Chicago to Dhaka
16h 11mgate to gate
The flight from Chicago O'Hare International Airport (ORD) to Hazrat Shahjalal International Airport (DAC) covers 12,694 km (7,888 miles) and takes approximately 16h 11m gate to gate for a typical jet.
The route heads north on an initial great-circle bearing of 2°, passing near 80.8° N, 83.1° E at its midpoint.

How this is worked out
- Take both airports' published coordinates from OurAirports — nothing here is scraped from another flight site.
- Great-circle distance by haversine on a mean earth radius of 6,371.0088 km: 12,694 km.
- Airborne time = that distance ÷ 805 km/h, a representative jet cruise speed: 15h 46m.
- Add a flat 25 minutes for pushback, taxi, climb, descent and taxi-in — the reason a 400 km hop is never half an hour: 16h 11m gate to gate.
- Winds, aircraft type and airline schedule padding are not modelled. The cruise-speed table shows how much that assumption is worth.
12,694 km / 805 km/h = 15h 46m airborne
+ 25 min ground = 16h 11m gate to gate

The same route, plotted on a world grid
The strip above gives the route its length and its shape. This gives it a position: latitude and longitude only, no coastlines, because a hand-drawn coastline would be decoration pretending to be data. On a flat grid the shortest path looks bent; on a globe it is straight.
Flight time at different cruise speeds
Aircraft type, winds and routing all move the real number. This is the same distance flown at different speeds, plus the 25-minute ground and climb allowance.
| Typical of | Cruise speed | Airborne | Gate to gate |
|---|---|---|---|
| Turboprop / regional | 550 km/h | 23h 05m | 23h 30m |
| Narrowbody jet (A320, 737) | 780 km/h | 16h 16m | 16h 42m |
| Widebody jet (777, 787, A350) | 900 km/h | 14h 06m | 14h 31m |
| Private jet (Gulfstream) | 850 km/h | 14h 56m | 15h 21m |
Headwinds on an eastbound long-haul routinely add 30–60 minutes; the same route westbound can be quicker. Airlines publish schedules with padding built in.

Questions this plate answers
How long is the flight from Chicago to Dhaka?
A non-stop flight from Chicago (ORD) to Dhaka (DAC) takes about 16h 11m. The great-circle distance is 12,694 km (7,888 miles, 6,854 nautical miles), flying north on an initial bearing of 2°.
How far is Chicago from Dhaka?
12,694 kilometres in a straight line over the earth's surface — 7,888 miles or 6,854 nautical miles. Actual flown distance is usually 2–5% longer because aircraft follow airways, avoid weather and route around restricted airspace.
Is there a non-stop flight between ORD and DAC?
This page calculates the direct-line time and distance; it does not track airline schedules. At 12,694 km the route is within reach of long-range widebodies, though not every city pair is served non-stop. Check an airline or booking site for what is actually scheduled.
What should I expect on a 16h 11m flight?
Anything past six hours is a long-haul flight: expect at least one meal service, a significant time-zone shift, and enough sitting that circulation and hydration start to matter. Cabin altitude, dry air and disrupted sleep do more damage to a training routine than the flight itself.
