I'm trying to interpret schedule data from before 1987 (see example).

Example line:

          🡓                                                                                                         🡓
20100001409B000 033504140079100000000000000000D004BOSJFK  RC0970AS     1234567  0535 BOS 0654   JFK RC 970 YQ   CVR 1           \

I'm trying to understand if this flight represents a direct flight. Specifically, my understanding is that the 9B (byte 11-12) indicates that it is a "certified direct flight". However, the 1 (byte 117) after the CVR (bytes 113-115) seems to indicate the number of stops, here more than zero. I'm trying to figure out what it means if a direct flight has stops. Some of these "certified direct flights" in my data have more than 4 stops on a short route that would not have needed a refueling stop.

Does anyone have experience in interpreting these older schedule files?

    $\begingroup$ There is a distinction between a direct flight and a non-stop flight. Is that the source of the confusion? $\endgroup$

    $\begingroup$ In short, direct flight means one flight number, nothing else. In particular, and somewhat counter-intuitively, it doesn't mean no stop or even no change of aircraft. $\endgroup$

  • $\begingroup$ @NeanDerThal, it is a set of information about scheduled flights. $\endgroup$

    $\begingroup$ From which tool/system does that come from? $\endgroup$
