  • Question about Flight Numbers

    Hi, I have a small question about the flightnumbers.

    My parents flight with flight "ezy4575"
    But on flightradar24, its called "U24575 / EZY87BD".
    Can somebody explain that?

    Thanks

    You can read about callsigns and flight numbers on http://www.flightradar24.com/faq

    Generally airlines use the 2-letter IATA code as flight number, for example BA123, FR1234, SK401, LO131, LH1234, AA1234, DL301, UA500, W61501, 4U600 and so one.
    Some airports lists these flights as U2 or DS (Easyjet Switzerland) just like FR24.

    You have to ask Easyjet why they use the 3-letter ICAO code instead.

      Most every airline is using the 3-letter code for callsign/flight ID.. it's not specific to EasyJet

        I think you will find Mike is pointing out to the original poster is EZYs use of them on documents/tickets/boarding passes and information given to the public of flight numbers which do not match what is used in reality by the aircraft and in turn FR24 data.

        You can see his example uses 2 variations. Of which the 3 letter variants differ from what they tell the customer. Original Poster searched for what they are told the flight number is - "Easy 4575" - you would think, sure, so lets put 4575 after it and search FR24.. nope. Wrong - EZY4575 does not match information the aircraft sends/references or relates to the flight hes looking for - however the alternate 2 digit U24575 does. But for the alternate, all of a sudden the flight numbering is changed and added to the airline code - EZY87BD

        Whereas the others you speak of, generally do. "Delta 301" if you are told is your flight number, matches the reference with both 2 and 3 letter codes as DL301, and DAL301. Not magically changed to DAL87BD as the above example. The numbers tend to be constant. Unless you are ezyjet.

          All airlines use 3-letter code for callsigns. But this was a question about flight numbers (check topic and first post).

            It's not unusual - especially on flights wholly within europ - that there is no correspondence between the flight number and the call sign for the flight. Sometimes the easiest way to follow the flight is (on the web version of FR24.com) to setup filters on departure airport, arrival airport then have a look what is going twixt one and the other.

              Simple enough, they're not IATA members and have no interlining. So the IATA code has no relevance to them.

              However IATA allocated them U2 even though they haven't paid any subscription fees, as otherwise it was a bit embarrassing that IATA-adhering systems couldn't refer to one of the biggest airlines in Europe.

              Sometimes non-members do use their shadow-allocated IATA code where necessary, such as in HFDL, as basically they get it 'free' without being affiliated with IATA. Makes sense - saves money! Why pay $17,000 per year in membership fees when you're a stand-alone carrier?

                There is a difference between an IATA two letter and ICAO three letter airline code.
