What IAD to PHX looks like
The IAD to PHX sector, the carriers on it and the flying time, before anything is promised to anybody.
Washington DC IAD to Phoenix PHX is a medium haul sector of 3,142 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 3,142 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 4h 17m.
Washington DC IAD is a major hub in the network held here, 270 scheduled destinations and 481.8 departures a day. Phoenix PHX has 172 destinations and 603.4 departures a day.
Phoenix runs 2 hours behind of Washington DC in January and 3 hours behind 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.

Between them the two directions put about 17 departures a week on IAD to PHX, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature

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 IAD to PHX is 11h 02m.

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. 52 of them join IAD to PHX.
| Connecting at | IAD to hub, flights a day | Hub to PHX, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Kansas City MCI | 2.57 | 6.29 | 3,164 | 6h 03m |
| Washington DC DCA | 0.57 | 3.29 | 3,216 | 6h 08m |
| Baltimore BWI | 0.71 | 4.43 | 3,283 | 6h 13m |
| St Louis STL | 2.43 | 5.43 | 3,145 | 6h 16m |
| Columbus CMH | 7.29 | 2.43 | 3,164 | 6h 23m |
| Pittsburgh PIT | 4.86 | 2.14 | 3,206 | 6h 24m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at IAD in the afternoon actually flies on.
52 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 about twice a day.
Through MCI the routing covers 3,164 km against the 3,142 km nonstop track and takes about 6h 03m 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 46m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Washington DC DCA at 6h 08m and Baltimore BWI at 6h 13m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Washington DC, Washington DC DCA is 38 km away by great circle and carries 112 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 IAD to PHX 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.
