This thread just made me remember a question that I had about an upcoming trip. I am flying WDH-JNB-LHR-YYZ-YQT-YAG in Y - ugh!. WDH-LHR on SA, LHR-YQT on AC, and YQT-YAG on JV. The YYZ-YAG portion is on a seperate ticket. Does anybody have an idea if it will be possible to check my bags through on all 5 segments or will I have to re-check at some point.
