Questions

How long is the flight from Chicago to Prague?

A non-stop flight from Chicago (ORD) to Prague (PRG) takes about 9h 29m. The great-circle distance is 7,298 km (4,535 miles, 3,940 nautical miles), flying north-east on an initial bearing of 44°.

How far is Chicago from Prague?

7,298 kilometres in a straight line over the earth's surface — 4,535 miles or 3,940 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 PRG?

This page calculates the direct-line time and distance; it does not track airline schedules. At 7,298 km the route is comfortably within range of a non-stop service if an airline chooses to fly it. Check an airline or booking site for what is actually scheduled.

What should I expect on a 9h 29m 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.
