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 | 32h 03m | 32h 28m |
| Narrowbody jet (A320, 737) | 780 km/h | 22h 36m | 23h 01m |
| Widebody jet (777, 787, A350) | 900 km/h | 19h 35m | 20h 01m |
| Private jet (Gulfstream) | 850 km/h | 20h 44m | 21h 10m |
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 Perth to Chicago?
A non-stop flight from Perth (PER) to Chicago (ORD) takes about 22h 19m. The great-circle distance is 17,630 km (10,955 miles, 9,519 nautical miles), flying north-east on an initial bearing of 55°.
How far is Perth from Chicago?
17,630 kilometres in a straight line over the earth's surface — 10,955 miles or 9,519 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 PER and ORD?
This page calculates the direct-line time and distance; it does not track airline schedules. At 17,630 km the route is at the extreme end of what any airliner can fly non-stop, so a connection is likely. Check an airline or booking site for what is actually scheduled.
What should I expect on a 22h 19m 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.
