip matter more than the first 150. General patterns to plan around (estimates, not guarantees):
- Weekday mornings (7–9 a.m.): Heavy inbound congestion on the Katy Freeway and inner Loop 610. A shuttle leaving San Antonio at 4:30 a.m. hits Houston before peak — one leaving at 6 a.m. may not.
- Weekday afternoons (4–7 p.m.): The worst window for arrivals into IAH. Add a full hour of buffer if your pickup from San Antonio puts you into Houston in this range.
- Friday afternoons and Sunday evenings: Consistently heavy statewide travel days along I-10.
- Event surges: Houston Rodeo season (early spring at NRG Park, off to the south but affecting overall flow), Astros home games downtown, and major conventions all ripple outward onto the freeways.
Check DriveTexas.org for active TxDOT construction and closure alerts on I-10, I-610, US 290, and the Hardy Toll Road before you leave.
Frequently Asked Questions: San Antonio to IAH
How long does it take to get from San Antonio to IAH?
Approximately three to three-and-a-half hours of driving time for the roughly 200-mile trip under normal conditions. Add buffer for Houston rush hour, I-10 construction zones, and a safety margin before your flight. Most travel planners recommend allocating five hours total before a domestic departure.
Is there a train from San Antonio to Houston's airport?
No. Amtrak's Sunset Limited and Texas Eagle routes do connect San Antonio's station to Houston's Amtrak depot, but service is infrequent (a few departures weekly), arrivals are in downtown Houston rather than at IAH, and schedules are not aligned with flight times. There is no commuter or light-rail connection from downtown Houston to IAH; local transit would require bus connections. For airport travel, ground transportation is the practical choice.
How early should I leave San Antonio for a morning flight at IAH?
For a flight departing IAH between 6 and 8 a.m., plan to leave San Antonio between midnight and 2 a.m. This is the single most common scenario where travelers book a shuttle rather than driving — a professional driver does the overnight highway stretch while passengers sleep.
Which Houston airport should I use — IAH or Hobby?
They serve different airlines and different sides of the city. IAH, in north Houston, is United Airlines' primary Texas hub and handles the majority of international service. William P. Hobby (HOU), south of downtown off I-45 near the Gulf Freeway, is the main base for Southwest Airlines. Your airline and destination determine the airport — not your preference — so confirm your booking before arranging transportation.
Can I park at IAH for a week-long trip?
Yes. IAH offers multiple parking products including terminal garages, ecopark economy lots, and covered options, all with rates published at fly2houston.com. For week-plus trips, economy lots keep costs down, but remember to add parking total to fuel when comparing against a shuttle fare. Reserving parking online in advance is available for some lots.
Do shuttles pick up from my home or hotel in San Antonio?
Private charter and car services generally offer door-to-door pickup anywhere in the San Antonio metro — including the Dominion, Alamo Heights, Stone Oak, and neighborhoods near the airport. Scheduled shared services typically operate from fixed pickup points. Confirm your exact pickup address and window when you book, and be ready 10–15 minutes early.
What happens if my IAH-bound drive hits traffic and I miss my flight?
Build the buffer in advance rather than managing the crisis afterward. Leave five hours before domestic departures and six before international, monitor DriveTexas.org for closures, and consider a pickup time that gets you through Houston before 7 a.m. or after 9 a.m. If a delay is unavoidable, contact your airline immediately through its app — rebooking options are usually better the earlier you act.
Plan the Trip, Not Just the Drive
San Antonio to IAH is a well-worn corridor with plenty of options — the key is matching the option to your flight time, group size, and budget. For solo travelers with midday flights and flexible schedules, driving yourself and using economy parking is a reasonable choice. For early departures, international itineraries, groups, or anyone who'd rather arrive rested than road-weary, a reserved shuttle or private car turns a three-hour haul into the easiest part of the trip. Whichever you choose, check I-10 conditions, know your terminal, and leave more time than you think you need — Texas distances are real, and Houston traffic is, too.
