What DEL to CCU looks like
The DEL to CCU sector, the carriers on it and the flying time, before anything is promised to anybody.
Delhi DEL to Kolkata CCU is a medium haul sector of 1,313 km by great circle, flown nonstop 25.9 times a day.
At the cruise speed this site models for 1,313 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 11m.
Delhi DEL is a large airport in the network held here, 133 scheduled destinations and 607.8 departures a day. Kolkata CCU has 51 destinations and 142.9 departures a day.
Delhi carries about 4.3 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.
Delhi 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 DEL to CCU from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| DEL to CCU | 25.89 | 181.2 | Air India, IndiGo, Starlight Airline, SpiceJet |
| CCU to DEL | 20.09 | 140.6 | Air India, IndiGo, SpiceJet, Starlight Airline |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 25.9 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 321.9 departures a week on DEL 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 11m block time on DEL 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 DEL | 90 min | 1h 30m |
| At DEL before departure | 180 min | 4h 30m |
| DEL to CCU in the air, estimated | 131 min | 6h 41m |
| Formalities at CCU | 90 min | 8h 11m |
| Delivery run in Kolkata | 45 min | 8h 56m |
| Door to door | 536 min | 8h 56m |
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 DEL to CCU is 8h 56m.
A courier who leaves Delhi at 09:00 local is on the ground in Kolkata at about 11:11 local and at the door by 13:26 the same day.
Working backwards from a six in the evening handover in Kolkata, the last useful departure from Delhi is around 13:34 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. 30 of them join DEL to CCU.
| Connecting at | DEL to hub, flights a day | Hub to CCU, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Lucknow LKO | 12.26 | 1.43 | 1,312 | 3h 45m |
| Ranchi IXR | 7.84 | 3.86 | 1,336 | 3h 46m |
| Patna PAT | 14.23 | 2.14 | 1,329 | 3h 48m |
| Varanasi VNS | 7.44 | 1.29 | 1,314 | 3h 56m |
| Jaipur JAI | 5.36 | 3.14 | 1,589 | 4h 04m |
| Siliguri IXB | 9.86 | 5.43 | 1,573 | 4h 06m |
With 25.9 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.
30 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Lucknow LKO, where the weaker of the two legs still runs about once a day.
Through LKO the routing covers 1,312 km against the 1,313 km nonstop track and takes about 3h 45m 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 34m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Ranchi IXR at 3h 46m and Patna PAT at 3h 48m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
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 DEL 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.
