What KHI to ISB looks like
The KHI to ISB sector, the carriers on it and the flying time, before anything is promised to anybody.
Karachi KHI to Islamabad ISB is a short sector of 1,107 km by great circle, flown nonstop 9.9 times a day.
At the cruise speed this site models for 1,107 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 1h 55m.
Karachi KHI is a smaller airport in the network held here, 28 scheduled destinations and 66.4 departures a day. Islamabad ISB has 31 destinations and 63 departures a day.
Karachi and Islamabad 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 KHI to ISB from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| KHI to ISB | 9.95 | 69.6 | Airblue, Pakistan International Airlines, Air Sial |
| ISB to KHI | 9.33 | 65.3 | Air China, Airblue, Pakistan International Airlines, Air Sial |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 9.9 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 135 departures a week on KHI to ISB, 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 55m block time on KHI to ISB. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to KHI | 90 min | 1h 30m |
| At KHI before departure | 180 min | 4h 30m |
| KHI to ISB in the air, estimated | 115 min | 6h 25m |
| Formalities at ISB | 90 min | 7h 55m |
| Delivery run in Islamabad | 45 min | 8h 40m |
| Door to door | 520 min | 8h 40m |
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 KHI to ISB is 8h 40m.
A courier who leaves Karachi at 09:00 local is on the ground in Islamabad at about 10:55 local and at the door by 13:10 the same day.
Working backwards from a six in the evening handover in Islamabad, the last useful departure from Karachi is around 13:50 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. 16 of them join KHI to ISB.
| Connecting at | KHI to hub, flights a day | Hub to ISB, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Lahore LHE | 10.29 | 2.14 | 1,292 | 3h 42m |
| Quetta UET | 2.57 | 1.86 | 1,261 | 3h 52m |
| Muscat MCT | 1.29 | 1.57 | 2,709 | 5h 28m |
| Sharjah SHJ | 3.43 | 5.14 | 3,078 | 5h 56m |
| Dubai DXB | 7.57 | 6.14 | 3,111 | 6h 28m |
| Abu Dhabi AUH | 4.3 | 2.71 | 3,298 | 6h 28m |
With 9.9 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.
16 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Lahore LHE, where the weaker of the two legs still runs about twice a day.
Through LHE the routing covers 1,292 km against the 1,107 km nonstop track and takes about 3h 42m 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 47m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Quetta UET at 3h 52m and Muscat MCT at 5h 28m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.

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 KHI to ISB 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.
