What CMN to IAD looks like
The CMN to IAD sector, the carriers on it and the flying time, before anything is promised to anybody.
Casablanca CMN to Washington DC IAD is a long haul sector of 6,149 km by great circle, flown nonstop 6 times a week.
At the cruise speed this site models for 6,149 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 7h 54m.
Casablanca CMN is a large airport in the network held here, 104 scheduled destinations and 130.1 departures a day. Washington DC IAD has 270 destinations and 481.8 departures a day.
Washington DC carries about 3.7 times the departures of Casablanca, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Washington DC runs 5 hours behind of Casablanca in January and 4 hours behind in July, because the two ends do not change their clocks together.
The pair sits between Africa and the Americas, a corridor where the site already publishes 2 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on CMN to IAD from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CMN to IAD | 0.86 | 6 | Royal Air Maroc |
| IAD to CMN | 1 | 7 | Royal Air Maroc |
One carrier holds the sector, Royal Air Maroc, so a cancellation has no second nonstop behind it and the connections below stop being theoretical.
Between them the two directions put about 13 departures a week on CMN to IAD, 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 7h 54m block time on CMN to IAD. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to CMN | 90 min | 1h 30m |
| At CMN before departure | 180 min | 4h 30m |
| CMN to IAD in the air, estimated | 474 min | 12h 24m |
| Formalities at IAD | 90 min | 13h 54m |
| Delivery run in Washington DC | 45 min | 14h 39m |
| Door to door | 879 min | 14h 39m |
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 CMN to IAD is 14h 39m.
A courier who leaves Casablanca at 09:00 local is on the ground in Washington DC at about 11:54 local and at the door by 14:09 the same day.
Working backwards from a six in the evening handover in Washington DC, the last useful departure from Casablanca is around 12:51 local.
At 14h 39m the mission uses most of a sixteen hour duty day, which leaves no room for a delay before a rest at the far end becomes the honest answer.
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. 29 of them join CMN to IAD.
| Connecting at | CMN to hub, flights a day | Hub to IAD, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Lisbon LIS | 2.71 | 3.43 | 6,384 | 10h 07m |
| Montreal YUL | 3 | 2.29 | 6,461 | 10h 15m |
| Toronto YYZ | 0.57 | 4.86 | 6,731 | 10h 30m |
| Madrid MAD | 4.43 | 3 | 6,995 | 11h 00m |
| Barcelona BCN | 2.86 | 1.14 | 7,743 | 11h 55m |
| Paris CDG | 7.29 | 4.14 | 8,130 | 12h 26m |
29 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Lisbon LIS, where the weaker of the two legs still runs about twice a day.
Through LIS the routing covers 6,384 km against the 6,149 km nonstop track and takes about 10h 07m in the air and on the ground at the hub, allowing 75 minutes to connect at an airport of that size.
That is only 2h 13m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Montreal YUL at 10h 15m and Toronto YYZ at 10h 30m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Casablanca, Rabat RBA is 109 km away by great circle and carries 43 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
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 CMN to IAD 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.
