I'm currently on a Rouge flight heading to YYZ. I just found a travel wallet wedged between my seat that a previous passenger left behind. It contains a US passport, boarding passes and some cash. Based on the boarding passes, it looks like they flew MCO-YYZ yesterday with the intent to continue on to HND. I'm guessing that didn't work out for them.

I have a 4 hour connection in YYZ today. What's the best way to get this back to the owner? Would AC customer service be able to assist? I am flying transborder, so bringing it to US preclearance is also possible if that's a better option.
