What DFW to IAH looks like
The DFW to IAH sector, the carriers on it and the flying time, before anything is promised to anybody.
Dallas DFW to Houston IAH is a short sector of 362 km by great circle, flown nonstop 19.6 times a day.
At the cruise speed this site models for 362 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 02m.
Dallas DFW is a major hub in the network held here, 287 scheduled destinations and 1,102.3 departures a day. Houston IAH has 197 destinations and 641 departures a day.
Dallas and Houston keep the same clock all year, so the arrival time is the departure time plus the block and nothing else.
The pair sits inside the Americas, a corridor where the site already publishes 13 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on DFW to IAH from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| DFW to IAH | 19.57 | 137 | Air France, American Airlines, Lufthansa, Mesa Airlines, Qatar Airways, United Airlines |
| IAH to DFW | 18.58 | 130.1 | American Airlines, National Airlines, United Airlines |
7 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 19.6 times a day there is usually another departure within a few hours, which is what makes a same day booking on this pair realistic.
Between them the two directions put about 267.1 departures a week on DFW to IAH, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 1h 02m block time on DFW to IAH. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to DFW | 90 min | 1h 30m |
| At DFW before departure | 180 min | 4h 30m |
| DFW to IAH in the air, estimated | 62 min | 5h 32m |
| Formalities at IAH | 90 min | 7h 02m |
| Delivery run in Houston | 45 min | 7h 47m |
| Door to door | 467 min | 7h 47m |
On the desk standard ground timings, ninety minutes to collect and reach the airport, three hours at the airport before departure, ninety minutes of arrival formalities and a forty five minute delivery run, the door to door figure for DFW to IAH is 7h 47m.
A courier who leaves Dallas at 09:00 local is on the ground in Houston at about 10:02 local and at the door by 12:17 the same day.
Working backwards from a six in the evening handover in Houston, the last useful departure from Dallas is around 14:43 local.
When the nonstop does not work
Every airport that joins the two ends, ranked by when they land, among the ones whose weaker leg is dependable enough to plan on. Connection time is allowed for the size of the hub. 84 of them join DFW to IAH.
| Connecting at | DFW to hub, flights a day | Hub to IAH, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| New Orleans MSY | 8.86 | 9 | 1,208 | 3h 47m |
| Monterrey MTY | 7.29 | 8.14 | 1,507 | 4h 03m |
| Mobile MOB | 3.57 | 4.57 | 1,552 | 4h 07m |
| Memphis MEM | 7.71 | 5.14 | 1,447 | 4h 08m |
| Birmingham BHM | 6.86 | 5.14 | 1,863 | 4h 22m |
| Kansas City MCI | 8.43 | 3.86 | 1,779 | 4h 25m |
With 19.6 times a day on the nonstop, a connection here is a disruption plan rather than a routing, and it is listed because a closed runway or a cancellation wave is exactly when nobody has time to work it out.
84 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is New Orleans MSY, where the weaker of the two legs still runs 8.9 times a day.
Through MSY the routing covers 1,208 km against the 362 km nonstop track and takes about 3h 47m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is 2h 45m more than the nonstop, which is the price of a missed departure on this pair.
Behind it, Monterrey MTY at 4h 03m and Mobile MOB at 4h 07m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
The two ends are only 362 km apart in a straight line. Allowing a road track a quarter longer than that and eighty kilometres an hour, a car covers it in about 5h 39m, so a courier who misses the flight drives rather than connects, and on a short deadline the road is often the plan from the start.
If nothing suitable leaves Dallas, Dallas DAL is 18 km away by great circle and carries 190 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves Houston, Houston HOU is 38 km away by great circle and carries 145 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.

Where this came from, and where to look next
- Carriers and frequencies: AeroDataBox scheduled route statistics, retrieved 2026-09-07. Average daily flights, not a timetable.
- Distances: great circle from published coordinates. They read short against a flown track, which is why the block time above applies a factor to them.
- Block and connection times: the same model the route calculator lower down this page runs, at the same rounding.
- Restrictions: the airport notes file, checked 2026-09-07.
- Industrial sites: public company information. Nothing here says or implies that any company named is a customer of any courier operator.
Who publishes this. OnBoard Courier is a placement desk in Dubai. An assignment is carried out by a vetted partner operator, with the desk as the single point of contact from the quote to the signature. This page exists because our own dispatchers need the answer for DFW to IAH in the twenty minutes before a promise is made, and a reference only one operator can read is not a reference. Free to read, quote and cite. Found an error? Tell us and we will correct it.
If you need something moved rather than looked up, the desk prices a hand carry in fifteen minutes.
