    only some examples in southern Europe showing routes in Germany (on RV its ok).
    Understand me right, I would like to help correcting it, not to spam. Its a nice site which should show correct data.
    Most of these routes are inserted like this in the database with the correct information, though I believe it's a bug that's displaying wrong information on the radar.
    For example you can see that http://data.flight24.com/flights/lh4138/ has an alternative callsign that is DLH62F though it matches callsign on DLH62 anyway.

    I've inserted DLH7F to the database now, though it will show the flight as DLH7 (HAM-FRA) instead of CDG-FRA untill the bug is fixed.

    You can also search on callsigns here http://data.flight24.com/ for example DLH62F and it will show up as LH4138.

    You're making a useful contribution Charky. And as you say, one for Mike, especially if another site can show the correct routes.

    I have no access to the FR24 database and don't know from where it gets its routes.

    I've just tried looking up DLH7F on 5 route websites and none has a result.

    ok, then another example: there seems to be a problem with the database at FR24 or with the callsigns.
    A lot of DLH flights showing Hamburg-Frankfurt.

    And the callsign is input by the flight crew and its not always changed or correct.

    Usually the flight number is valid for a season, summer or winter. I don't have the exact dates but it's up to the airline itself.

    In this case, correct is that LH1353 is a flight from Stuttgart (STR) to Frankfurt (FRA), but this flight has also an alternative callsign that is DLH3T.

    The DUS-PMI flight has flight number LH4406, not LH1353 and alternative callsign DLH03T.

    The problem here is most likely that the database refers to the DLH3T callsign and then it also gets flight LH1353.

    Is a flight number really unique ?

    Hi,
    example:
    FR24 LH1353 from STR to FRA wrong 24,7,2010
    flightstats LH1353 from STR to FRA wrong 17.7.2010
    correct LH1353 from DUS to PMI 24.7.2010 as DLH03T

    How often the same flight number is used for a different routing ?
    Or is a flight number only valid for one day ?
Working...
