What PHX to IAH looks like
The PHX to IAH sector, the carriers on it and the flying time, before anything is promised to anybody.
Phoenix PHX to Houston IAH is a medium haul sector of 1,621 km by great circle, flown nonstop 7.9 times a day.
At the cruise speed this site models for 1,621 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 34m.
Phoenix PHX is a major hub in the network held here, 172 scheduled destinations and 603.4 departures a day. Houston IAH has 197 destinations and 641 departures a day.
Houston runs one hour ahead of Phoenix in January and 2 hours ahead in July, because the two ends do not change their clocks together.
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 PHX to IAH from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| PHX to IAH | 7.86 | 55 | American Airlines, Envoy Air, Frontier Airlines, United Airlines |
| IAH to PHX | 7.57 | 53 | American Airlines, Envoy Air, Frontier Airlines, United Airlines |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 7.9 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 108 departures a week on PHX 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 2h 34m block time on PHX 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 PHX | 90 min | 1h 30m |
| At PHX before departure | 180 min | 4h 30m |
| PHX to IAH in the air, estimated | 154 min | 7h 04m |
| Formalities at IAH | 90 min | 8h 34m |
| Delivery run in Houston | 45 min | 9h 19m |
| Door to door | 559 min | 9h 19m |
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 PHX to IAH is 9h 19m.
A courier who leaves Phoenix at 09:00 local is on the ground in Houston at about 12:34 local and at the door by 14:49 the same day.
Working backwards from a six in the evening handover in Houston, the last useful departure from Phoenix is around 12:11 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. 59 of them join PHX to IAH.
| Connecting at | PHX to hub, flights a day | Hub to IAH, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| El Paso ELP | 7.43 | 7.29 | 1,630 | 4h 11m |
| Albuquerque ABQ | 10.14 | 2.86 | 1,724 | 4h 19m |
| Monterrey MTY | 0.86 | 8.14 | 2,092 | 4h 48m |
| Dallas DFW | 14.65 | 19.57 | 1,756 | 4h 49m |
| New Orleans MSY | 1.14 | 9 | 2,578 | 5h 23m |
| Kansas City MCI | 6.71 | 3.86 | 2,714 | 5h 28m |
With 7.9 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.
59 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is El Paso ELP, where the weaker of the two legs still runs 7.3 times a day.
Through ELP the routing covers 1,630 km against the 1,621 km nonstop track and takes about 4h 11m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 1h 37m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Albuquerque ABQ at 4h 19m and Monterrey MTY at 4h 48m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
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 PHX 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.
