The route
The great-circle path — the shortest line between the two airports across the curve of the earth. On a flat map it 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 | 25h 01m | 25h 27m |
| Narrowbody jet (A320, 737) | 780 km/h | 17h 39m | 18h 04m |
| Widebody jet (777, 787, A350) | 900 km/h | 15h 18m | 15h 43m |
| Private jet (Gulfstream) | 850 km/h | 16h 11m | 16h 37m |
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
How long is the flight from Bangkok to Chicago?
A non-stop flight from Bangkok (BKK) to Chicago (ORD) takes about 17h 31m. The great-circle distance is 13,763 km (8,552 miles, 7,431 nautical miles), flying north on an initial bearing of 8°.
How far is Bangkok from Chicago?
13,763 kilometres in a straight line over the earth's surface — 8,552 miles or 7,431 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 BKK and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 13,763 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 17h 31m 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.
