What BOM to CCU looks like
The BOM to CCU sector, the carriers on it and the flying time, before anything is promised to anybody.
Mumbai BOM to Kolkata CCU is a medium haul sector of 1,666 km by great circle, flown nonstop 12.7 times a day.
At the cruise speed this site models for 1,666 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 38m.
Mumbai BOM is a large airport in the network held here, 106 scheduled destinations and 372.3 departures a day. Kolkata CCU has 51 destinations and 142.9 departures a day.
Mumbai carries about 2.6 times the departures of Kolkata, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Mumbai and Kolkata 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 BOM to CCU from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| BOM to CCU | 12.71 | 89 | Air India, Air India Express, IndiGo, Starlight Airline |
| CCU to BOM | 0 | 0 | none held |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
The return leg CCU to BOM carries no scheduled nonstop at all, so a courier coming back does it with a connection.
At 12.7 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 89 departures a week on BOM to CCU, 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 2h 38m block time on BOM to CCU. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to BOM | 90 min | 1h 30m |
| At BOM before departure | 180 min | 4h 30m |
| BOM to CCU in the air, estimated | 158 min | 7h 08m |
| Formalities at CCU | 90 min | 8h 38m |
| Delivery run in Kolkata | 45 min | 9h 23m |
| Door to door | 563 min | 9h 23m |
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 BOM to CCU is 9h 23m.
A courier who leaves Mumbai at 09:00 local is on the ground in Kolkata at about 11:38 local and at the door by 13:53 the same day.
Working backwards from a six in the evening handover in Kolkata, the last useful departure from Mumbai is around 13:07 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. 26 of them join BOM to CCU.
| Connecting at | BOM to hub, flights a day | Hub to CCU, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Ranchi IXR | 1.71 | 3.86 | 1,701 | 4h 14m |
| Nagpur NAG | 6.43 | 1.14 | 1,668 | 4h 15m |
| Indore IDR | 6.14 | 1.14 | 1,803 | 4h 24m |
| Hyderabad HYD | 15.29 | 6.43 | 1,831 | 4h 28m |
| Patna PAT | 3.86 | 2.14 | 1,921 | 4h 33m |
| Varanasi VNS | 4.57 | 1.29 | 1,894 | 4h 33m |
With 12.7 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.
26 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Ranchi IXR, where the weaker of the two legs still runs about once a day.
Through IXR the routing covers 1,701 km against the 1,666 km nonstop track and takes about 4h 14m 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 36m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Nagpur NAG at 4h 15m and Indore IDR at 4h 24m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Mumbai, Pune PNQ is 124 km away by great circle and carries 34 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves Kolkata, Dhaka DAC is 239 km away by great circle and carries 49 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 BOM to CCU 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.
