What CCU to HAN looks like
The CCU to HAN sector, the carriers on it and the flying time, before anything is promised to anybody.
Kolkata CCU to Hanoi HAN is a medium haul sector of 1,797 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 1,797 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 48m.
Kolkata CCU is a mid sized airport in the network held here, 51 scheduled destinations and 142.9 departures a day. Hanoi HAN has 87 destinations and 368.8 departures a day.
Hanoi 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.
Hanoi is 1.5 hours ahead of Kolkata all year.
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.

Between them the two directions put about 16 departures a week on CCU to HAN, 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 48m block time on CCU to HAN. Change any of them in the tool further down and the total moves with them.

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. 14 of them join CCU to HAN.
| Connecting at | CCU to hub, flights a day | Hub to HAN, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Yangon RGN | 0.57 | 0.71 | 2,151 | 4h 45m |
| Kunming KMG | 1 | 1.14 | 2,019 | 4h 56m |
| Bangkok DMK | 1 | 2.29 | 2,591 | 5h 18m |
| Bangkok BKK | 3.43 | 12.86 | 2,632 | 5h 36m |
| Guangzhou CAN | 1.14 | 7.86 | 3,349 | 6h 32m |
| Hyderabad HYD | 6.43 | 0.57 | 4,113 | 7h 16m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at CCU in the afternoon actually flies on.
14 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Yangon RGN, where the weaker of the two legs still runs 4 times a week.
Through RGN the routing covers 2,151 km against the 1,797 km nonstop track and takes about 4h 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 57m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Kunming KMG at 4h 56m and Bangkok DMK at 5h 18m 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 CCU to HAN 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.
