What PHX to STL looks like
The PHX to STL sector, the carriers on it and the flying time, before anything is promised to anybody.
Phoenix PHX to St Louis STL is a medium haul sector of 2,027 km by great circle, flown nonstop 6.3 times a day.
At the cruise speed this site models for 2,027 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 3h 05m.
Phoenix PHX is a major hub in the network held here, 172 scheduled destinations and 603.4 departures a day. St Louis STL has 108 destinations and 229.7 departures a day.
Phoenix carries about 2.6 times the departures of St Louis, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
St Louis 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 STL from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| PHX to STL | 6.29 | 44 | American Airlines, Southwest Airlines |
| STL to PHX | 5.43 | 38 | American Airlines, Southwest Airlines |
Two carriers hold the sector, American Airlines and Southwest Airlines, which gives a missed departure somewhere to go without leaving the nonstop.
At 6.3 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 82 departures a week on PHX to STL, 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 3h 05m block time on PHX to STL. 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 STL in the air, estimated | 185 min | 7h 35m |
| Formalities at STL | 90 min | 9h 05m |
| Delivery run in St Louis | 45 min | 9h 50m |
| Door to door | 590 min | 9h 50m |
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 STL is 9h 50m.
A courier who leaves Phoenix at 09:00 local is on the ground in St Louis at about 13:05 local and at the door by 15:20 the same day.
Working backwards from a six in the evening handover in St Louis, the last useful departure from Phoenix is around 11:40 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. 43 of them join PHX to STL.
| Connecting at | PHX to hub, flights a day | Hub to STL, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Kansas City MCI | 6.71 | 3.14 | 2,057 | 4h 43m |
| Omaha OMA | 5.57 | 2.14 | 2,217 | 5h 11m |
| Denver DEN | 25.86 | 11.71 | 2,205 | 5h 19m |
| Dallas DFW | 14.65 | 7.86 | 2,279 | 5h 25m |
| Salt Lake City SLC | 15.86 | 2.71 | 2,674 | 5h 40m |
| Houston IAH | 7.86 | 4.14 | 2,697 | 5h 41m |
With 6.3 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.
43 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Kansas City MCI, where the weaker of the two legs still runs 3.1 times a day.
Through MCI the routing covers 2,057 km against the 2,027 km nonstop track and takes about 4h 43m 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 38m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Omaha OMA at 5h 11m and Denver DEN at 5h 19m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.

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 STL 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.
