Good news everyone. My bag(s) were found. The AC person at Winnipeg Airport had sent a message in Athens, Barcelona and Toronto and the bags were in... Barcelona.
However, they responded to AC's message twice, saying one bag was sent through Montreal and then they sent the same message that the same bag is sent through Toronto. The AC person said that probably that both bags were found and they just didn't bother typing the code for the second bag. The world tracer shows only for one bag (the one coming through Toronto. Is this accurate? I should find out today.
