Flights Casablanca -> Cotonou (CMN-COO) — USD Fares, Airlines, Frequency
3 scheduled departures a week link Casablanca (CMN) in Morocco with Cotonou (COO) — one every 2.3 days on average — flown by 1 catalogued carrier at a scheduled block time near 5.8 hours.
Flight CMN -> COO is operated by Royal Air Maroc (~3 flights per week, ~5.8h block time). This is an intra-Africa + Gulf hub transit corridor. As a rough planning range (an editorial estimate, not an observed fare), economy runs about $500-1,500; the fare observation on this page shows what our weekly snapshot recorded and when. Intra-Africa and Gulf-hub transit fares move week-to-week; 4-8 weeks is the typical sweet spot.
Great-circle distance Casablanca–Cotonou is about 3,175 km, computed from the stored coordinates of CMN (33.37, -7.59) and COO (6.36, 2.38). What the figure fixes is the sector profile — 3,175 km against a scheduled 5.8-hour block time — and the fuel-and-crew economics behind the fare floor. It does not fix a compensation amount. No fixed-tariff compensation scheme reaches CMN–COO. EU261 and UK261 do band by distance, but they only cover flights departing an EU/EEA or UK airport — plus arrivals there on a bloc-licensed carrier — and neither endpoint here is one, whoever operates the flight. The Montreal Convention 1999 is what applies, and it pays provable loss, not a tariff.
Airlines on this route
1 carrier operates CMN–COO: Royal Air Maroc (AT), a full-service airline based in Morocco, a member of Oneworld, with a 23 kg checked-baggage baseline in our table. We estimate about 3 weekly departures on the corridor, with a scheduled block time near 5.8 hours.
| Carrier | Baggage baseline | Alliance |
|---|---|---|
| Royal Air Maroc (AT) | 23 kg | Oneworld |
Our carrier table records a diaspora / migrant-worker baggage uplift of +23 kg on Royal Air Maroc. Read that as a carrier promotion, not a universal entitlement: uplifts of this kind are normally tied to specific fare families and specific corridors, they are rarely honoured on a codeshare or interline segment issued by another airline, and the cheapest promotional fare buckets are the ones most often excluded. Confirm the allowance against your own booking class before you pack to it.
Royal Air Maroc bases its operation at Casablanca (CMN), which is where the corridor’s recovery capacity sits. A hub carrier at the disrupted end has spare aircraft, spare crew and a connecting bank to reflow you through; the same airline at its outstation end usually has one aircraft a day and no local engineering. If the schedule matters, the direction you fly changes your odds.
USD fares — CMN-COO
$817 was the lowest one-way economy price the Travelpayouts feed returned in our weekly snapshot for CMN–COO. That is a single cached observation on this one corridor — not a low across the site’s fare cache, and not a live price — so read it as an observed floor for CMN–COO on that date.
As a rough planning range (an editorial estimate, not an observed fare), economy on CMN-COO runs about $500-1,500; the fare observation on this page shows what our weekly snapshot recorded and when. Cached fares from a weekly Travelpayouts snapshot appear in the panel below, with their observation date; fare-month seasonality follows.
Across the 1 departure month our cache holds a one-way low for, the cheapest reading on CMN–COO was $817 for a Jul 2026 departure and the dearest was $817 for Jul 2026 — a spread of $0 between the best and worst month in the same cache. Month-to-month movement of that size is normal on this corridor and is usually worth more than any single booking trick.
| Departure month | Cheapest one-way seen (USD) |
|---|---|
| Jul 2026 | $817 |
Book 4-8 weeks ahead. Fares rise around the December holidays; mid-week departures are usually the cheapest. That window is general guidance rather than a rule for this single pairing; on a corridor with 3 weekly departures, the practical constraint is often seat availability on the days you can actually travel, not the headline fare.
How much baggage can you take on CMN–COO?
23 kg is the checked-baggage baseline our carrier table records for the 1 airline on CMN–COO, with a recorded diaspora uplift of up to +23 kg on Royal Air Maroc. Baselines are economy figures and fare-family dependent. The allowance printed on your issued ticket overrides any table, this one included.
Read the baseline as an advertised standard rather than a guarantee. Airlines on CMN–COO sell below it through hand-baggage and basic-economy fare families, and those are disproportionately the fares that appear as the corridor’s cheapest quote. The only allowance that binds anyone is the one printed on the ticket you hold.
Where our table records a migrant or diaspora uplift — +23 kg on Royal Air Maroc — three exclusions usually bite. The uplift attaches to nominated corridors rather than the whole network; it rarely survives onto a codeshare or interline segment operated and ticketed by a different airline; and the deepest-discount fare buckets are commonly carved out. None of that makes the uplift fictional, but it does mean it has to be confirmed against your booking class, in writing, before you pack to it.
Is the cheap CMN–COO itinerary really nonstop?
5.8 hours is the scheduled nonstop block time on CMN–COO; any itinerary a search returns well above that is connecting, whatever the screen calls it. “Direct” is a flight-number description, not a promise of a single takeoff and landing. Two separately issued sectors are not one contract.
The distinction is not pedantry. A direct flight keeps one flight number through an intermediate stop, so it can sit in the nonstop filter of a search engine while adding an hour on the ground and a second departure to miss. A connecting itinerary changes flight number and usually aircraft. On CMN–COO the practical test is the elapsed-time figure: compare it against the 5.8-hour block time before you compare prices.
The second trap is the ticket, not the routing. Two cheap sectors bought separately to reach Cotonou are not one contract: your bag is not through-checked, you re-clear security and often immigration at the transfer point, and if the first leg lands late the second airline owes you nothing — no rebooking, no refund, no duty of care. A single ticket that costs more can be the cheaper outcome the first time anything slips.
Search live fares
3 weekly departures across 1 carrier mean a live CMN–COO search returns several price points for the same day; our cached floor for the corridor is $817. Scheduled nonstop block time is 5.8 hours, so any result far above that is connecting whatever the screen says.

Comparing CMN–COO quotes fairly takes three corrections. Passenger count and cabin have to match across the tabs you are comparing. Elapsed time has to be read beside the price, since a connection can add most of a day to the 5.8-hour nonstop. And the baggage line has to be checked, because the cheapest fare family is usually the one carrying the least.
Date flexibility beats every other lever on CMN–COO. Month-scanning surfaces the seasonal shape our fare log records; repeated searching on one fixed date mostly surfaces the same fare bucket. When the calendar is not negotiable — pilgrimage, school holidays, a job start — the useful move is to buy sooner, because scarcity, not timing, is what sets the price then.

Each of those corridors has its own guide with carriers, weekly frequency, scheduled block time and whatever the fare cache holds.
Cotonou, Benin — destination on the intra-Africa + Gulf hub transit corridor. Destination currency: USD (we quote in USD throughout this guide).
Beyond CMN, our catalogue reaches Cotonou from 2 other origins: Accra (ACC) and Lagos (LOS). That matters when the CMN–COO fare is unattractive: on a continent where positioning flights are cheap, flying out of a different gateway is a real option, and each of those corridors has its own guide, carriers and cached fare floor on this site.

The corridor links are there to be used as alternatives, not as further reading. If the CMN–COO fare or schedule does not work, a different African gateway to Cotonou is often the better fix — positioning within the continent is cheap relative to the long-haul sector, and the fare gap between two origins to the same destination is regularly wider than the positioning ticket. The catch is that separately issued sectors carry no protection if the first one runs late.
