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