    In general, about 500MPH is a safe guess.

    Above 24,000 aircraft use Mach numbers (percentage of the speed of sound).

    For a CRJ (regional jet... assuming it can get to 35,000 feet that day) runs M.72-M.76.

    A B737 runs in the M.76- M.78 range. The A319/320 (another midsized aircraft like the Boeing 737) runs M.76-M.80.

    All the way up to the Corporate jets which can run anywhere from M.82 (Gulfstream 200) to M.92 (Citation X).

    I hope this helps answer your question.

    When I fly I put my phone in the window with the GPS based Speedometer app running and the most common speed I see is 560 MPH. I ve done this most commonly on a Boeing 737-800.

    Depending on the size of the jet, anywhere from 350 to 500 miles per hour.

    Airplanes fly in knots not miles per hour. 560 MPH, as the guy with the GPS app said, is 486 knots, which is about right.

    Leonard Parker and David Williams asked the same question. You should read their answers side by side.
