TLV-ATH-YUL-YYZ, A3 on first segment and AC on rest
AC BP clearly indicates ITD OSS. Baggage tag indicates through to YYZ.
Only hitch is TLV check-in agent specifically said I'd have to pick up the bag in YUL to clear customs. Am I correct this is a case of agent error (I.e., it will be checked through and I can benefit from OSS) or might the agent be right?
