Well, maybe this is actually only considered as two segments, I'm not sure, but anyway: The route was SGN-BKK-IST-OSL. SGN-BKK-IST is the same flight, with a technical stop in BKK, however, I had two tickets this time, one for SGN-BKK and another for BKK-IST-OSL, as I originally planed to stay overnight in Bangkok.
