What CMB to COK looks like
The CMB to COK sector, the carriers on it and the flying time, before anything is promised to anybody.
Colombo CMB to Kochi COK is a short sector of 506 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 506 km, 720 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 15m.
Colombo CMB is a mid sized airport in the network held here, 45 scheduled destinations and 93.2 departures a day. Kochi COK has 29 destinations and 92.5 departures a day.
Colombo and Kochi keep the same clock all year, so the arrival time is the departure time plus the block and nothing else.
The pair sits inside Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on CMB to COK from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CMB to COK | 1.14 | 8 | SriLankan Airlines |
| COK to CMB | 1.14 | 8 | SriLankan Airlines |
One carrier holds the sector, SriLankan Airlines, so a cancellation has no second nonstop behind it and the connections below stop being theoretical.
Between them the two directions put about 16 departures a week on CMB to COK, 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 1h 15m block time on CMB to COK. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to CMB | 90 min | 1h 30m |
| At CMB before departure | 180 min | 4h 30m |
| CMB to COK in the air, estimated | 75 min | 5h 45m |
| Formalities at COK | 90 min | 7h 15m |
| Delivery run in Kochi | 45 min | 8h 00m |
| Door to door | 480 min | 8h 00m |
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 CMB to COK is 8h 00m.
A courier who leaves Colombo at 09:00 local is on the ground in Kochi at about 10:15 local and at the door by 12:30 the same day.
Working backwards from a six in the evening handover in Kochi, the last useful departure from Colombo is around 14:30 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. 18 of them join CMB to COK.
| Connecting at | CMB to hub, flights a day | Hub to COK, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Bangalore BLR | 2.71 | 14 | 1,077 | 3h 35m |
| Chennai MAA | 7.57 | 5.57 | 1,165 | 3h 43m |
| Male MLE | 8.57 | 1.71 | 1,513 | 4h 14m |
| Hyderabad HYD | 1.86 | 4.43 | 1,946 | 4h 30m |
| Mumbai BOM | 1.51 | 11.29 | 2,590 | 5h 34m |
| Ahmedabad AMD | 0.57 | 1 | 3,423 | 6h 22m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at CMB in the afternoon actually flies on.
18 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Bangalore BLR, where the weaker of the two legs still runs about twice a day.
Through BLR the routing covers 1,077 km against the 506 km nonstop track and takes about 3h 35m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 2h 20m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Chennai MAA at 3h 43m and Male MLE at 4h 14m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Kochi, Thiruvananthapuram TRV is 194 km away by great circle and carries 22 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 CMB to COK 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.
