I currently have a cash booking for a PY (low) itinerary BKK-NRT-YVR-YYZ. First segment is on ANA PY, AC PY for the rest.
I have the option of booking an award ticket in Flex PY (only 6K more than Latitude so rather have the guaranteed PY) that is instantly upgrade-able to J.
It is BKK-NRT-YYZ. (BKK-NRT in Y)
Question is: the AC portion of the itin is the same origin/destination on the same day, (however one is connecting through YVR) therefore will AC flag this as a conflict and force me to cancel one right away?
